HeyGears UltraCraft GreenPrint Air Purifier
VOC control for resin 3D printing workspaces.
GreenPrint uses photocatalysis and a second degradation reaction to break down volatile organic compounds (VOCs). Designed for printing areas in dental practices and laboratories, it supports ongoing air purification during resin printing.

Key benefits
- Direct VOC breakdown with dual degradation technology.
- 92% TVOC reduction in 25 minutes in a 10 m² room in HeyGears laboratory testing.*
- Three fan speeds, Sleep mode, a timer and a colour-coded TVOC display.
- Long-term photocatalytic purification without routine replacement of conventional VOC adsorption filters. Dust filter strips still require maintenance.

How GreenPrint works
The purification system decomposes VOCs rather than relying only on storing them in an adsorption filter. Performance depends on the chemical compounds present and operating conditions; the published test results do not establish equal removal of every chemical odour.



Performance and test conditions
Room test: HeyGears reports a 92% decrease in total volatile organic compounds (TVOC) within 25 minutes in a 10 m² room.

Continuous-emission test: With continuous VOC injection equivalent to emissions from more than three 3D printers, HeyGears reports reducing and maintaining TVOC around 0.3 mg/m³ within two hours.
*Manufacturer laboratory results, not a guarantee for every workspace. Actual performance varies with VOC composition, emission rate, room conditions and use. The reported 0.3 mg/m³ is a test result, not a universal safety threshold for individual chemicals. Use alongside suitable ventilation.

Maintenance and service life
The photocatalytic system is designed for long-term use. The separate dust filter strips may need replacement every 3–6 months, depending on dust loading, according to the HeyGears Quick Start guide. Keep the air inlet and outlet unobstructed.
Service life and purification performance depend on operating conditions and maintenance.

Setup and care
Use the supplied adapter with a nearby 100–240 V outlet. The Quick Start guide specifies a level floor, protection from direct sunlight, 18–25°C and humidity below 50% RH. Allow the 180-second start-up preheat. Do not clean the unit with alcohol or organic solvents.
