The choice of materials expands in 3D printing


Materials for 3D printing are becoming increasingly high- performance, and often more environmentally benign than earlier options. By Simon Robinson


The range of choices facing today’s 3D printing company is wider than ever and materials manufac- turers have listened to the demands of users and the downstream markets. For example, Arkema has partnered with Authentic Material to offer what it claims are “innovative and more sustainable materials for luxury goods markets and beyond”. The companies said they are working together to harness Arkema’s position in the design, manufacture and recycling of advanced bio-circular material and the propri- etary expertise of Authentic Material in leather recycling.

Qilin products. These can be 3D printed but can also be processed by traditional extrusion or moulding processes, said the French company. Qilin products for luxury goods, fashion, sports equipment, consumer electronics and automotive interior components were launched in 2024. Initially the products are using bio-based PA 11


Rilsan grades derived from castor oil. David DuPont, Vice President of Specialty Polyamides at Arkema, add that “We are working on 100% recycled polyamide 11 as part of our Virtucycle in-house recycling system.” Noémie Dumesnil, Chief Operations Officer at Authentic Material, said her company had decided to meet customers’ demand for “high performance in terms of luxurious feel and long-term durability.
