To branch off our in depth review topic…
We are unable to get Nylon 12 GF to successfully print on a Fuse 1.
Curling of the extra thick surface armor at the start of the print/chamber will not allow it. It’s a crap shoot if it will succeed and after 4-5 print jobs attempted in a row, in the past 48 hours…all failing…we’re not getting anywhere or closer to any true resolution from the support team.
Support is aware of this issue and are supposedly going to release a firmware update to help make this possible…but as of now I’d say it is false advertising to expect that the standard Fuse 1 can currently succeed in printing Nylon 12 GF repeatedly.
I wish this was an issue with our particular machine, that they could identify, but right now that does not appear to be the case and I think they overshot a bit in promoting Nylon 12 GF, on the standard Fuse 1.
Only thing left for us to try, possibly, is to move the parts way further up the build chamber to allow more buffer between the start of the prints (lots of wasted powder) and or try and run all “fresh” powder versus the current 50% refresh rate we are trying. Nylon 12 GF is suggested at a “spread” of 30%-50%…and wander if we could actually get successful prints again by going 100% fresh powder.
Reason I think these things might make a difference, is that with some buffer in the print chamber added at the bottom, we were getting just one to two prints to fail at the start…lowering the parts today to the bottom of the chamber in Preform (still within allowable boundary)…almost all the parts were curling and failing at the start. Also, we were able to get a few jobs to succeed more at the start of all this…so wandering if the 50% refresh rate advertised is anywhere close to being actually possible…
Neither of these things, if they make a difference, would be optimum due to the excessive waste of powder to make it all work.
We are looking to give this system another solid week in attempting to actually/consistently print Nylon 12 GF before looking at other options.
Our last resort will be to clean out the system and load regular Nylon 12 in to see if it makes a difference. However, even if it does, it is unacceptable as we were sold this machine in the confidence and need to print in Nylon 12 GF.
As of this weekend, it looks like we may be getting our hands on the new Sinterit Lisa X soon to be able to compare these two systems side by side.
Fingers crossed one of these two systems work, as I still have hopes in SLS for our production parts.
