Comparison between the properties of polyamide 12 and glass bead filled polyamide 12 using the multi jet fusion printing process [PDF]

Additive Manufacturing, 2020
Abstract This study investigates the material and mechanical properties of both polyamide 12 (PA12) and reinforced glass bead PA12 composites, fabricated using a production scale additive manufacturing (AM) process. The printing studies were carried out using the production scale, Multi Jet Fusion powder bed fusion process.

Performance Comparison of Surface Sensitizers for Diode Laser Powder Bed Fusion of Polyamide 12

Advanced Engineering Materials, EarlyView.
Laser‐generated nanoparticles transform standard PA12 powders into high‐performance, dye‐free feedstocks for diode laser 3D printing. Despite identical absorbance at 808 nm, CuS, LaB6, and CB coatings reveal striking differences in fusion and strength—unlocking new design space for recyclable, industrial‐grade polymers.

Polyamide 12/E-glass Fabric Composite Production with Dip-coating

MATEC Web of Conferences, 2018
In this study PA12 was reinforced with E-glass woven fabric by dip-coating. PA12 powder and ethanol suspensions were prepared with ratios at 30, 40 and 50% of powder to obtain different fibre contents. Coated fabrics were laid-up and kept in oven at 60°C
