Metal FFF

Material Ease of Use
High

As easy as to change material as an FFF printer, no PPE required for the printer and minimum PPE for the Wash/Sinter

Facility Requirements Moderate

The Metal 3D Printer has no special requirements, the Wash and Sinter require extraction

Metal fused filament fabrication (FFF) is the most accessible, easy to use, and affordable type of metal additive manufacturing technology in a three step process. Metal FFF uses bound metal powder and sintering – a high energy process that turns the 3D printed parts into a fully solid metal.

Step 1 PRINT: metal powder is printed one layer at a time. Parts get scaled up to compensate for shrinkage during sintering. Step 2 WASH: after printing a part you have what is called a green part. Green parts are placed into the wash station which uses a debinding fluid to dissolve the plastic material around the metal powder.

Step 3 SINTER: after your parts have been washed they are known as brown parts. Brown parts are placed in a furnace where they are heated to burn away remaining binder material and solidify metal powder.

FAQ’S

Commonly asked questions about Metal FFF additive manufacturing

Yes it can be, certainly for low volume production. What sets metal 3D printing apart is that it has a consistent cost per part which is not dependent on print volume. The process is pretty much automated so there is no big reduction in labour if you print 100 parts or 1, the cost is in the consumables.
Typically conventional metal fabrication is subtractive i.e. starting with a block of metal and removing material to create a final part; taking time and wasting metal. Certain complex geometries are impossible to produce via subtractive manufacturing methods eg. parts with complex curves or cavities

There are 4 things you can do for the best possible printing results

  • Identify the critical dimensions
  • Maximise contact with the print bed
  • Reduce supports
  • Think about batch processing

Get in touch with us at Additive-X for a helpful Design Guide for Metal 3D printing which explains what you should do and why

Well, thicker parts take longer to wash, so you can try increasing surface area and hollowing out large volumes to cut the wash time down
