3D printing is still a bit of a wild frontier in technology, but the category has matured to the point that it’s now affordable—and even kid-friendly. Essentially, 3D printers connect to your computer and let you create just about anything you can imagine that will fit inside the printer. There’s also a vast repository of fun stuff to try out over at Thingiverse, a sort of Google for 3D-printable objects.

So let your kids design, print and enjoy stuff they make. And if adults want to get in on the fun, there are options on this list for everyone in the family. Before you shop, it’s a good idea to get familiar with the basic terms used to describe 3D-printing technologies. Keep in mind you’ll also need to buy filament for your printer, which is like buying ink for your printer.

Here are the best 3D printers for kids:

FlashForge Finder

The FlashForge Finder 3D Printer - The Best 3D Printers For Kids

The FlashForge Finder is a real-deal 3D printer that both kids and adults can use with confidence. FLASHFORGE

I like the FlashForge Finder 3D Printer because it’s packed with all the features I like in regular 3D printers, but it’s been resized and rethought for younger users. It uses a cold printing deck so burns aren’t really an issue, and the big touch panel makes operation a snap. You can print from Wi-Fi, the cloud or a thumb drive. Best of all, the prints look great. Plus, it’s quiet, a big bonus since you might want to let the printer work away on a big project overnight. For $299, this is a solid choice for kids, teens and adults interested in doing some 3D printing.

For the last five years we've invested in the 3D printing world, using as many printers as we can to see what is good and what is bad. We all know that printing can be expensive — there are machines out there that start at $3,000 and go up from there — so we want you to have some idea of what you can get for cheaper. When it comes to value and quality you can't beat the Prusa i3 MK3. While it isn't the cheapest of the machines on this list, it is easily the best quality in terms of build and print.

Best Overall: Prusa i3 Mk3

In the world of hobbyist 3D printing, there are few names as well known as Josef Prusa. His work in open source 3D printing has revolutionized what can be done at home and on a budget for those who want to create amazing prints. The Prusa i3 MK3 is the latest machine based on his open source design and is easily the most advanced printer in this list.

The Prusa has automatic bed leveling, making each print start the best it can, but it also corrects the print on-the-fly if anything happens to shift the bed. With a sensor in the extruder, the Prusa can tell when you run out of filament, pause the print, and alert you to add more, saving countless mistakes in the process. From the removable bed to easily being able to remove prints without breaking them to the excellent save function, which stops your prints being lost in a power cut, the Prusa goes out of its way to make every print work.

The listing is for the kit version of the i3 mk3 so you will be required to build it yourself. Prusa does supply a fully made one but it's $200 more when you add in the extra shipping. Which one you buy will depend on your preference, but we recommend getting the kit. Plus, it's actually a lot of fun learning to build one from scratch.

Pros:

Auto bed leveling

Excellent print quality

Open source

Active community

Save functionality

Cons:

Cheaper to buy the kit

Best Value: Creality Ender 3

The Creality Ender 3 is a shining example of how a community can get together, take something cheap and flawed, and turn it into something special. The Ender 3 is not a printer for someone who wants quality prints straight of the box — you have to earn them. Sure, it's easy to get set up and it doesn't take much other to put together — just a few screws —but to get a print that you can be proud of takes effort.

The Ender 3, while being cheap, it is not configured well by Creality. The extruder setup is poor, as are a lot of the acceleration settings and because of that, it can take endless fine-tuning. Don't be dismayed though, there are people out there who are willing to help put you on track.

I never would have gotten the Ender 3 to the point of usability without the help of the Facebook and Twitter 3D printing communities, and I strongly urge you to look into those places if you intend to buy an Ender 3. Especially check out Filament Frenzy on Twitter. He can make the Ender 3 sing and dance like magic.

Of course, if you have the time to spend on it, $220 for a full-size printer that can make some fantastic prints is a bargain. If you have time to love it, it can be a great investment.

Pros:

Extremely cheap

Simple setup

Can create amazing prints

Cons:

Can take a lot of work to get right

Best For Your Desk: Monoprice Maker Mini Pro

If you are completely new to 3D printing and want something simple, reliable, and cheap, you can't do much better than Maker Mini Pro by Monoprice. The printer itself is small enough and quiet enough to sit on the desk in your office and allow you to make small, fun little projects fairly quickly. The Mini has several high-end features like Wi-Fi connectivity, along with the SD Card and direct PC connection that you normally get with larger printers.

