Looprint automates serial production on Bambu Lab printers using G-code post-processing

For many FFF printing jobs, the workflow does not end at the printer after the last layer, but at the printing plate. Once printing is complete, the component and any residues must be removed before the next job can be started. For users who want to produce identical parts in large quantities, this manual step is a bottleneck.

The free Looprint tool from Nicki Anderson addresses this issue. The software aims to automatically switch to the next run after a print is complete. The approach takes advantage of a well-known effect: after cooling, the connection between the print and the plate often loosens more easily because the component and the print bed expand at different rates when heated. Looprint therefore waits for the print to cool completely. The print head then performs defined movements to push the loosened part off the plate. This clears the surface and allows the next print to begin.

Technically, Looprint works as a post-processor for already sliced data. The tool accepts G-code or 3MF, removes the original start and end code, puts the print in a loop, and inserts cooling and ejection logic between repetitions. The process repeats as many times as specified by the set number of loops. The prerequisite is that the model is sliced with brim. Looprint removes the usual prime line because it cannot be reliably repelled. The brim takes over the function of material preparation and is ejected together with the component.

The process involves slicing a single part in BambuStudio with brim and exporting the G-code to the PC. A web interface handles the conversion; parameters such as the number of repetitions and confirmation of the brim are set there. Looprint lists the A1, A1 Mini, P1, P1S, X1, and X1C series as compatible. For P and X models, the door must remain open, otherwise ejection may fail.
