Two new low-gloss additive masterbatches for PLA and PETG FDM (fused deposition modeling) 3D printed systems are newly being offered by . Insight LAA112 Low Gloss PLA and Insight TCA112 Low Gloss PETG masterbatches have been shown to reduce gloss and improve the aesthetic profiles of 3D printed objects with minimal to no impact on mechanical properties. (Image: Cat depicted on the right incorporates the low-gloss masterbatch.)

Explains director of operations A.J. Pasquale, “Conventional 3D printed parts with high-gloss accentuate layer-lines and other defects suggesting lack of durability, or prototype and single-use only applications.” Typical use level is 10% to 30%. “Additive manufacturing is now used for producing finished goods rather than prototypes for injection molds. So we facilitate that trend by producing masterbatches that make end-products more aesthetically acceptable to the customer.” With FDM filament being used as the final article and 3D printing now a manufacturing technique, Dr. Pasquale said the resulting piece must be aesthetically 100% good, not 90%.Moreover, FDM and other techniques are accepted now for low volume manufacturing. The 3D-printed part, therefore, must present a high-quality appearance that earns customer acceptance.

While the current low gloss masterbatches are designed specifically for FDM, Insight Polymers can develop materials for SLS (selective laser sintering) and BAAM (Big Area Additive Manufacturing), according to customer interest.
