3D printing system maker Onulis has launched an industry-first machine capable of turning expired UV resin into a solid, safe disposable plastic.
Built around Onulis’ patented Axial Waste Resin Printing (WRAP) technology, the W7500 enables users to recycle used or expired UV raw materials into materials that do not require specialized end-of-life disposal. According to its creators, the fully automatic machine’s ability to reuse resin allows it to “operate at virtually zero cost” while producing plastics with potential product prototyping applications.
Decryption of “WRAP” technology
Founded with the stated goal of developing products that help solve the biggest problems in 3D printing, the new launch of Onulis targets one of the most problematic problems in resin printing: waste disposal. Right now, the company claims that disposing of used or expired UV resin forces manufacturers to adopt either “messy DIY methods” or expensive services, which are forced “to simply bury sealed drums. of hazardous materials in landfills “to solve the problem. problem.
If manufacturers choose to go it alone, the long chore of resin removal is to first manually expose thin layers of the used material to the sun, before stirring the partially cured polymers to continually reveal uncured undercoats. . This painstaking process must then be repeated until the material is fully cured, in a workflow that may involve exposure to caustic materials.
Additionally, if a hazardous waste management company is hired, the manufacturer will first be required to register with the Environmental Protection Agency as a producer of this waste. In such cases, users are then required to store large drums of waste on site until sufficient quantities are collected for pickup.
The W7500 alleviates these issues, while allowing for faster, safer, and more conscientious recycling, and the plastic generated by the printer is effectively zero-cost inventory, which is ideal for use in CNC machining or manufacturing. product design.
Onulis W7500 Resin Recycler
Now available to manufacturers, the first machine powered by Onulis’ WRAP technology, the W7500, features a space-saving form factor, allowing it to be compact while retaining a 7.5 liter capacity, and wide compatibility. means it is capable of handling waste and expired resins from SLA, DLP, PolyJet and MultiJet 3D printers as well.
With its auto-sync functionality and axial printing architecture, the W7500 can run unattended and it also has built-in carbon filtration. As a result, the system works to prevent users from being exposed to toxic gases often created during the manual curing of UV resins. The unit also offers impressive efficiency, allowing users to process thirty days of resin waste in just six hours.
Industry tested innovation
Early adopters of the W7500 include users from several different industries, ranging from academia to medical device manufacturers and 3D printing service providers, with early customers keen to demonstrate its material efficiency benefits.
“Our new W7500 has saved us huge amounts of time and money,” says Matthew DeGroat, service desk manager at California parts supplier and adopter of Onulis Purple Porcupine. “We are pleasantly surprised that beyond simply saving money, we have been able to minimize our team’s contact with hazardous waste and refocus our work on tasks with higher added value. ”
