Been running Nylon 12 GF for over a year from the start but trying Nylon 12 this week for the first time. While these parts were from the first two chambers at 100% fresh powder, I’m seeing major, unfinished looking,“burrs” along edges of parts. Never seen this before on Nylon 12 GF on the same pa…

Will give v5.1 a try on the next print. My concern with refresh that low is the point at which it gets “brittle”. Nylon 12 GF starts to for our parts below 60% refresh where we get more spring snaps. With the additional flex of Nylon 12 just will have to find that “push/pull” in refresh to get the s…

We carried out our own tests between the rates of 30%, 50% and also 70%. We didn’t notice a big difference, at least with our spring elements, so we said that we would use the lowest possible rate. I find it very strange that the bad edge should be the bottom edge, as the bottom edge is actually al…

We are close to a packing density of 30% for all our jobs. This chamber was just a test sample of different parts. We have run these chambers a hundred times at least with Nylon 12 GF in the same orientation with perfect results. Bad edge being down… was why I thought maybe that “outline pass” was …

So on further tests at a 40% refresh and the chamber temp turned down to zero offset from the original +0.75 tests and on the Default mode… I am still getting ugly fedge flashing and I can confirm it is on the lower edge (facing down) in the chamber. [Screenshot 2024-10-20 at 10.22.27 AM] [Screen…

I think I have already read from several users that they have lowered the bed temperature for PA12. The 0°C standard offset setting was too high for us. I just looked again and saw that the calibration print is only available for PA12. That means you couldn’t properly calibrate the PA12-GF to the c…

Yup, that’s what I thought :wink: Since Formlabs doesn’t provide any information about the many support articles or news about new articles, I occasionally look through all the articles to see if there’s anything new. You can definitely pick up a thing or two if you read through the articles. Even…

A lot of support people at Formlabs do not know what they have published on their own website… and some things on the website are self contradictory to support agent stated practices. To be honest I’ve derived more value from website info than I ever did from their support agents, at least on SLA s…

Hi @LEADNAV , our services team has been discussing this and recommends using v5.1 settings, which should give you the best part quality outcome. If you are open to turning on Print Settings Editor , then you can create a custom setting that uses reduced “Perimeter Upskin Laser Powers” and “Perimete…

So it does look like I’m running hot, as I did not even see any orange peel on the cone test till the -2c. I think I am going to try -1.75 for the Chamber temp Calibration. [IMG_6358] Will run a X/Y scaling calibration now then I will try some of our parts with the Speed Optimized v5.1 settings. …
