Researchers at Western College have launched SpecOptiBlend, an open-source software program bundle that permits the creation of custom-colored supplies from recycled plastic waste. Revealed in Superior Manufacturing, the brand new software permits customers to match particular coloration necessities when changing waste plastic into 3D printing filament. The software program makes use of spectral reflectance knowledge and coloration mixing strategies to rework recycled supplies into exact coloration formulations.
The event addresses a earlier limitation in distributed recycling and additive manufacturing (DRAM), the place customers have been restricted to authentic waste plastic colours or primary combined shades. Based on Professor Joshua Pearce, Thompson Chair in Innovation at Western College, the crew efficiently matched particular colours like “Western’s regal purple” and the pink petals from a LEGO wildflower set. The software program employs numerous optimization strategies to attain correct coloration matching.
“Now we have pushed plastic recycling to the following degree, as a result of now you will get {custom} colours in your 3D prints that aren’t even accessible in the marketplace,” explains Pearce. “Prior to now you both needed to be proud of the colours your waste plastic got here in or combine them collectively and get boring gray.”
The analysis crew examined three optimization strategies, with the Nelder-Mead strategy offering the most effective steadiness between coloration accuracy and root imply sq. measurements. Their paper, “Creating {custom} 3D printing materials colours utilizing optical modeling of waste plastic,” is now revealed in Superior Manufacturing and the software program is freely accessible for public use.