It even comes with auto bed-leveling, which can be picky but is a great addition. There's also a heated bed for printing with multiple types of filament, something you'd expect on a more expensive printer, all wrapped in a sturdy metal body that reduces the "noise" often associated with cheaper printers. With a 4.75-inch print bed, the Mini is the smallest of the printers on this list, but if you are just starting out in 3D printing and only want to experiment, the small bed is more than enough.

With the Bowden extruder setup already a part of the Mini the results of printing are significantly better than I ever thought a $200 printer would produce. I helped my local youth room purchase three of these so the young people there can learn how to design and print in 3D and so far the only issue I have had is a blocked nozzle and an uneven print bed, both of which are the basic foibles of 3D printing and easily fixed by anybody.

Pros:

Auto bed leveling

Fits on your desk

Wi-Fi printing

Heated bed

Cons:

The print bed is really small

Best Value Delta: Monoprice Mini Delta

When I first used the Mini Delta I was ready to write it off from the start — $160 for a delta printer? It was obviously going to suck. Turns out, I was wrong. I like the Delta for a lot of reasons including its portability, it's build quality, as well as its great print quality. None of those things are as awesome as the price though. For just $160 you can have a 3D printer of your own that works as soon as you turn it on.

The interface on the Mini Delta is incredibly simple, making it perfect for youngsters and first-timers who aren't interested in taking things apart to make them work. The printer has three buttons and each one is self-explanatory, helping you get printing straight away. The nature of delta printers — delta printers use three constantly moving servo arms instead of rods and screws — means this mini model is dependable, even when being jostled. A delta, once dialed in, will give you great prints even under the worst of circumstances.

I was blown away by the print quality of this little machine and, even though it can only make really small models, it remains one of my favorites to have close by for small, quick jobs. The only issue I sometimes have is the auto-leveling is sometimes a little off and you will need to manually adjust or use a product like Magigoo to help keep it all stuck down.

Pros:

Solid as a rock

Great print quality

Simple interface

Portable

Cons:

Small

Bed leveling is janky

Best Value Resin: AnyCubic Photon

Resin printing can be expensive. The machines themselves are normally high-priced and the resins can be even pricier. Resin printing differs from the other printers on this list because it uses a liquid plastic that is cured over a UV light or shot with a laser. It can be messy, difficult, and a little dangerous so it's best to know what you want before you buy.

Somehow Anycubic made an affordable resin printer that produces some of the best quality prints I've seen from a printer under $2,000. The prints from a resin printer are gorgeous and are often impossible to tell that they are 3D printed. They often look like injected molded models.

Using Chitubox — a slicer now used by a large number of 3D printer manufacturers — to slice the models is simple and effective and makes the entire process of printing models on the Photon a breeze. One word of warning though: make sure your supports are thick in Chitubox since they can be a little wimpy if you aren't careful.

Of all the resin printers that I have owned and used the Photon is the one I recommend to friends, and therefore to you, dear readers. It's dependable and accurate every time.

Pros:

Entry level price

Almost invisible layer lines

Simple to use

Excellent slicing

Cons:

Small build plate

Chitubox can be tricky

How much does a 3D printer cost?・Cults

How much does a 3D printer cost? This question is asked by many beginners, hobbyists and enthusiasts. While the answer may be a little complicated, our goal is to simplify the process and help you choose the right printer for your skill level. There are many different 3D printers on the market. Some are small, cheap, and designed for do-it-yourselfers, others are full of features and cost much more.

However, this does not mean that you have to spend a fortune to get a good printer. The cost of 3D printers has come down a lot over the years and you can now find good 3D printers for under $300. While they may not have some of the features found on a $20,000 printer, you can still use them to create interesting projects. Many of these cheap printers are for beginners, hobbyists, or those who want to learn how to 3D print.

So how much does a 3D printer cost? Basically, you can find starter models for $200. Mid-range consumer models start at around $700, while commercial or high-end consumer models will set you back thousands of dollars. In this article, we will answer some questions about 3D printers and provide you with an informative guide to choosing the best printer for your skill level.

If you're an engineer, artist, inventor, hobbyist, or just a tinkerer, a 3D printer is definitely worth it. 3D printers are very useful for creating models of machines, parts, fixtures, gears, and other complex shapes. This technology is used in many areas, including aerospace, medicine, all kinds of mechanical engineering, etc.

