Welcome back to the world of 3D printing! Have you ever wondered why, in 2022, most 3D printers don’t come equipped with heated chambers? Well, it’s a common question, and today, we’re here to shed light on this topic. You might be surprised to learn that heated chambers play a crucial role in achieving high-quality 3D prints, especially when working with high-temperature thermoplastics. So, why are heated chambers so important, and how do they impact your printing experience? Let’s delve into the details.
The Chamber Conundrum
You might have noticed that many 3D printers lack heated chambers. In fact, some printers have no chamber at all. The natural question that arises is, “Why are heated chambers often absent, and is there any point to having them?” To address these questions, let’s begin by understanding the role of heated chambers in 3D printing.
When Heated Chambers Matter
For certain 3D printing materials like PLA, having a heated chamber might not be essential. PLA and PETG are among the few materials that can be successfully 3D printed without the need for a heated chamber. However, the story changes when you venture into the realm of high-temperature thermoplastics.
High-temperature thermoplastics include materials like ABS, Nylon, Polycarbonate, and exotic options like PEEK and PSU. These materials are notorious for their propensity to warp as they cool down. Even if you’ve managed to lay down those first layers at temperatures as high as 250 degrees Celsius, the problem arises when you’re printing taller parts. As you move upward from the heated bed, the layers you’ve already printed remain hot, and the rest of the part cools down to ambient room temperature. This temperature gradient creates a phenomenon called the coefficient of thermal expansion, which can lead to stress and warping in your printed parts. Warping, in a nutshell, is a 3D printer’s worst nightmare.
The Role of Heated Chambers
Now, this is where the heated chamber comes to the rescue. The principle behind a heated chamber is simple but effective. By maintaining a consistent and elevated temperature within the chamber, you minimize the temperature differential between the printed part and the ambient environment. This, in turn, reduces the internal stresses and prevents warping.
Consider, for instance, the example of printing ABS. ABS prints its first layers at a scorching 250 degrees Celsius. With an actively heated chamber, the entire part, from bottom to top, remains at a relatively stable and high temperature. By ensuring uniform temperatures during the entire printing process, a heated chamber helps to minimize structural strain and improve the part’s overall quality.
Materials that Demand Heated Chambers
When working with high-temperature thermoplastics like PEEK, Ultem™, PSU, ABS, Nylon, and Polycarbonate, having a heated chamber becomes almost imperative. While it’s possible to print these materials without a chamber in certain scenarios, the results can be far from satisfactory. The absence of a heated chamber can lead to structural issues, warping, and poor dimensional accuracy. In other words, you won’t get the performance you expect from these high-temperature materials.
Choosing the Right 3D Printer
As you explore the 3D printer market, you’ll find a wide range of options, from affordable models to high-end machines. So, which one should you choose? The answer largely depends on your specific needs. If you’re printing aerospace-grade parts or materials that require extremely high chamber temperatures, invest in a 3D printer with the highest chamber temperature capabilities available.
However, if your goal is to create strong and functional parts or achieve chemical resistance, you can explore various 3D printers with lower chamber temperatures. The key is to match your printer to the type of parts you intend to create and the materials you plan to use.

The Learning Curve
If you’re new to 3D printing, be prepared for a learning curve. 3D printing isn’t a one-button microwave-like process; it’s more akin to mastering a CNC machine. To become proficient, you’ll need to understand your printer’s settings and how they interact with your chosen materials. Part of the learning process is observing how your material behaves with different geometries, part sizes, and the transfer of heat throughout the print.
And that’s where the true value of 3D printing lies—being able to explore uncharted territory, discover unique challenges, and find innovative solutions. While it may not always be easy, the journey is immensely rewarding. With the right mindset and a willingness to learn, you can overcome challenges, achieve precision, and create incredible parts. The return on investment for 3D printing is astounding, and the possibilities are limitless.
