One A1 Mini, a stack of plates, zero babysitting

SwapMod is a physical plate-swapper for the Bambu Lab A1 Mini. After each print SimplyPrint ejects the finished plate and loads a fresh blank one from the stack, so the printer keeps going for as many plates as you set. Available as a pre-built kit or a printable DIY version, both fully supported.

What is SwapMod?

The clearing method

SwapMod is a mechanical plate changer from Swap Systems for the Bambu Lab A1 Mini. When a print finishes, it ejects the whole build plate and loads a fresh blank one from a finite stack, so your printer keeps producing parts unattended.

In SimplyPrint this is a cycle-dependent AutoPrint method: because the plate stack is finite, you set a max plate count (the default is 3) and AutoPrint runs that many jobs back-to-back, then stops cleanly when the stack would run out. SwapMod comes in two editions, both fully supported here: a pre-built mechanical kit and a printable DIY STL version.

What operators say

Print-farm operators in our 2026 feedback survey repeatedly named SwapMod-style automation a hidden gem for fleet capacity.

"We quadrupled our print-farm. Everything SwapMod-related is the hidden gem."

How SwapMod works in SimplyPrint

Set it up once and let the queue feed it. Connect your A1 Mini, turn on AutoPrint, pick SwapMod, set your max cycles, then queue jobs and walk away.

1. Connect and enable AutoPrint

Add your Bambu Lab A1 Mini to SimplyPrint and turn on AutoPrint for that printer.

2. Pick SwapMod and set max cycles

Choose SwapMod as the clearing method and set how many plates are in your stack (default 3) so AutoPrint stops before it runs out.

Frequently asked questions

SwapMod is designed for the Bambu Lab A1 Mini. Both the pre-built mechanical kit and the printable DIY STL version are fully supported in SimplyPrint.
As many as there are plates in the stack. SwapMod is cycle-dependent, so in SimplyPrint you set a max plate count (default 3). AutoPrint runs that many jobs back-to-back, then stops cleanly so it never tries to swap onto a plate that isn't there.
You need the SwapMod hardware. Buy the pre-built kit from Swap Systems, or print the DIY STL version yourself. Use code simplyprint-5-jbxa1 for 5 EUR off at Swap Systems. On the software side you just need SimplyPrint with AutoPrint enabled.
With manual clearing someone has to be at the printer to remove the part and start the next job. SwapMod swaps in a fresh plate automatically the moment a print finishes, and SimplyPrint starts the next queued job for you, so the A1 Mini keeps printing through the whole plate stack without anyone present.
Yes. SwapMod is driven by the SimplyPrint print queue: AutoPrint pulls the next job from the queue, prints it, triggers the swap, and moves on. Smart matching makes sure each job lands on a printer that can run it.
