We recently completed a project where the customer requested a tool modification.
Most people think that modifying means it requires machining. However, with our 3D printed tooling technology, we just printed an insert and post processed to the tool. No welding, no machining was necessary & the modification was completed in just 2 days at a significant cost reduction for the customer.
If it was an aluminum tool, this request would require welding and machining- resulting in a much higher cost and take at least multiple weeks. This is just one of the powers of 3D printing and tooling!
