You remember that time you were yelled at by that German guy for putting putting peanut butter in the print mechanism? Yeah, that was hilarious. He was like, “SLA!! Schweinhund!! nicht meine Erdnussbutter!!!” and you were like, “wha?” while spraying a goat down with a water hose.
I’ll never forget that. It’s sad however that peanut butter doesn’t work in a standard, bolt-it-to-the-floor 3D printer. Maybe one day, but until then, you’ll have to settle with the standard materials and the standard operating procedures. If not… lets just say it thirty lashes with a week-old bratwurst.
Solid Concepts has your back in the mean time and the tips to help you along. Here they are.
- Avoid “treeing” parts
When multiple parts are connected, parts cannot be individually oriented.
- Pay attention to standard minimum feature size.
Keep features larger than 0.012” for PolyJet, 0.020” for SLA, and 0.030” for SLS.
- For free flowing artistic and architectural models we highly recommend using SLS White.
This strong nylon material starts out as a powder and doesn’t require support structures.
- Understand the difference between SLA & PolyJet.
SLA White is excellent for larger parts, PolyJet has the highest accuracy and better for smaller prototypes
- Make sure the edges of your geometry are connected.
If there is a gap between two surfaces they will build separately.