If you love building, fixing and fiddling with things, a 3D printer can be a great addition to your equipment. However, if you're not into any of the above areas or hobbies, getting a 3D printer might not be worth it. In addition, before purchasing a printer, you need to make sure that you are technically literate enough to operate it. This is because such printers require regular updates/upgrades and the learning curve can be quite steep.

You will need to regularly buy filaments, learn how to design in 3D CAD or use other modeling software. Also, you may have to fiddle with your machine settings before you find the right fit. If you are completely new, using a 3D printer will take you a lot of time and you may end up spending a lot of money on filaments and other materials. However, once you get the hang of it, 3D printing can quickly turn into one of the most enjoyable activities or hobbies one can indulge in.

In addition to the initial purchase cost, the cost of using a 3D printer can quickly increase depending on the model you purchase. For the cheapest models, you will have to constantly buy printer upgrades. Therefore, it is recommended to purchase a high-quality printer with better specifications so that you do not have to upgrade from time to time.

Another item that can increase the cost of a 3D printer is filaments. They usually sell for around $25 per kilo, so beginners are advised to buy them in small quantities. This is because you will need multiple colors to create models, and buying a kilo of each can quickly add up to hundreds of dollars. Another thing you will waste is time. If you're just getting started, you'll have to take the time to learn about your printer, how to make great 3D prints, the right software and updates, color combinations, material composition, and many other important factors.

Definitely yes. In fact, there are many different ways to make money with 3D printers. Below are the top four ways to make money with these printers:

  • Prototyping and Selling : You can make money by offering to prototype for local engineering firms. Since 3D printing involves learning how to create 3D designs, you can sell your designs or create designs for engineering firms.
  • Sell your prints : You can sell your printed objects online. Create a website or social media campaign and sell your designs. You can also create custom prints for your clients; they will provide you with the design and you will print it for them.
  • Sell your designs : You don't have to print to make money. You can just sell your 3D designs and skip the whole printing process.
  • Teach others : Many people are interested in the knowledge you have about printing. Engineers, students, DIYers and hobbyists will be happy to learn from you. You can simply charge them and teach them how to use and set up their own printers, what materials to use, how to print, and so on.

As we noted above, the cost of 3D printers has dropped significantly because there are now models that have few features but are cheaper. Basically, there are five different types of 3D printers based on price. These are entry-level printers for hobbyists, enthusiasts, professional and industrial printers. The price of machines in each category depends on the functions, size and capabilities of the machine. Let's take a closer look at each of these categories:

Entry level 3D printers

Entry-level 3D printers designed for beginners. They are mainly used to climb the learning curve. You can buy these to learn how to 3D print before moving on to higher models. While you won't be able to create complex prints, you will be able to understand how a 3D printer works.

This type of printer has its limitations. First, you won't be able to print more than 3-4 inches in any dimension, be it height, width, or length. Also, many of these printers do not allow you to use more than one media at a time. In addition, they are slow and noisy, and the quality of their products is not as beautiful as that of expensive models. Also, the highest resolution that most entry-level printers offer is 100 microns.
In addition, entry-level printers are not very durable. However, they are a great learning tool and can serve as a good stepping stone to dive deeper into the world of 3D printers. Now to answer the question, how much does a 3D printer cost? A typical entry-level printer will cost between $200 and $400.

3D printers for hobbyists

Hobbyists are those who have plunged into the world of 3D printing a little, fell in love with it and were carried away by it. They just want to improve their 3D printing skills by making models just for fun. Although 3D printers in this category are slightly better than entry-level models, they still cannot offer a result that goes beyond fun creativity. Their build volume is larger and you will be able to make more models with these printers. 3D printers for hobbyists allow you to create designs as small as 5-6 inches. Prints are thinner than entry-level printers and usually have better software.

They are faster than entry-level models and allow more flexibility in material selection. This means that with machines in this category you can be even more creative. However, it is important to note that while they may be better than entry-level models, they are not very durable and their performance is not reliable. This means that they may not be able to withstand too much load, and you will not be able to use them for a long time. So how much does a 3D printer cost? They usually cost between $300 and $1500. There are many different products on the market in this price range and choosing the right one can be a daunting task. We recommend taking a look at this guide to 3D printers under $500 from HotRate.

