Form 3 is dead

Yeah, their replacement part costs can be ridiculous. There’s no way that board is $1,200 to the user. I worked for a company that applied two 40% markups on parts, which is a crazy high profit margin. If FL is doing the same, that would mean that the board cost them $600. No way. They make thousands of these. I’d be very surprised if the motherboard cost them even $200.

I guess when you’re the only supplier of repair parts you can charge whatever you want.

Thank you. I’ll check it out. So far the info I’m reading about fixes for this isn’t reassuring. I’m getting very disappointed with FL service. Hard to feel like making any new “investments” with them if they can’t offer support for their equipment. Buying a entire new printer is not effective support.

Thank you again for sharing.

The resin overflow is the Form’s Achilles Heal. All the other ingenious engineering on these and overflow handling is nonexistent and results in disaster. We had two Form 3s die in this manner. After major leakage, even after thorough cleaning, they just never worked well again. At least the Form 2 had a little drip edge with a ledge that directed overflow away from electronics. That just doesn’t exist in the Form 3 and any spills will result in the machine pretty much ruined.

Our spills had a similar issue with the mainboard. Fortunately, these were still under warranty.

of course, the caveat here: Do not, under any circumstances, let the tanks leak! :smiley:
Tank handling is extremely critical.

I’m in the same boat as of yesterday. The printer isn’t turning on but the green LED on the motherboard lights up. The only solution from support was to buy a replacement for 1200€… so not a solution at all. Did anyone get somewhere with some kind of potential fix? Any help at this point is welcome.

Trying to diagnose the problem myself further, I took apart the motherboard and the little daughterboard that has the CPU on it, and there was resin in like every little crevice, and it seems like some resin had solidified on the pins where the daughterboard and motherboard make a connection. So I can’t say for sure why my printer stopped working in the first place, but that was probably the problem since I think the resin is insulating, preventing the connections from making electrical contact. I ended up getting the service to replace the printer with a refurbished one…

But yeah I think Formlabs could have done a better job of isolating the electronics from possible resin leaks.

Maybe an after market “drip tray” of some sort

Same thing just happened after a white resin leak, Our team did a full deep clean, using a shit ton of 100% IPA for the bigger parts and washing all the electronics in the Form Wash IPA for 2 minutes at least each. The cables where the biggest problem, the resin stuck inside the connector, and every time I cleaned the tip more would come out as I let it dry, after many washes (IPA on both sides of the connector, then jumpers wire header inside, twist the jumper a few times and then pull out) the resin finally stopped blocking the connectors and they where able to pass current again.

it was a very deep but gentle clean, I poured IPA and every where i saw white and rinsed and repeated until all the resin was removed. Of course, if the resin was conductive it would have been much worse of an outcome.

One thing to note is that the PCBs become very fragile with the years, you can easily rip the components with their pads and traces off the board if you are not gentle, use Q-tips and towels with discretion, it is always better to wash electronics and most other parts with the Form Wash or many rinses of IPA than it is to scrub the electronics. Remember to take out the battery out of the motherboard before you wash.
in particular, there is a small board on the bottom back side to the right if you are looking from behind, under the stepper motor for the wiper. It only has a connector and an optical encoder. It is very important unscrew and remove this board before you reassemble the bottom cover on the body, because its not easy to align the two, and when you try to do it you will snag on the cable for that connector and rip it of the PCB with its pads and caused a big headache, the screw for it is on the other side so even after you assemble the bottom you can still screw back in without trouble. This will not work if their are other sources of damage, the reason the printer did not turn on in this case was because the resin was blocking the connectors, if there are other issues it might not turn on after the clean.
