What is the hot end in a 3D printer?

A hot end is the heating element in a 3D printer. It comprises several parts, including the heating element, nozzle, heat sink, and heat break.

The heating element is responsible for heating the filament to its melting point. The nozzle is a small hole through which the molten filament is extruded. And finally, the heat break limits the amount of heat that transfers to the heat sink.

These elements work together to provide an even flow of melted material and give you a smooth 3D printing experience.

What makes a good hot end?

The best 3D printer hot ends have good heat management, durability, material compatibility, and material flow rate. They minimize heat creep and maintain a stable printing temperature during extended 3D printing times. A stable hot end temperature reduces the chances of the hot end clogging up and prevents print failures.

A hot end with a high flow rate lets you print at faster print speeds and larger layer heights. This reduces print times and creates a strong 3D printed part.

Another aspect you need to consider is the material composition of the hot end. 3D printer hot ends with brass nozzles are not the best for printing with abrasive materials. Instead, you should look for hot ends with stainless steel or hard-coated nozzles. These nozzles are more wear-resistant and can handle abrasive materials better.

Similarly, if you want a hot end for 3D printing high temperature (>300°C) filaments, you are best off with a hot end with a copper-plated heater block, a high-powered heater cartridge, and a thermocouple. These hot ends can handle the higher temperatures required for printing with polycarbonate, PEEK, and other engineering-grade filaments.

Buyer’s Guide – How to Choose a 3D Printer Hot End

3D Printer Compatibility

Hot ends are not a generic component and are often designed for a specific set of 3D printers. Checking the hot end’s compatibility with your 3D printer is essential for getting the best results. It will ensure that you get the right hot end that supports your 3D printer’s hardware and electronics.

One of the things to look for is the heater cartridge voltage on the hot end. It has to match the printer’s voltage to ensure proper heating of the hot end.

You also need a mounting system for the hotend. Any additional mounting plates and hardware will translate to an increase in the cost, even though you can 3D print these yourself sometimes.

Material Compatibility

A hot end with wide material compatibility is always a good thing to have. This allows you to experiment with different materials and find the ones that work best for your needs.

The most important thing to look for is the maximum temperature that the hot end can reach. This number will give you a good idea of the range of materials that the hot end can work with.

Typical all-metal hot ends can reach up to 300 °C and can easily print most thermoplastics. This range covers PLA, ABS, PETG, Nylon, and flexible filaments like TPU and TPE.

If you need to print high-performance plastics such as PEEK, ULTEM, Polycarbonate, and PEI, you will need a hot end that has a maximum printing temperature of 500 °C.

High-performance hot ends will be more expensive than the basic ones and might not yield good results when printing at lower temperatures. If you primarily print with materials that melt below the 300 °C points, basic all-metal hot ends like the E3D V6 and the Microswiss should be enough for you.

Nozzle Compatibility

A nozzle is an important component of the hot end assembly. Nozzles are designed with their hot end’s specifications in mind. The nozzle you use defines the printing capability and material compatibility of your hot end.

A larger nozzle size will let you print fast and with large layers, while a fine nozzle is suitable for printing detailed parts. Both can be properties to look for when looking to make money with your 3D printer.

Similarly, a nozzle’s material will also affect the print quality. Nozzles made from stainless steel can handle higher temperatures and are more wear-resistant. As a result, they can last longer, but they might not be the best choice for printing with PLA.

On the other hand, brass nozzles are a good all-around choice and can be used with most materials. If you are unsure about the material of the nozzle, always check with the hot end’s manufacturer.

Due to the hot end’s design, nozzles aren’t interchangeable between 3D printer hot ends from different brands. For example, the DyzEnd nozzle is specific to the DyzEnd Pro hot end. Similarly, the E3D Supervolcano exclusively supports E3D nozzles of sizes 0.6 mm – 1.2 mm.

If you 3D print with parts of varying layer heights and with different materials, you need to ensure that you get a hot end that’s compatible with various nozzle sizes and materials.

Build Quality

A hot end is the critical component of the 3D printer and is responsible for extruding the filament smoothly. A poorly manufactured hot end will lead to many issues down the line.

Nozzle clogs, hot end jamming, filament leakage, and improper filament flow all indicate poor hot end build quality.  These issues can be frustrating and time-consuming to deal with. Checking the user reviews before you purchase the hot end will give you a better idea about its build quality.

Cheaper hot ends tend to have poor overall quality and while they might work well in the beginning, they can experience many issues after prolonged use.On the other hand, a well-manufactured hot end will have a high upfront cost and give you consistent printing performance and a high-quality experience.

Should You Buy an All-Metal Hotend or Not?

All-metal hot ends are helpful for printing materials like ABS, PETG, and Nylon. Where PTFE-lined hotends are only suitable for printing up to around 250°C, an all-metal hot end typically reaches temperatures of either 300°C or 500°C

These temperatures are more than enough for printing a wider variety of materials. The all-metal design also eliminates the need to replace the PTFE liner in the hotend over time, as the PTFE tube is no longer exposed to extreme temperatures.

However, the all-metal design can create more filament jamming issues when not configured correctly. A shorter retraction distance helps to minimize stringing and consequently prevent filament jams, however.

If you plan on printing with a lot of different materials or if you want to experiment with higher temperatures, an all-metal hot end is a good investment. Otherwise, a PTFE-lined hot end will suffice for most applications.

That said, you can’t ever go wrong with an all-metal hotend upgrade. If you simply want the best 3D printer hot end for your machine, all-metal is the way to go.

FAQ

When should I replace my 3D printer hot end?

There’s no need to replace your 3D printer hot end unless you’re looking for an upgrade to get better performance. You might have to periodically replace certain components, like the nozzle, when they wear out, however.

