Tough 1500 V2 prints

Hi -

Yes, that was printed in standard resin. These issues I have been experiencing I well documented in this forum already. Support did initially assist but the problem was never resolved. The end of it was always either geometry on my orientation of the part.

I suspected issues with my particular machine as I have some other issues as well as hinges failing about a month after purchase. Granted, I did receive a set of replacement hinges which I am still to install.

Aside from these issues, printing with Tough resin ALWAYS fails at firstā€¦ then I have to click ignore for the machine to proceed. Formlabs did give me a free cartridge to try and find the problem but we have had no luck. I tried everything they suggested and asked me to do, but the problem persists.

I have two build platforms, standard one and flex one. These layer lines are visible regardless of which platform I use. Sorry for the rant, but my frustration is spending almost $10 000 on this setup (not including a ton of resin and tanks) and have not been able to print a single part I ended up giving to a client. I mostly now print just to get an idea and then outsource printing.

I printed the same part flat on the build plate again nowā€¦ taking your advice and letting it dry out over night. Will cure it tomorrow and see.

Hi @leonhart88

I will try to print the test parts from this link:

This should give me an idea whether I am just not great as SLA printing or whether there is indeed an issue with the machine. They are huge though and reducing the size lead to me having to re-do the supports which defies the purpose of this test :thinking:

The part I printed yesterday and let out to air dry", warped even before curing.

thanks!

These are not the results I get when printing closures, never seen a layer shift like aesthetic on any Form4 prints Iā€™ve made so farā€¦

Have you tried designing bracing against the warping? I had some issues with parts warping over time with sun exposure and did some trail and error with embossed bracing in my design, this worked perfectly over time.

I agreeā€¦ this does not seem normal which I why I have been trying to determine from the start whether this is a problem on my machine.

When possible I do, but in this case with a total thickness of 8mm for the entire device, there is simply no space for ribs.

May I suggest you emboss the ribs outward? This has done wonders for me in the past and you donā€™t need much, sometimes 2mm can be enough and it keeps the space in the enclosure the same and even a bit more in in the embossing locations.
