3D printer hardens waste resin for safe disposal

The W7500 3D printer solidifies UV waste resin that can be discarded or repurposed, says the manufacturer, Onulis. Current ways to dispose of waste resin include messy do-it-yourself methods or contracting a costly removal service.

Leveraging the company’s WRAP (Waste Resin Axial Printing) technology, the W7500 automatically converts used or expired UV waste resin into solid plastic stock, reportedly as safe for disposal as standard household waste. The printer separates waste into droplets for thorough curing via a patent-pending drip system. There are no pumps, valves, or hoses, which are susceptible to clogs. Integrated safety features allow unattended operation. Stock can be disposed of or used as low-cost media for prototype machining or to produce colorful objects.

The printer has a vat capacity of 7.5 l, processes resin at 1 l/hr., measures 26.5 (wide) by 16.5 (deep) by 28.7 (high) in., and weighs 60 lbs.
