Magnetic heatbed 3d printer

With the development of 3D printing, a lot of new research and experiments have appeared. Many of them are aimed at finding the best way to increase the adhesion of the first layer.

And we all know why this is so important. A standard heated 3D printer table will do the job. Although there are other alternatives when working with the first layer, nothing compares to this one.

Most importantly, 3D printer tables are a very important part of the overall design. In fact, without a table, you will not be able to create physical embodiments of your 3D models. Therefore, understanding how you can make the best use of the table should be your top priority for quality 3D printing. Understanding and navigating the different types of heated tables and their features will definitely help you choose the right 3D printer and implement your own ideas.

But before we get into all the 3D printer heated tables, let's understand what 3D printing is. Most of us are already aware of this, but a brief overview will ensure that we are on the same wavelength in the context of the current article.

What is 3D printing?

We have been hearing about additive manufacturing or 3D printing for a long time. And the lucky ones who had a chance to work with this technology at least once are becoming more and more every day.

3D printing has become one of the most revolutionary technologies and is spreading very quickly, influencing the entire ecosystem of production, industry and hobby.

3D printing is a process in which 3D printers create layers one on top of the other to create a finished product of the desired shape and dimensions.

3D printing may differ in the principle of creating 3D models. For example, there are FDM, SLS, SLA and many others. They differ in the way the layers are created and connected. However, the fundamentals remain the same. Layers are stacked on top of each other to build the entire 3D model.

3D printing has made it possible to create extremely detailed models and designs in a short amount of time and in many cases cheaper than classic manufacturing processes. But when using a 3D printer, certain precautions must be taken to ensure that the finished product exactly matches the desired characteristics.

However, 3D printing has its own problems. And the biggest of them is too fast heating and cooling of the layers of the 3D model. One of the major problems that arise from improper heating/cooling is shrinkage. It changes the shape of the 3D model and deforms it. Therefore, in this case, we get low-quality products.

To solve this problem, heated tables for 3D printers have appeared. These tables, among other things, are designed to maintain the required temperature of the first layers of the model and the entire model as a whole. They help control the temperature during the entire 3D printing process. Therefore, this additionally results in proper adhesion of the first layer throughout the entire 3D print time of your model.

What is a heated 3D printer bed?

Returning to the main topic of the article, we must answer the question: what is a heated table for a 3D printer? Although we have already briefly discussed the usefulness of heated tables, let's learn more about them.

Heated tables using printed circuit boards as a heating element

Heated tables for 3D printer designs may vary. Among the most common types of heated tables, mounting or printed circuit boards are used as heating elements. They usually come with budget 3D printers. However, this solution is not very suitable if your 3D printing projects are complex and require frequent work with a 3D printer. In short, they are designed for small projects that do not take much time to complete.

The reason why they are not suitable for complex 3D printing is that PCBs are made of copper and aluminum plates, and they are prone to deformation when heated for a long time. Over time, heated plates will no longer perform the task for which they were originally designed.

There is another problem that may arise. They take longer to heat up. You can get rid of this problem, but for this you will need to replace the power supply with a more powerful one.

Heated tables using AC silicone sealant for heating element

The second type of heated 3D printer table is one that uses silicone to seal the heated elements. To create a structure, a heated element is inserted between pieces of glass and a heat insulator.

This is to minimize excess heat leakage and to deliver maximum heat to the table surface. In addition, electricity consumption also becomes smaller. And they can work longer without causing any problems to users.

This version of the heated table design is much more reliable and can last you much longer. In addition, the bill for the consumed electricity will also be reduced due to the minimization of losses for heating the table.

3D printer process with heated table

The 3D printer works by extruding a plastic filament onto the table. Immediately after exiting the extruder, the material begins to cool. As we all know, shrinkage goes hand in hand with the cooling process. The problem arises when the layer is not cooled uniformly at all points. This leads to uneven shrinkage and, ultimately, to deformation of the entire 3D model.

To avoid cooling the plastic at different rates at different points, heated tables have been developed. The job of a heated 3D printer bed is to ensure that the parts do not cool completely until the 3D print is complete. This allows for a more uniform shrinkage process.

In short, heated tables basically take care of two things. First of all, by increasing the surface energy of the printing table, the heated layer enhances the adhesion of the first layer. Secondly, a sufficiently high temperature of the lower layer is ensured, which avoids the problem of deformation at any stage of the 3D printing process. Therefore, the heated bed maximizes efficiency and avoids excessive cooling of the layers.

When material hits the 3D printer bed through the extruder, it carries a certain amount of heat with it. For best results, the temperature of the heated bed should be below the glass transition point. This should turn the liquid thread into a solid form. The temperature sensor is responsible for maintaining the required temperature of the table.

You may need to experiment to find the optimum table temperature, as the melting point of different materials and manufacturers is different.

Several DIY Heated Table Designs for 3D Printer

We have already discussed the basics above, now let's look at some interesting DIY solutions.

In addition to the PCB and the sealed AC heating element, there are other DIY designs to replace your table with a heated table.

Polyamide film heater

Polyamide, which we also call Kapton, offers a huge advantage when used as a tape for printable surfaces. They are best suited for use with PLA plastic. Providing effective heat resistance and high adhesion for PLA printing, this film is very popular. The use of this film helps to improve the surface quality of 3D models.

However, you may not know that in combination with a heating element sandwiched between two polyamide films, you can get a polyamide film heater. In addition, they are easy to install by adding glue to the back. They heat up very quickly. In addition, they can be of different shapes and sizes. So this is a great option to upgrade your 3D printer table.

Aluminum Coated 3D Printer Heater

If you are looking for an efficient and cost effective solution, this is the one for you. However, keep in mind that installing these heaters on your 3D printer may require some work.

After installing the heaters, it is necessary to close the electrical circuit using a thermistor and an insulator. Last but not least, the thermal paste must remain between the lined heater and the build surface.

Do you need a heated table for your 3D printer?

Since many 3D printers do not have a heated bed, the question is, do you need a heated bed?

You may have heard that working with PLA plastic does not require a heated table. Or perhaps you've only heard of ABS printing on a heated table. But what is the truth?

When 3D printing with ABS you will need a heated table. Why is that? ABS tends to compress more than other materials. Therefore, the likelihood of deformation increases when 3D printed using ABS. With the table heating turned on, the material will better set on the first layer, minimizing potential deformations at the edges of the 3D model.

What about PLA? Do we need a heated table or not? In the case of PLA, heating is not always needed. However, if you want to print large models, it is better to use a heated bed to eliminate the possibility of possible problems.

As mentioned above, you also need to know the optimum temperature for your material. Otherwise, there will be no point. For example, when working with ABS, it is recommended to heat the table to 110 ° C. On the other hand, when using PLA, it is worth stopping at 60 ° C. By the way, the temperature of the 3D printer table is set at the stage of processing the model in the 3D slicer.

3D Printer Heated Table Precautions

Heated tables maintain very high temperatures, so you should take the necessary precautions.

Heated tables can leave scars for life if they come into contact with the skin.