If you are experiencing issues with your prints, then it may be time to check your hot end for any damage or debris that may be causing problems.

Is an all-metal hot end good for PLA?

Yes. While all-metal hotends are ideal for higher-temperature filaments, they can also be used with lower-temperature filaments like PLA. Some users find that they get better results using an all-metal hotend with PLA than they do with a standard hotend with PTFE lining.

What type of hotend does the Ender 3 use?

The Ender 3 uses a PTFE-lined hot end, which allows for smoother filament flow and reduced clogging. PTFE is a low-friction material that is resistant to wear and tear, making it an ideal choice for a hot end.

If you want to upgrade your Ender 3 hot end, the Microswiss is one of the best hot ends to swap the stock one out with.

Which hot end is best?

In our opinion, the E3D V6 hotend is currently the overall best hot end on the market. It is made of high-quality materials and has a modular design that makes it easy to assemble and maintain. It also has a wide range of compatibility with different types of printers, making it a popular choice for both beginners and experienced users.

Conclusion

Choosing the right hot end for your 3D printer will extend your printing potential. The best 3D printer hot end minimizes heat creep while maintaining a stable printing temperature. However, you need to check that the hot end you select fits your 3D printing needs and is compatible with your 3D printer.

The E3D V6 hot end ranks on the top as the best 3D printer hot end. It is one of the most reliable hotends that has been well-tested over the years and is suitable with a good of materials. It has an all-metal design, broad 3D printer compatibility, and excellent build quality at a reasonable price.

Its only drawback is its limited range of printing materials. With a maximum temperature of 300°C, it won’t handle true engineering materials like PEEK.

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. nine0003

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. nine0003

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. nine0019
• 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: nine0003

• 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. nine0003

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. nine0003

Work table.

The desktop is the surface on which the filament is deposited in a predetermined form 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. nine0003

Multi-layer 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. nine0003

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. nine0019
• Third, avoid using low quality filament that may expand unevenly.
• Finally, if possible, always unload the filament when printing is complete.

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. nine0003

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 saggy. FDM printing requires a precise balance between a temperature that allows good flow and a temperature that ensures fast curing. nine0003

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 because0048 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. nine0094

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. nine0003

Higher temperatures equals more features . 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. nine0003

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)

As 3D printing research and development continues, the improved technology continues to offer even finer control over higher temperatures. These advances produce high-quality prints with difficult-to-work materials. We are excited to see what the future holds for 3D printing. Who knows what materials we will be able to print in 10 or 20 years? nine0003

Heating elements for the printer extruder (mini cartridge heating elements) and for the work table can be purchased from Heathl directly from the manufacturer. Contact us by phone or via the feedback form.

How to print flexible materials on a conventional FDM printer? Likbez from the company REK.

Along with beautiful photos and interesting videos, where someone prints high-quality models with flexible material on a regular FDM printer without any problems, there are many questions and messages on the Internet, such as “How to print with flex?”, “I generally have flex doesn’t work, what should I do?” etc. nine0003

In short, the average picture looks something like this:

It's time to end this. Likbez from the company "REK".

Foreword.

For flex printing, it is important to observe some points. Alas, not all 3D printer manufacturers create their product with the ability to print with flexible materials. But after all, you already have such a powerful tool as a 3D printer, on which you can print any desired part, so it's time to put the old joke “buy a 3D printer - print a 3D printer” into practice. The entire printer will most likely not need to be printed, but a quick and easy tuning will be needed. nine).

Hardware. extruder. The most common problem is that the extruder chews up the rod and it looks something like this (the problem area is circled):

No matter how carefully and accurately you push the flex into the extruder, after 5 seconds or after 5 minutes, it still chews up. This happens because there is a gap between the feed rollers and the entrance to the hot end or tube (bowden) channel in which the flexible rod will jam (YES, even if it is a very small gap. YES, even if there is only a couple of mm). nine0003

Familiar ABS and PLA are quite hard, they are difficult to crumple even in a centimeter gap. Flexible plastic should not be left even the slightest opportunity to go somewhere “not there”, so this gap in the extruder must be removed. For RepRap owners, this will not be difficult at all, because. they probably already have tuning experience; in free catalogs of 3D models (such as thingiverse or youmagine or myminifactory) everything has already been invented before us and there are already ready-made models of modified extruders or parts for tuning existing ones. In general, the new extruder will be different in this:

Here are some examples of tuning extruders for different printers:

Add to the list in the comments :) Hardware #2. Hot end. (Let's give this thing a normal Russian name). Not all “hot ends” (hot ends) are equally useful and this needs to be corrected. nine0003

This moment, by the way, concerns not only flexible rods, but also often causes difficulties when printing PLA.

The essence of the problem lies in the fact that the bar, getting into the hot end, begins to melt even before it reaches the nozzle, and a so-called “plug” from the material melt appears, which is not easy to push through. If a rigid PLA rod can still push through the melt due to the power of the extruder, then such a trick will not work with a flexible material - it will wrinkle, bend and curl even in those places where it seemed impossible. Very often, owners of 3D printers in frustration call such a situation “nozzle clogged”, although this is not entirely true. nine0003

The picture below shows a schematic of a hot end. Where the color indicates the normal state of the bar during the printing process. (blue indicates where the rod is still hard, red indicates where it begins to melt)

In this state, the plastic will exit the nozzle quite calmly without any difficulty, but if the heat goes higher, the rod will begin to melt earlier (in the cold zone) and will create additional resistance for the extruder. Solution: cool the top of the hot end by any means. Put the fan on the hot end, smear the heatsink (if any) with thermal paste at the junction with the hot parts, make the air flow directed (to the hot end), etc.
