Bluesint PA12

Bluesint PA 12 recycling

Bluesint PA 12 is a more sustainable rapid prototyping alternative to the PA 12 SLS material. Previously, prototyping with traditional laser sintering meant that about 70% of the unsintered powder became waste. But with Bluesint PA 12, we can use that unsintered powder to build brand-new parts. The result is a printed part with mechanical properties similar to traditional PA 12 but printed with 100% re-used powder, reducing carbon footprint by about 30%.

How Does Laser Sintering Work?

Laser Sintering is a laser-based technology that uses solid powder materials, typically plastics. A computer-controlled laser beam selectively binds together particles in the powder bed, by raising the powder temperature above the glass transition point after which adjacent particles flow together. As the powder is self-supporting, no support structures are necessary.
