When it comes to 3D printing metal, there are people who may choose to use a laser cutter instead. The reason is that 3D printed projects using metal can be costly and time-consuming. However, the two are quite different. 3D printing is an additive process, while laser cutting is a subtractive process. Depending on your needs, those that are looking to create multiple pieces at a quicker pace may choose the laser cutter as it can conveniently cut multiple materials and larger size.

With digital trends of raw and rustic design, you might be considering 3D printing cool things at home with metal. However, printing metal is extremely costly due to its process and the machinery required. If you’re looking for cool things to 3D print at home with a metal-looking finish, we recommend using materials on the market that can create metal-like 3D printed objects instead. These materials give the illusion that your 3D printed pencil holder or camera mount is made out of metal but without the actual cost.

Thanks to 3D printing, it has also made highly-customizable prosthesis possible. One of the coolest things about 3D printed prosthesis is that they can create custom fits for the patient and also a much lower cost. Instead of creating static designs that are “one size fits all”, 3D print gives companies the opportunity to create products that are affordable and personalized. What would have cost lots of money to create is now more accessible thanks to 3D printed prostheses.

Beyond science, 3D printed homes and shelters have also become one of the cool things to 3D print across the world. To address the housing issue around the world, companies have been using this technology to print emergency shelters and 3D printed homes. With this technology, companies and cities can build a community in a much shorter amount of time and for a cost cheaper than traditional home building methods. Each home inside the community can then be purchased at a more affordable cost.

If you love architecture and buildings, companies have created kits that allow people to replicate architectural structures and other cool things with a 3D pen. For boardgame lovers, you 3D print your own figurines by drawing it with your 3D pen. You can also turn your favorite cartoon show characters or movie heroes into 3D. While a 3D pen allows you to draw 2D things to 3D, their limitation tends to be the size of the project you can make. If you’re looking to 3D print a life-size chair, it may be easier to use a printer because 3D pens may not be able to create something as durable.

3D Printing: All about Heatle

The heating of plastic filaments in specialized printers equipped with heated extruders and print beds creates the basis for the formation of products from molten filaments, also known as 3D printing.

Currently, 3D printers are being used to create tools, camera equipment, medical models, phones and tech accessories, home decor items, toys, and fashion, just to name a few. The applications for 3D printing are almost limitless.

Since 2009, when the main patent for portable 3D printers expired, 3D printing has grown into an industry of its own. As a result, 3D printers are one of the defining products of our time.

3D printers are now being used to create just about anything you can imagine - tools, camera equipment, medical models, phone and personal technology accessories, home decor, toys, and fashion, just to name a few. Its applications are almost endless. Theoretically, any solid object can be made with 3D printing. Although some limitations in technology prevent printing in certain sizes and materials, research and development is rapidly expanding the possibilities.

The most popular type of 3D printing is Fused Deposition Modeling (FDM). Modeling the product on the printer is done by melting and extruding a spool of plastic filament through the nozzle as it moves up, down and across the specified XYZ coordinates.

Creating a product using the FDM process looks something like this:

3D model created using software.
The model is exported as a stereolithography file (. stl format) and then imported into the slicing software.
The file is split into product layers and specific tool paths are generated.
The design is sent to the printer.

Within minutes - or possibly hours or days, depending on the size and complexity of the part - the part is made by additive manufacturing.

3D printing heater

3D objects are made by melting, molding and cooling plastic.

Several key components create and manage heat in an FDM printer:

Extruder.
Work table.
Multi-layer cooling fan.

A closer look at each of them will explain how they affect the print result.

Extruder.

The extruder is where most of the printer technology resides. It consists of a cold end that pulls the filament through the system and a hot end that melts the filament as it is extruded.

Inside the hot end of the extruder is a heating block. As a rule, this is an aluminum element with a hole for a cartridge heating element. The heating element melts the filament as it passes through the heat pipe and reaches the nozzle.

The extruder also has a fan heatsink. This cooling element helps prevent heat from entering parts of the extruder that need to be kept at cooler temperatures.

Another element of the extruder worth mentioning is the thermistor or thermocouple. This temperature sensor detects and helps regulate the temperature of the hot end.

Work table.

The desktop is the surface on which the filament is deposited in a given shape during the printing process. Most PCBs are heated to prevent the plastic from cooling too quickly and deforming the product. Printtables typically maintain temperatures somewhere between 50 and 100°C. Specific temperature requirements depend on what type of plastic is being used.

Some printers do not have heated stages. These machines are limited in the materials they can print with. Also, materials may not adhere to these layers and melted parts are more likely to pop out of the middle of the print.

Multilayer cooling fan.

The cover fan cools the plastic after exiting the nozzle. This element helps the created product to keep its shape when printed.

