I just purchased a Form 1+ 3 weeks ago. I couldn’t be happier with the quality!
Wanted to share the progress on a 1/6th scale statue I’m doing of The Tick, based off the new Amazon reboot and Peter Serafinowicz likeness
7hr print at 25 microns using the Form 1+ Black.
Looks fantastic! What kind of post did you perform on this print?
No post. I thought UV post was only for “castable” jewelry.
As for cleaning. I soak in alcohol for about 10 mintes. I wipe lightly with a paper towel while also submerged in alcohol. And I do mean “lightly”.
I take out the print from alcohol, touch it, try to bend it. I like it to handle like a PVC cast anime figure to use as a master.
After the alcohol air dries i touch and look for wet spots that might be uncured resin. Usually another 5 minute soak and shaking in alcohol.
Let the alcohol evaporate either blowing on it or air dry if there is no pockets for alcohol to accumulate
It’s a much quicker process than this typed explanation, but leaves no scratches with the plastic feel I’m looking for.
:Edit - it will feel slighty “sticky” After all that and light touch. As long as it doesnt look shiny. After a half day sitting indoors it will cure to exactly what I look for in a master.
Once it “cures” to that PCV feel. I store the print in a dark box. Wood or closet. Keeping the resting stress on the thickest areas of the print (wherever you think your model won’t bend over time).
My first prints were done for a cartoon figure the first 2 weeks I had my printer, using Makerjuice SF. This cheap resin is only recommended for large scale smooth prints. A large amount of sanding is recommended for MakerJuice. Plot your supports/build platform accordingly with this resin, as that’s where is deforms the most…
FormLabs black01 turned out freakin’ perfect though! Definitely using high quality resin for my future prints.
By ‘post’ I just meant post-processing, which you described perfectly. By ‘Master’ I assume this is the pattern, and you’ll now make silicone molds and cast another resin for the actual part(s). Correct? I’d be very interested in your workflow on that as well.
Correct! Yeah I must mean pattern. Still learning the terminology for this stuff. I’ll post some more pictures of the process. at 25 microns some parts are up to 14 hour print times
I’m having issues with getting parts to fit perfect without cutting away a lot of material with a hobby knife.
These two pieces have quite a bit of work to go.
Are you giving the part a fit tolerance? One opening should be slightly bigger than the other. If they are the identical dimension they won’t fit without carving.
For most things that fit together I give a 0.1mm tolerance. If you are giving it a tolerance, perhaps increase it if it is taking work to get them to fit.
Yeah. I might have to increase the tolerance, as you mentioned. It’s mostly the distortion that happens around support areas
This is after some scraping with a knife.
Edit: I’ll be printing the arms so that the supports don’t touch the seams/merging surface. Let you guys know how that goes in 9 hours
Form the look here, it seems like you have an organically curved surface that ostensibly mates to the opposite curved surface on the torso, indexed via a tapered square peg.
Something you might consider is minimizing surface to surface contact. It’s not important how much surface mates to the other part, just that their seam when viewed from outside is tight. One thing you could do is to leave a couple millimeter around the seam at the height of the current mating surface, but inset the rest of the mating surface so it does not come in contact with anything. Do this to both the bust and torso mate surfaces. This will allow much easier fitting. Also, the bumps from the supports might not be such an issue.
Looking great though!
Great suggestion. I’m going to give it a go on my next large scale print. Possibly do it it on the lower body parts within Meshmixer (to keep the scale and hollow)
Matches up much better. Unfortunately the suit doesn’t leave many options to hide the seams.
The head was just too complicated of a cut and supports too dense. Lesson learned.
I’ll be closing/sculpting the seams with sugru before casting.
