The CoLiDo AMSS Metal 3D printer is an affordable metal additive manufacturing system for professionals. CoLiDo, a brand that usually manufactures desktop 3D printers, is based in China with headquarters in the US and the UK.

This affordable metal 3D printer targets small businesses and start-ups. Indeed, according to CoLiDo, the AMSS is 20% less expensive than other major metal 3D printing systems.

AMSS metal 3D printing technology

CoLiDo’s proprietary AMSS 3D printing technology is somewhat similar to FDM/FFF (Fused Filament Fabrication). AMSS stands for Additive Manufacturing Selective Sintering.

Extrusion

To 3D print metal objects, the AMSS Metal 3D Printer uses specific metal filament that contains a binding agent. The maximum build size, at this stage, is 200 x 200 x 300 mm.

De-binding

Then, when the actual 3D printing is complete, the object must go through a high-temperature de-binding process to remove the binder material.

Sintering

After that, the object goes through another high-temperature process: sintering. This makes the object more compact, as the missing binder leaves small spaces after de-binding. The maximum build size therefore shrinks to 170 x 170 x 225 mm.

Post-processing

Finally, to make metal 3D printed objects smoother, users can choose to post-process them. This step is optional, but for end-use parts it may be useful as the objects have a rather rough surface.

AMSS Metal 3D Printer main features

• Constant temperature: this 3D printer maintains a specific temperature inside its build chamber.
• Nozzle cleaning system: for smooth metal filament extrusion.
• Filament sensor: the AMSS will stop 3D printing if it detects a break in filament or if it runs out.
• Power resume: in case of a power failure, the 3D printer is able to continue where it last left off.