Heat control: solving heating problems

Since 3D printing is so dependent on heating temperature, any temperature issues can easily disrupt the entire process. Common problems encountered in 3D printing include

Thermal creep
Deformation and bending.
Melted or deformed articles.
Cracks on the sides of the taller item.
Slope or bend at the bottom (elephant foot).
Blurry or undefined first layer.

Manufacturers can face such problems due to non-ideal temperatures.

As 3D printing research and development continues, advanced technology offers even more precise control over higher temperatures, producing high-quality printed products from difficult-to-work materials.

Thermal creep

Heat creep occurs when heat is distributed unevenly through the hot end of the extruder. This happens when the filament cools as it is extruded and heat travels up the thermal barrier tube. This will cause the filament to heat up and swell too early and stick to the walls of the thermal barrier tube. Heat creep can cause clogs that stop printing, and such clogs are difficult to remove.

As a result, thermal barrier tubes are often designed to prevent thermal creep. The teeth or filaments in the pipe help prevent heat from entering places where it is not needed. In addition, there are several preventive measures that can be taken to prevent a negative effect.

First, ceramic insulation tape must be added around the heater block.
Second, when the printer is not printing, do not leave it hot.
Third, avoid using low quality filament that may expand unevenly.
Finally, if possible, always unload the filament when you finish printing.

Deformation and bending.

Product distortion occurs when the plastic is cooled too quickly after extrusion. Because the plastic shrinks slightly when cooled, rapid cooling can cause the plastic to bend as it solidifies.

Warping can be prevented by keeping the plastic just below its melting point on the print bed. If warping occurs, the temperature of the print engine may need to be increased.

Melted or deformed seal.

Excessive heat is to blame when printed pieces look droopy. FDM printing requires a precise balance between a temperature that allows good flow and a temperature that ensures fast curing.

To fix melted prints, adjust the temperature settings . First, make sure the temperature is within the appropriate parameters for the material. Then try decreasing the nozzle temperature by 5°C at a time.

Cracks on sides of higher prints.

Sometimes when the higher pieces are 3D printed, cracks can appear between some of the higher layers. This is because these layers too far away from the heat of the printed layer . After extrusion, the filament cools too quickly and is not as tacky as it should be. This results in small spaces or cracks between the layers.

To prevent the filament from cooling too quickly, try to increase the temperature of the extruder by about 10°C.

Slope or bend at the base.

Bending or warping near the base of printed objects occurs when the weight of the model presses on the lower layers before they cool down properly.

This deformation of the lower layers is eliminated by faster cooling. This can be achieved by lowering the platen temperature by 5°C at a time until the desired results are achieved.

Blurry and undefined first layer.

Sometimes the first layer can be blurry. When this happens, the corners feel vague and the filaments look messy. This usually happens because0066 The print bed is too hot and this causes the plastic to lose its shape.

The solution to this problem is probably pretty obvious. It may be necessary for to reduce the temperature of the platen by 5°C at a time until the desired results are achieved.

The threads come in a variety of colors and textures and offer effects ranging from glow in the dark to the look and smell of wood.

Material temperature limits

There are several filament options for . The threads come in a variety of colors, textures and offer effects ranging from glow in the dark to the look and smell of wood. An important part of mastering the use of these different materials is understanding the specific temperature requirements for each material. Failure to comply with these parameters may result in any of the temperature related problems mentioned.

Higher temperatures equals more capability . When 3D printers can maintain higher temperatures during production, more filament options become available. However, working at higher temperatures requires special technology in a 3D printer.

For example, it is not uncommon for extruder hot ends to be made up of both metal and polyetheretherketone (PEEK) or polytetrafluoroethylene (PTFE). While PEEK and PTFE provide excellent insulation, they limit the hot end temperature to no more than 240°C. However, when all-metal hot ends are used, temperatures can be effectively maintained above 300°C. This opens the door to the use of a range of different materials.

New developments in FDM technology are paving the way for even higher temperatures during 3D printing. Last year, a 3D printer manufacturer introduced a line of high-temperature printer components that allow the hot ends of an extruder to reach temperatures in excess of 400°C. Printtables on the same devices can reach temperatures in excess of 200°C.

Ideal temperatures for various materials:

Polylactic acid (PLA)

Acrylonitrile butadiene styrene (ABS)

Polyamide (nylon)

Polyethylene terephthalate (PET / PETG / PETT)

Acrylonitrile styrene acrylate (ASA)

Polypropylene (pp)

Thermoplastic elastomer (TPE)

Thermoplastic polyurethane (TPU)

Wooden Threads

Polycarbonate

Polyvinyl alcohol (PVA)

As 3D printing research and development continues, the improved technology continues to offer even finer control over higher temperatures.
