Resin Stacking Proves Messy And Difficult

3D printers are typically the tool you use when you want a one-off quick prototype. However, more and more, they’re being used to produce things in quantity. [Uncle Jessy] decided to try out the resin stacking technique in order to quickly produce many figurines on his resin printer. However, not everything went exactly to plan.

The technique is simple. The idea is to produce many copies of an object in a single continuous print on a resin 3D printer. To achieve this, the object is cloned many times, and scaffolding is created to allow the stacking of multiple objects on top of each other. This must be done carefully to avoid ruining the geometry of the object, and similarly to support material, uses more resin in the process.

[Uncle Jessy] experimented several times, but ran into multiple issues with the process when trying to print out some small Magneto figurines. An initial experiment using a raft failed when the print fell off the build plate. With the raft removed, the second print failed as the scaffolding didn’t print quite right. Further tweaks and beefing up the scaffold improved things, and [Jessy] managed to print 93 figurines in a single operation.

It’s a useful technique if you want to print a ton of models on a resin printer in as short a time as possible. However, expect to spend plenty of resin as you refine the technique. You’ll also need a big wash tank to clean the prints during post-processing. Video after the break.

    1. These horrible thumbnails are a great filter for crappy content, but I am sad whenever a youtuber whose material is otherwise good pays too much attention to metrics and begins experimenting with these awful things as clickbait.

      1. As the thumbnail doesn’t actually affect the content of the video, and as you’re obviously a person of high moral standing, I’m sure you can overlook the humble artist’s attempts at gaining an audience.

      2. Look, if your going to object to eye-poppingly great one-stupid-trick videos Youtube is doomed.

        I didn’t watch the video because the description sounds like they set up any given new job on a home-gamer resin printer. Eye popping was icing on the not going to watch it cake.

        1. Im getting into selling painted miniatures and the vid was actually helpful, stacking models keeps you from having to get up in the middle of the night to set up prints, you just press start once and you get the entire nights worth of printing, it does require some trial and error but in the long run it is actually good. Youtube thumbnails don’t show the entire content of the video.

    2. Yep. I’m not clicking either. Some YouTube channels are just garbage regardless of the content. This is a good example.

      Maybe we’ll get some better articles, the writers might get better pay, and maybe they’ll hire a copy editor now that things are changing hands. I really don’t get why people don’t run articles through a word processor before publishing. LibreOffice is FREE, and I’m sure it’d catch the typos even in the farewell announcement.

      1. +1. If the content creator didn’t think it was worth writing a coherent document, their content is not worth our attention.

        I don’t want to turn these comments into a cesspool of negativity, and I *do* want to keep seeing hacks from beginners… but we have to be honest and provide feedback about how the hacks could be improved. If our voices are heard often enough, clickbait videos won’t get articles. The articles that *do* get written will all have metric units, and the source code/files will be readily available.

        A man can dream :-)

    3. Same for me. Stereotyped simian youtubers annoyingly put themselves between the subject of interest and the camera. I guess in some years everybody will be gesticulating like that IRL, like in a Chaplin movie where everybody is a Charlie Chaplin / Louis de Funès hybrid. A vision of horror. At that point I will probably take refuge in a trimmed VR world with low-poly, quiet people.

    4. Yeah, it’s a real turnoff whenever I see these. It feels manipulative and while it may have been effective for engagement once, today it seems transparent and desperate. I wish this trend would end.

  1. I fail to see the advantage of stacking figures vertically. Isn’t it easier to print one layer of densely stacked objects, then postprocess that when the next layer is printing, which would decrease the total process time, the size of the process tank and the waste material (scaffolding). Or am I missing something?

    1. I suspect you are underestimating how much cleanup and the time that requires before you can set it going again, along with as Dan suggests leaving it running longer between interventions – If you only have to interact with each one once a day, twice a day – something you can easily do in your waking/working hours because its printing a large run overnight and finishes the second one by mid afternoon etc that is a great deal more time you can spend doing other work like the post processing clean up on the previous runs parts.

    2. Speaking as a machinist, Foldi-One is right. Unattended run time is gold. I could run a part every 15 minutes, or run 32 of them over 8 hours. The latter is much less work, and the machine can be productive while I’m sleeping.

      1. It’s always nice to have something ready waiting for you, but it always boils down to whether you can trust the process not to self destruct or burn down your workshop whist unattended. Some sort of verification or automatic cut off switch is always preferable.
        In theory it should be possible to set up cameras or laser scanners to check against the design, but in practice, creating the software would be pretty tricky. I wonder if one of these cheap-ish ai self training camera moduals might be an option, ie. If it doesn’t see the expected image within x time window it stops the print. I’m guessing here but I’d say the resin is probably not conducive, but if it were or it could be made to conduct, measuring the resistance curve over time could be a great way to monitor print quantity.
