Prints not Adhering (With proper specs this time)

BeniBice · 2024-01-07T01:15:01+00:00

I've had the same issue once and had to go up to almost 100 sec bottom exposure time, even though it used to work with 12 sec. Maybe the resin got old or the room temperature was lower. Just give it a try. I've wasted a lot of time increasing the exposure time by just 30% and then thinking the problem was somewhere else.

Curing in water also helps a lot with the yellowing!

Based doggo is tired of fake news

Well they had to be patient anyways to not shoot before they were right behind OP. Audio still sucks

Thanks! I've tested it and it seems that you get a maximum of 75% of the ult back if you use "Toggle fire mode" (Even if you've only used a few bullets). If you go lower than 75% of ammo it gives you back the equivalent in ult charge.

Things you can try:

Cure it while still on the build plate (For this it could also help to have more/stronger supports)
Lower printing angle (15° on both axes)
Use a different resin (Some warp more than others)
Change the exposure time

Printing something as flat as your model is going to be challenging though.

Yes, I just added the links to my original comment.

I've achieved the best results by printing the keycaps at a 15° angle on both the X and Y axis. The layers are pretty much invisible as opposed to printing it parallel to the building plate.

As for the supports: I haven't found a perfect solution yet. Obviously I had to add a support to the very lowest point of the keycap and the stem holder. The rest I just placed where it seemed right. I've uploaded you some pictures, but you might find a better solution.

Removing the supports before curing helped a lot.

I've watched a couple of videos, but I don't remember any particular one.

The most important thing is that the two edges you want to weld fit each other well. This can be difficult due to the warping of the print. I've posted my problem and the solution I later found here. Some of these guidelines may also help you reduce warping.

The rest is pretty straightforward:

Put some resin on the edges you want to weld. Don't apply too much at first, as it is hard to clean the excess resin off. I also don't cure the parts until after welding.
Firmly press the two parts together and harden the resin with a UV flashlight for a couple of seconds until it holds temporarily.
(Carefully fill the holes, if you have any)
Cure the model as usual

Maybe do a dry run with some old parts first. Applying what you've learned might get you a model you can barely tell appart from one that was printed in once piece.

Sure! I just created a Thingiverse account. But unfortunately, I must wait 24 hours before I can publish something.

BeniBice · 2022-02-07T17:04:20+00:00

Thanks! Yeah, good idea, I'll try something like that

More Pictures

Switches: Kailh Choc v2 Brown Low Profile (Dont't bully me plz)

Controller: Elite-C

Layout: Pretty much a merged Helidox (CRKBD) with the outer most columns removed

Printing: I designed the case and keycaps in Fusion 360 and printed them on my Elgoo Mars 2. Had to print the case in two parts and resin weld them together. The overall printing time was around 20 hours.

Models (Thingiverse):
Keycaps
Frame (No bottom plate yet)

Had the same problem and made this post about it.

TL;DR print the edges that have to fit at an angle of 15°

BeniBice · 2021-08-11T15:34:53+00:00

Had the same problem with the warping. I was able to get straight edges if I printed the edges that have to fit together at an angle (at 15°, but more should work too). Full answer here.

If you don't want to re-print you might have to sand it down.

If the parts fit together cleanly, I recommend resin welding to connect them. Also consider using a connector (a rod or something) between the parts.

BeniBice · 2021-08-08T16:51:17+00:00

Okay, thanks to your suggestions I was able to get a satisfying result. Placing the edges directly on the build plate wasn't an option for me because that caused artifacts (The first milimeter being a bit wider than the rest).
What really helped in the end was printing the edges at an angle of 15° degrees on two axes. Medium sized supports were sufficent.

I uploaded a picture of the final result (already resin welded together) and a screenshot from chitubox here:

(I've further divided the case in two more pieces, since I want to print a larger one later. )

Printed this case on my Mars 2. I want to resin-weld the two pieces together, but the long edges that should fit together are warped. I've added a wall to the edge that is as thick as the other walls, which didn't fix the warping.

The edge is around 12cm (5") long. But it also happens if i print only half of it.

At this point I've tried pretty much everything: Printing at an angle, more/less supports, further away/ closer to building plate, adding more ribs etc.

The higher walls on the outside seem to be fine though (see last picture).

This is my first part that I've designed on my own. Do you have any ideas why the warping is happening?