3D Printers for Enthusiasts

Becoming a 3D printing enthusiast means you've decided to level up and now consider it more than just a hobby. This is a big leap that requires better and more powerful hardware than those in the hobbyist category. Printers in this category are known for their reliability and high build volume. They are quieter and slightly faster than hobbyist machines. In addition, they can print up to 12 inches in any dimension and allow for a wider choice of materials.

However, they also have their downsides. Some of them only work with branded media, which means you can't just buy any type of media and run it into the printer. Also, while their prints and output are usually better than hobbyist printers, they cannot be used for production. This is because they are not professional machines and cannot be used for a long time.
You will need regular maintenance and repairs. Enthusiast 3D printers are ideal for regular use, but can break down with constant use. How much does a 3D printer in this category cost, you ask? Be prepared to spend $1500 to $3500.

Do you consider yourself experienced enough and would like to monetize your 3D printing skills? Or maybe you just want to take your hobby to the next level by creating professional models? Be that as it may, a professional 3D printer is one that is capable of working for you. The print quality on them is first class and they are capable of printing up to 12 inches in any dimension. In addition, they are flexible regarding materials. You can use a variety of media in the machine without worrying about color or texture. They can also print faster than the categories we talked about earlier without sacrificing quality.

The price of a printer for a professional printing press is quite high. Therefore, to ensure that you are purchasing the best 3D printing machine, be sure to read real user reviews. Consider the pros and cons of the machine you want to purchase. Read up on how to maintain it, what materials to use, how best to set it up, etc. Make a list of important factors and go through them one by one.
The price of a printer for machines in this category is expensive, so checking all the right boxes before making a purchase decision is very important. So back to our original question, how much does a 3D printer cost in this category? A typical professional 3D printer costs between $3,500 and $6,000. They are commonly used by robotics clubs, schools, and businesses large and small.

Industrial 3D printers designed for serious print businesses. They are simply the best and fastest cars in all categories. Their characteristics are at the highest level, they are very durable, as they are made of metal. In addition, their interfaces are user-friendly and they are very efficient. Industrial 3D printers are large and can accommodate many different types of custom prints. They also come with a hefty price tag, but that's to be expected given the fact that they're made for businesses and their construction is top-notch.

Industrial 3D printers are large and heavy, which can be a problem if you don't have enough space. In addition, the cost of 3D printing with these machines can run into the thousands of dollars over time. Obviously, these machines consume more electricity, materials and require a high level of maintenance than printers in other categories. That is why they are recommended only for enterprises and manufacturers. So how much does a 3D printer in this category cost? The price of a printer for industrial 3D machines ranges from $20,000 to $100,000.

How to build a home 3D printer: recommendations from personal experience

3D printing and assembly of 3D printers is my hobby and passion. Here I will not share detailed diagrams and drawings, there are more than enough of them on specialized resources. The main goal of this material is to tell you where to start, where to dig and how to avoid mistakes in the process of assembling a home 3D printer. Perhaps one of the readers will be inspired by applied engineering achievements.

Why do you need a 3D printer? Use cases for

I first came across the idea of ​​3D printing back in the 90s when I was watching the Star Trek series. I remember how impressed I was by the moment when the heroes of the cult series printed the things they needed during their journey right on board their starship. They printed anything: from shoes to tools. I thought it would be great someday to have such a thing too. Then it all seemed something incredible. Outside the window are the gloomy 90s, and the Nokia with a monochrome screen was the pinnacle of progress, accessible only to a select few.

Years passed, everything changed. Around 2010, the first working models of 3D printers began to appear on sale. Yesterday's fantasy has become a reality. However, the cost of such solutions, to put it mildly, discouraged. But the IT industry would not be itself without an inquisitive community, where there is an active exchange of knowledge and experience and who just let them dig into the brains and giblets of new hardware and software. So, drawings and diagrams of printers began to surface more and more often on the Web. Today, the most informative and voluminous resource on the topic of assembling 3D printers is RepRap - this is a huge knowledge base that contains detailed guides for creating a wide variety of models of these machines.

I assembled the first printer about five years ago. My personal motivation to build my own device is quite prosaic and based on several factors. Firstly, there was an opportunity to try to realize the old dream of having your own device, inspired by a fantasy series. The second factor is that sometimes it was necessary to repair some household items (for example, a baby stroller, car elements, household appliances and other small things), but the necessary parts could not be found. Well, the third aspect of the application is "near-working". On the printer, I make cases for various IoT devices that I assemble at home.

