Hi,

I work as a continuous improvement engineer and I've been discussing getting a 3D Printer for our shop here. Main applications would be:

  • Prototyping tools, jigs, parts, etc
  • Small custom parts for use on equipment

The main thing I'm struggling with is there's so much technology and brands now! I decided to reach out for more insight. The main requirements are essentially:

  • Food safe plastic OR Metal Detectable plastic (plastic with metal impregnated)

I would appreciate any help or direction!

I have printed some food safe prints for a friend couple of times now. Nozzle is stainless steel, Filament is natural HIPS. Stainless & HIPS are both food safe materials (if not mixed with color pigments). After the print, you need a clean surface. HIPS can be smoothed in an Acetone-Bath. Simply put it in for 10-15 min and you'll have a glossy finish.

HIPS is very easy to print in an enclosure and the resulting product is fairly stiff and durable. It's also temp resistant up to 90-100°C. So it's dishwasher safe.

Do not inhale acetone vapor, wear respiratory masks that filter out voc like acetone vapor.
