DeutschExciting news! Vosfox Medical has successfully 3D printed their first mould for blister or tray production. With this development, they can now offer the possibility of making at least up to 100 blisters at a low cost. For higher volumes, a metal mould is needed.
First, we designed the mould. The mould must fit tightly in the mould block so no air can escape, resulting in badly formed blisters. The team used the SLA printer to print the mould insert, then washed and cured it.
Very small holes in the mould must be placed to ensure that the trapped air can be removed by applying a vacuum during the forming process. These holes must all be connected to the one hole in the mould block where the suction is applied. Drilling by hand with ultra-thin drills resulted in breaking three drills. We must optimize this process to reduce the number of broken drills. Using a column drill should solve this.
The printed part fit perfectly in the mould block, and with similar temperature and pressure settings as with metal moulds, we produced perfect blisters that were formed and sealed quickly.
This innovation in 3D printing opens up new possibilities for low-cost, low-volume production for our customers.