Agree, it is better to place your device based on Raspberry Pi or Arduino in an aesthetically pleasing "body", which is not a shame to put in an apartment or take to the office, than to organize components, for example, in a plastic bowl for food. And yes, you can print parts to build other printers :)

There are a lot of scenarios for using 3D printers. I think everyone can find something of their own.

A complex part in terms of drawing that I printed on my printer. Yes, it's just a figurine, but it has many small elements

Ready solution vs custom assembly

When a technology has been tested, its value in the market decreases markedly. The same thing happened in the world of 3D printers. If earlier a ready-made solution cost simply sky-high money, then today acquiring such a machine is more humane for the wallet, but nevertheless not the most affordable for an enthusiast. There are a number of solutions already assembled and ready for home use on the market, their price range ranges from $500-700 (not the best options) to infinity (adequate solutions start from a price tag of about $1000). Yes, there are options for $150, but we, for understandable, I hope, reasons, will not dwell on them.

In short, there are three cases to consider a finished assembly:

  • when you plan to print not much and rarely;
  • when print accuracy is critical;
  • you need to print molds for mass production of parts.

There are several obvious advantages to self-assembly. The first and most important is cost. Buying all the necessary components will cost you a maximum of a couple of hundred dollars. In return, you will receive a complete 3D printing solution with the quality of manufactured products acceptable for domestic needs. The second advantage is that by assembling the printer yourself, you will understand the principles of its design and operation. Believe me, this knowledge will be useful to you during the operation of even an expensive ready-made solution - any 3D printer needs to be serviced regularly, and it can be difficult to do this without understanding the basics.

The main disadvantage of assembly is the need for a large amount of time. I spent about 150 hours on my first build.

What you need to assemble the printer yourself

The most important thing here is the presence of desire. As for any special skills, then, by and large, in order to assemble your first printer, the ability to solder or write code is not critical. Of course, understanding the basics of radio electronics and basic skills in the field of mechanics (that is, "straight hands") will greatly simplify the task and reduce the amount of time that needs to be spent on assembly.

Also, to start we need a mandatory set of parts:

  • Extruder is the element that is directly responsible for printing, the print head. There are many options on the market, but for a budget build, I recommend the MK8. Of the minuses: it will not be possible to print with plastics that require high temperatures, there is noticeable overheating during intensive work, which can damage the element. If the budget allows, then you can look at MK10 - all the minuses are taken into account there.
  • Processor board. The familiar Arduino Mega is well suited. I didn't notice any downsides to this solution, but you can spend a couple of dollars more and get something more powerful, with a reserve for the future.
  • Control board. I'm using RAMPS 1.4 which works great with the Arduino Mega. A more expensive but more reliable board is Shield, which already combines a processor board and a control board. In modern realities, I recommend paying attention to it. In addition to it, you need to purchase at least 5 microstep stepper motor controllers, for example - A4988. And it's better to have a couple of these in stock for replacement.
  • Heated table. This is the part where the printed element will be located. Heating is necessary due to the fact that most plastics will not adhere to a cold surface. For example, for printing with PLA plastic, the required table surface temperature is 60-80°C, for ABS - 110-130°C, and for polycarbonate it will be even higher
    There are also two options for choosing a table - cheaper and more expensive. Cheaper options are essentially printed circuit boards with preheated wiring. To operate on this type of table, you will need to put borosilicate glass, which will scratch and crack during operation. Therefore, the best solution is an aluminum table.
  • Stepper motors. Most models, including the i2 and i3, use NEMA 17 size motors, two for the Z axis and one each for the X and Y axes. Finished extruders usually come with their own stepper motor. It is better to take powerful motors with a current in the motor winding of 1A or more, so that there is enough power to lift the extruder and print without skipping steps at high speed.
  • Basic set of plastic fasteners.
  • Belt and gears to drive it.

This is a list of items to be purchased. Hardcore users can assemble some of them themselves, but for beginners, I strongly recommend purchasing ready-made solutions.

Yes, you will also need various small things (studs, bearings, nuts, bolts, washers ...) to assemble the case. In practice, it turned out that using a standard m8 stud leads to low printing accuracy on the Z axis. I would recommend immediately replacing it with a trapezoid of the same size.

