Manufacturing gears with non-standard parameters, especially when it is a low-volume batch is a headache for engineers and managers. It is difficult to find a production partner that can produce a small batch of gears within a reasonable timeframe, especially when you have a unique set of parameters and tooth profile. In order to produce unique gears, you need to set up the equipment, find the fixtures and the workpiece. All this leads to a huge cost for a seemingly simple part. But modern technologies suggest an simpler way out - metal 3D printing. The production time for this gear is 4 days, 1 of which was the day to set out the scope of work, and 2 were the weekend. As a result, the item was sent to the customer on the day the order was paid.

The material is stainless steel powder PR-03H17N12M2 for 3D printing by JSC "Polema". The powder fraction is 20-45um. The layer thickness is 50um.

The gears are made on an AM3D Pro metal 3D printer. Printing time: 50 minutes.

There are 4 M4 threaded holes. The threads were part of the 3D model and were completely printed out of metal. No post-processing was involved.
