- Xometry typically uses anchors on flat Nylon12 and PC10 parts in the form of small, round pillars connected directly to the baseplate. These anchors must be completely removed and the underlying surface made flush to the part prior to shipping.
Checking tip wipe heights
- In order to reduce surface defects, be sure to check your tip-to-wiper height using the Stratasys procedure.
Turning on “No Grow Support” in Insight on every part
- This can save time on printing many parts. Insight will still grow support when necessary, but this will prevent it from growing support when it’s not necessary.
Keeping PC-10 parts out of the bath
- Xometry uses SR-100 support instead of PC support. We found that it is easier to work with.
- Even though SR-100 is soluble in the sodium hydroxide bath, we try to avoid using sodium hydroxide as much as possible since it degrades the PC-10 in the form of cracks and brittle features.
Frequency of Bath maintenance
- Turning over the bath on a regular schedule will maximize the efficiency of your support removal. To reduce support material removal times on large parts, baths should be preemptively turned over.
In order to maintain accuracy, tips should be replaced after 400-500 in³. To avoid print color inconsistencies on machines being turned over, tips should be labeled with current tip odometer and last material colors used. When turning over machines in the same material and different colors, purges or a tip replacement may be necessary. No ASA Blue tip should ever be used with any other color - the Blue is un-purgeable!
- Make sure everything will actually print.
- Be sure that you are orienting for strength and appearance. Ask us if you have any questions.
- Layer height has an equal effect on strength as orientation or geometry.
- Don’t use metal tools for support removal!
- But if you have to, avoid touching the part with the metal tool to avoid damage.
- Before removing material from the part, make sure you are not ripping off the part itself.
- Remove support material with holes that are less than a quarter inch.
- When placed into a bath, make sure it’s a fresh bath.
