When it comes to 3D printing, the innovative production capabilities open up a new world of possibilities for creators and makers, but some precautions should be followed to ensure 3D printing workspaces are as safe as they can be. Be it resin or Filament (FDM) 3D Printing, there are volatile organic compounds (VOCs) which may be emitted during the 3D printing process, causing uncomfortable odors and can be unhealthy with prolonged exposure. Due to this, having good ventilation in a 3D printing area and the use of air purification are always recommended. To tackle this directly, HeyGears has recently announced its GreenPrint Purification Unit as a new option specifically for resin 3D printing users.
What are the things that need to be considered when choosing the right form of air purification for your 3D printing workspace? Let’s take a look at the features and capabilities that may help you choose the best VOC air purifier type for your 3D printing setup. This guide will take you through some of the information you need to know about why a purification unit is strongly recommended, and also some of the different types available.

Why Should You Consider a Dedicated VOC Air Purifier for 3D Printing?
If exposure is not adequately managed with good ventilation or air purification, the VOCs given out by 3D printing may prove harmful to your respiratory system or hurt your health. VOCs are emitted during FDM extrusion or resin printing and are popular types of 3D printing materials. These substances often smell bad and are uncomfortable for some users. To avoid adverse impact on health, the exposure should be managed through good ventilation and ideally purification.
A specific VOC air purifier targeting 3D printing VOCs offers a direct way to tackle these issues. As opposed to the common-use purifiers, it is designed to focus on the VOC pollutants from the 3D printing process.
Why Traditional Air Purifiers Aren’t Enough
Standard air purifiers are normally focused on limiting dust, pollen, and other common indoor air particles and annoyances. They may trap the particles and air pollutants in HEPA and carbon filters, but do not destroy them. When using these filters in 3D printing workspaces, they can get saturated rather fast. Even worse, VOCs may not be removed from the air when the adsorption capacity of the filter gets oversaturated, and, in some cases, captured VOCs could also be re-released into the environment.
Simply put, these were not specifically designed to deal with 3D printing workspace environments. Instead, you will need to replace filters regularly - paying more in the long term, and run the risk of exposure to VOCs that were not properly captured by the filter.
What are the Advantages of VOC Air Purifiers Designed for 3D Printing?
First of all, a dedicated 3D printing VOC purifier such as the HeyGears GreenPrint, degrades polluting VOCs via photocatalysis and other methods instead of retaining them - breaking down the VOC emissions of resin printers into H₂O and CO₂.
A VOC-removing air purifier like this is constructed to meet the consistent use requirements of 3D printing, with no filter replacement required, and provides an effective breakdown of VOC emissions. In short, it provides enhanced protection from VOCs by directly breaking them down in 3D printing workspaces.

Key Features to Consider When Choosing the Best 3D Printing VOC Air Purifier for Your Setup
When you go out to buy the best VOC air purifier for 3D printing, these are the key features you should consider:
VOC Elimination: Are you looking to do more than just filter out VOCs? Then consider purifiers that utilize direct VOC degradation methods.
Filterless Operation: Want to avoid frequent filter replacements? Then consider units that can purify without costly consumables.
Continuous Purification: Look for a purifier suitable to run for long periods to meet the requirements of longer 3D printing runs and night printing jobs.
Noise Levels: Try to get units that are not too loud, and offer whisper-quiet modes as needed, particularly for small workshops or at-home studios.
Purification Efficiency: Look for details on purification efficiency changes over time, along with relevant data on TVOC reduction.
Size & Portability: The unit should fit into your workspace without compromising on power.
Get to Know the HeyGears GreenPrint VOC Air Purifier
What might be best for a resin 3D printing setup? Among the newest of such devices in 2025 is HeyGears’ UltraCraft GreenPrint Purification Unit, specifically designed to tackle VOCs in resin 3D printing workspaces. In comparison, unlike conventional air purifiers, the unit does not use traditional filter replacements. Rather, it consists of two deep-degradation technologies that employ photocatalysis and degradation reactions to neutralize VOCs, breaking them down into H₂O and CO₂.

Reasons why this may be a great choice for your 3D printing workshop and workspace:
No filters, it just works: GreenPrint is designed to operate with a stable efficiency over time without the need for filter replacements..
High Efficiency: HeyGears lab tests indicate that the concentration of TVOCs can be reduced by 92% within 25 minutes in a room with an area of 10 m².
Stable long-term performance: Even with continuous output of VOCs from multiple 3D printers, like resin 3D printers, it keeps the TVOC levels within safe limits.
Quiet Operation: It runs between 47 to 60 dB(A), it’s perfect for studios or shared spaces.
Compact and Powerful: Measuring 270x270x520 mm and designed to operate well in rooms around 30 m², it offers the appropriate size vs capability ratio.
It is not just the technology, but the level of performance and VOC breakdown capabilities that GreenPrint provides in actual 3D printing conditions, which makes the difference. Whether you are running a single SLA/mSLA/DLP 3D printer or multiple printers together, GreenPrint tackles VOCs to provide safer and more comfortable 3D printing workspaces and workshops.

Conclusion
3D printing is, without a doubt, one of the most thrilling innovations defining contemporary creativity, productivity and manufacturing, yet with innovations comes responsibility. Your printer, slicer, and filament or resins are not the only things to consider in your setup: a safe 3D printing environment is also an essential factor. Finding the best VOC air purifier for your 3D printing setup is an important step to creating a safer and healthier 3D printing experience. In the year 2025, the HeyGears GreenPrint VOC air purifier is leading the pack in providing a convenient, non-filter-based, and highly effective solution for breaking down VOCs and keeping resin 3D printing workspaces safe and productive.
