Printing a prototype propeller for my Lightnin lab mixer

Friday 8th September 2017

An example of how handy the ability to print in 3D can be. The worn-out stainless propeller costs $300 to replace. But the size and pitch of the blades is not ideal for the work I do. I print them in PLA plastic, this enables experimenting with different sizes and pitches. When one works well then I can have a stainless one printed at These plastic propellers are surprisingly durable and it was easy to print one the with a hole the exact size needed, it fits tight on the shaft and never moves.
