ColdMetalFusion

引入金属3 d打印ql系列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.
