Every part we sell is made in one building in Lismore, Minnesota, on 140 Bambu Lab printers that run around the clock. There is room in the building for 900, which is the plan, but here is how the 140 work today.

The order comes in

Orders land in a queue that is sorted by what is already printing. Popular parts are usually on the shelf, so an order for a grease gun holster and a pry bar holder is a pick-and-pack job that goes out the same day. Anything not on the shelf gets added to the print list.

The queue

Each printer runs a plate of parts, and a plate is set up to fit as many of the same part as it can. Small parts like can inserts go a dozen to a plate; a Kubota ROPS bin is one to a plate and runs most of a day. The long prints get loaded in the afternoon so they finish overnight, and the morning is spent pulling plates, checking parts and reloading. By mid-morning most of the farm is running again.

Checking parts

Every part gets looked at before it goes on the shelf. Magnets get pressed in, springs get installed, and anything with a fit issue goes in the scrap bin rather than the box. Layer lines are normal on a printed part; a gap between layers is not.

Packing and shipping

Parts ship from the same building. Most orders go out within a day of the parts being done, which works out to 2 business days from the order to the box leaving. Print files are different: those are a download and you have them the minute you pay.