M8 trapezoid stud for the Z axis, the use of which will save you a lot of time and nerves. Available for order on all major online platforms

You also need to purchase customized plastic parts for the X axis, such as these from the MendelMax retrofit kit.

Most parts available at your local hardware store. On RepRap you can find a complete list of necessary little things with all sizes and patterns. The kit you need will depend on the choice of platform (we'll talk about platforms later).

What's the price

Before delving into some aspects of the assembly, let's figure out how much such entertainment will cost for your wallet. Below is a list of parts required for purchase with an average price.

Platform selection

The community has already developed a number of different platforms for assembling printers - the most optimal case designs and the location of the main elements, so you do not have to reinvent the wheel.

i2 and i3 are key platforms for self-assembly printer enclosures. There are also many modifications of them with various improvements, but for beginners, these two classic platforms should be considered, since they do not require special skills and fine-tuning.

Actually, illustration of platforms: 1) i2 platform; 2) i3 platform

On the plus side of i2: it has a more reliable and stable design, although it is a little more difficult to assemble; more opportunities for further customization.

The i3 variant requires more special plastic parts to be purchased separately and has a slow print speed. However, it is easier to assemble and maintain, and has a more aesthetically pleasing appearance. You will have to pay for simplicity with the quality of printed parts - the body has less stability than i2, which can affect print accuracy.

Personally, I started my experiments in assembling printers from the i2 platform. She will be discussed further.

Assembly steps, challenges and improvements

In this block, I will only touch on the key assembly steps using the i2 platform as an example. Full step by step instructions can be found here.

The general scheme of all the main components looks something like this. There is nothing particularly complicated here:

I also recommend adding a display to your design. Yes, you can easily do without this element when performing operations on a PC, but it will be much more convenient to work with the printer this way.

Understanding how all components will be connected, let's move on to the mechanical part, where we have two main elements - a frame and a coordinate machine.

Assembling the frame

Detailed frame assembly instructions are available on RepRap. Of the important nuances - you will need a set of plastic parts (I already talked about this above, but I'd better repeat it), which you can either purchase separately or ask your comrades who already have a 3D printer to print.




The frame of the i2 is quite stable thanks to its trapezoid shape.

This is how the frame looks like with parts already partially installed. For greater rigidity, I reinforced the structure with plywood sheets

Coordinate machine

An extruder is attached to this part. The stepper motors shown in the diagram above are responsible for its movement. After installation, calibration is required along all major axes.

Important - you will need to purchase (or make your own) a carriage for moving the extruder and a mount for the drive belt. Drive belt I recommend GT2.

Calibration and adjustment

So, we completed the assembly process (as I said, it took me 150 hours) - the frame was assembled, the machine was installed. Now another important step is the calibration of this very machine and extruder. Here, too, there are small subtleties.

Setting up the machine

I recommend calibrating the machine with an electronic caliper. Do not be stingy with its purchase - you will save a lot of time and nerves in the process.

The screenshot below shows the correct constants for the Marlin firmware, which must be selected in order to set the correct number of steps per unit of measure. We calculate the coefficient, multiply it, substitute it into the firmware, and then upload it to the board.

Marlin 9 firmware constants0093

For high-quality calibration, I recommend relying on larger numbers in measurements - take not 1-1. 5 cm, but about 10. So the error will be more noticeable, and it will become easier to correct it.

Calibrating the extruder

When the frame is assembled, the machine is calibrated, we start setting up the extruder. Here, too, everything is not so simple. The main task of this operation is to correctly adjust the supply of plastic.

If underfeeding, the printed test item will have noticeable gaps, like test die 1. Conversely, the result will look bloated if plastic is overfed (dice 2)

Getting Started Printing

It remains for us to run some CAD or download ready-made .stl, which describe the structure of the printed material. Next, this structure needs to be converted into a set of commands understandable to our printer. For this I use the Slicer program. It also needs to be set up correctly - specify the temperature, the size of the extruder nozzle. After that, the data can be sent to the printer.

Slicer interface

As a raw material for printing, I recommend starting with regular ABS plastic - it is quite strong, products made from it are durable, and it does not require high temperatures to work with. For comfortable printing with ABS plastic, the table must be heated to a temperature of 110-130 ° C, and the extruder nozzle - within 230-260 ° C.

