Introducing Metal 3D Printing for QLS Series SLS Printers
ColdMetalFusion is now available for all QLS series SLS printers. This innovative metal 3D printing process combines high-throughput laser sintering with established powder metallurgy processes to deliver metal components with exceptional performance, repeatability and precision.
Scalable, Economical, and Support-Free Metal 3D Printing
ColdMetalFusion with QLS enables cost-effective serial production of up to 100,000 parts per year. With this process, you can:
Print freely, uninhibited by the constraints of traditional manufacturing or the limitations of direct metal laser melting processes
Rely on uniform processing that takes the guesswork out of secondary binding processes.
Eliminate time-consuming and costly post processing like support removal, heat treatment, and stress relief
Reduce waste and material costs with reusable feedstock and without unnecessary support structures
How Metal 3D Printing with ColdMetalFusion Works
ColdMetalFusion (CMF) is a proven process that’s very similar to metal injection molding but with the added design freedom and fast production typically associated with 3D printing. Utilizing patented metal powder feedstock from Headmade® Materials, this unique feedstock has a thin polymer coating over each metal particle used to bond particles together during the sintering process. Each particle is sintered at a low temperature in Nexa3D’s fast-cycle QLS printers, and once printed, parts go through a validated debinding and sintering process to burnout and remove the polymer, resulting in fully-metal components.
