Hello,
We’ve had the Form 3+ for less than a month at my job and am honestly getting buyers remorse given how bad our experience with the Tough 1500 resin has been. It has many issues, one of which it deforms heavily under at low temperatures, but most importantly, it the worst dimensional accuracy of any resin or filament I’ve ever used. Advertised by Formlabs on their “Dimensional Accuracy Report” says they have maintained a -0.05" average dimensional tolerance on 100mm features, whereas I’m getting 2.15mm oversized after post curing in the Form Cure. Yes, you saw that right, it’s over 40x worse accuracy than what Formlabs is advertising it can hold.
This is not only a bad look for Formlabs but is also a bad look for myself as I’ve had to adamantly advocate to get a Formlabs printer in our department, and to have it fail this terribly, I mean I might as well just eye ball these part sizes with a dremel I could probably do better this is really terrible and I’m going to have to ask Formlabs for refund materials unless they can recommend a resin that can print to what they say they can.
Anyways I’m just posting this to let anyone wondering whether to buy this material to please stay far far away unless you’re just doing single piece models as it’s too inaccurate to be used in any multi-part assemblies period.