Some important details. Before printing, calibrate the machine along the Z axis. The extruder nozzle should be approximately half a millimeter from the table and ride along it without distortion. For this calibration, a regular sheet of A4 paper inserted between the nozzle and the surface of the heated table is best suited. If the sheet can be moved with little effort, the calibration is correct.

Another thing to keep in mind is the surface treatment of the heated table. Usually, before printing, the surface of the table is covered with something that hot plastic sticks to well. For ABS plastic, this can be, for example, Kapton tape. The disadvantage of adhesive tape is the need to re-glue it after several printing cycles. In addition, you will have to literally tear off the adhering part from it. All this, believe me, takes a lot of time. Therefore, if it is possible to avoid this fuss, it is better to avoid it.

An alternative option that I use instead of scotch tape is to apply several layers of ordinary light beer, followed by heating the table to 80-100 ° C until the surface is completely dry and re-applying 7-12 layers. It is necessary to apply the liquid with a cloth moistened with a drink. Among the advantages of this solution: ABS plastic separates from the table on its own when it cools down to about 50 ° C and is removed without effort, the table does not have to be peeled off, and one bottle of beer will last you for several months (if you use the drink only for technical purposes :)).

After we have collected and configured everything, we can start printing. If you have an LCD screen, then the file can be transferred for printing using a regular SD card.

The first results may have bumps and other artifacts - do not worry, this is a normal process of "grinding" the printer elements, which will end after a few print cycles.

Tips to make life easier (and sometimes save money)

In addition to the small recommendations given in the text above, in this section I will also give a short list of tips that will greatly simplify the operation of a 3D printer and the life of its owner.

  • Do not experiment with nozzles. If you plan to immediately print from materials that require high temperatures, then it is better to immediately take the MK10 extruder. On MK8, you can "hang" special nozzles that support high-temperature conditions. But such modifications often cause difficulties and require special experience. It is better to avoid this fuss on the shore by simply installing the right extruder for you.
  • Add starter relay for heated table. Improving the power supply system of this important part for printing with a starter relay will help solve the known problem of RAMP 1.4 - overheating of the transistors that control the power of the table, which can lead to failure of the board. I made this upgrade after having to throw away a few RAMPS 1.4s.
  • Select the correct filament diameter for printing. Recommend 1.75mm plastic for MK8 and MK10. If we take plastic, for example, 3 mm, then the extruder simply does not have enough strength to push it at an acceptable speed - everything will be printed much longer, and the quality will drop. ABS plastic is ideal for MK8, MK10 will be able to produce products from polycarbonate.
  • Use only new and precise X and Y guides. Print quality will be affected. It is difficult to count on good quality with bent or deformed guides along the axes.
  • Take care of cooling. In the course of my experiments with various extruders, the MK10 showed the best results - it prints quite accurately and quickly. The MK10 can also print plastics that require a higher print temperature than ABS, such as polycarbonate. Although it is not as prone to overheating as its younger brother MK8, I still recommend taking care of its cooling by adding a cooler to your design. It must be permanently enabled, this option can be configured in Slicer. You can also add coolers to keep the stepper motors at an acceptable temperature, however, make sure that their air flows do not fall on the printed part, as this can lead to its deformation due to too rapid cooling.
  • Consider heat retention. Yes, on the one hand, we are struggling with overheating of the elements. On the other hand, a uniform temperature around the printer will contribute to high-quality printing (the plastic will be more pliable). To achieve a uniform temperature, you can put our printer, for example, in a cardboard box. The main thing is to connect and configure the coolers before that, as described above.
  • Consider insulating your desk. Heated table heats up to high temperatures. And if part of this heat leaves properly, heating the printed part, then the second part (from below) just goes down. To concentrate the heat from the table onto the part, you can perform an operation to insulate it. To do this, I simply attach a cork mouse pad to its bottom using stationery clips.

Pins

I am sure that during the assembly process you will encounter a number of difficulties specific to your project. Neither this text nor even the most detailed guides will insure against this.

As I wrote in the introductory part, the above does not claim the status of a detailed assembly manual. It is almost impossible to describe all the stages and their subtleties within the framework of one such text. First of all, this is an overview material that will help you prepare for the assembly process (both mentally and financially), understand whether you personally need to bother with self-assembly - or give up on everything and buy a ready-made solution.

For me, assembling printers has become an exciting hobby that helps me solve some issues in home and work affairs, take my mind off programming and do something interesting with my own hands. For my children - entertainment and the opportunity to get unusual and unique toys.
