3D printers are usually the tool you use when you want a one-off quick prototype. However, a lot more and more, they’re being used to produce things in quantity. [Uncle Jessy] made a decision to try out the resin stacking technique in buy to swiftly produce lots of figurines on his resin printer. However, not everything went exactly to plan.

The technique is simple. The idea is to produce lots of copies of an object in a single continuous print on a resin 3D printer. To achieve this, the object is cloned lots of times, and scaffolding is created to allow the stacking of multiple objects on top of each other. This need to be done very carefully to avoid spoiling the geometry of the object, and similarly to support material, uses a lot 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. additionally tweaks and beefing up the scaffold improved things, and [Jessy] managed to print 93 figurines in a single operation.

It’s a beneficial 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.
