First time user with GreatAccentor here. we just received our 3L and printing with Tough2000, obviously on the beta profile at the moment.
Some findings, in no particular order:
-
None of the quickstart guides i found mention that you are supposed to squeeze the bite valve a few times to ‘losen it up’ the first time you use it. so filling the 3L tank was very slow
-
same goes for just pouring your resin from the container into the tank.
-
the progress bars on the printer and dashboard dont match. the dashboards percentage is the number of layers printed out of the total, the bar on the printer is the time progress. so on a job thats wide at the bottom and thin at the top, i had the printer showing 75% and the dashboard 50%
-
using the default support settings, but they are very hard to remove. snapping them off by hand is not gonna happen. you will need the cutters to cut up the raft and supports and remove them in small sections, beeing carefull not to cut yourself on the sharp edges
-
even after washing (ive tried IPA and TPM), and post cure (120 minutes, 80c), the prints remain quite sticky, and even get matt where you touched them. this seems to get better in the next day(s). not sure if thats just a tough2000 thing (it is mentioned in the material info that it can take up to a week!)
-
oh, when leveling the printer: it was instrucing to turn 1 leg in a certain way, but that leg was already at its limit. so had to turn all the others the other way instead. may be a button to change the instructions ?
-
print speed: it looks like its doing a VERY slow pulloff, then a fast up for 1cm, fast down 1cm, then a slow down… why the fast bits? the whole procedure takes longer then the printing of the layer
-
i cant seem to find the remote printing option? may be thats not available on the 3L yet ?
-
Preform: may be im spoiled with things like Lychee slicer, but having to use only 1 piece of software that can also do hollow, add drain holes etc is convenient
while i do have some mixed feelings about the 3L in general, i am well aware its a brand new printer and startup issues are to be expected. and i have full confidence that Formlabs will fix most if not all of them in upcomming updates.
