This is a 3D-Printed Guard for the Bosch GWS 12V angle grinder. It is much more useful with a smaller guard like this so I designed one (never use without the guard - you don't want to get your little hands caught in there..)

 

 

You have to use a very high performing material to get a useful and safe part. Disclaimer: I printed  two of them to stress- test it. I would suggest for you to do the same and after properly printing + annealing the part try destroying it yourself :)

Pro-tip: Use metal cutting discs with carbide or diamond grain - they will not shatter.


 

Preferably use PA6-CF but most importantly from a reputable Brand (3dxtech, Essentium, Spectrum, AddNorth, Polymaker, Prusament etc.)

If you have no enclosure for your printer, try PET-CF. Same principles apply ⬇

 

0.6mm nozzle

max. volumetric Speed ~ 5mm3/s

Nozzle cranked to the max. eg 300°C (look at the TDS from Manufacturer)

Bed ~80-110°C

No cooling and no Fans active!!

Let the chamber heat up to 50°C before starting, if you have an enclosed Printer that is.


 

After printing let the part cool down a bit, remove and anneal in 70°C water for 15min (not longer). Afterwards let dry overnight.
