Metal filament

Metal filament

This category of metal filament for debinding/sintering is very specific and does not correspond to your usual search for metal-look filaments typically used in 3D printing. Here, you will use your 3D printer to create in two steps a 100% metal part with metal properties rather than plastic.

The technique used here involves a plastic matrix densely loaded with metal powder. The filament form is necessary for handling this powder via our 3D printer, and the use of a plastic binder is required.

Printing green metal parts

Printing with your printer using these metal-filled filaments will give you what is called a green part. This part has no mechanical, thermal, or chemical properties and should not be used as-is. This printing step allows you to create the metal and plastic-loaded part that will need debinding to be functional.

Debinding process

This first step lets you use a composite metal filament to produce your 3D model in a traditional way. The second step is what gives this filament its full value. Through one or more chemical-thermal post-processing steps, the binder is removed, leaving only the metal. At high temperatures and under pressure, the metal will fuse, sintering and solidifying into your final part now that the plastic is gone.

To summarize, these metal-based filaments are used as follows:

1. 3D printing
2. Debinding / Sintering

These two steps cannot be completed in-house, as the processing phase requires a specific type of furnace. Our manufacturers offer services to carry out these complex post-processing steps for you.

Print metal parts using your desktop 3D printer

You can print these filaments on any FDM 3D printer capable of reaching the required extrusion and bed temperatures. We recommend using an enclosure or filtered cover and avoiding major temperature fluctuations. Additionally, we offer a special adhesive for use with metal filaments.

Important point: the filament density on the spool is very high, so a 2 or 3 kg spool can fit on a typical 750g reel. Don't be surprised if 750g spools are not offered, as they would contain too little filament length.

Why choose debindable/sinterable metal filament?

Quite simply, to produce metal parts with your plastic FDM 3D printer. This innovative two-step process will revolutionize metal additive manufacturing by making it accessible to everyone—without needing to invest in advanced post-processing equipment or powder technologies. For metal part production, think 3D printing too.
