Quality of 3D printing versus injection molding (lemmy.ml)

Are consumer level 3D printers able to print plastic objects of similar quality to ones produced using injection molding? Or is 3D printing useful mostly for the prototyping stage before a design is finalized and a steel mold is produced for injection molding?

This is very good information.

To add another point, a few other differences: -Additive manufacturing (3d printing) can produce some shapes which are not possible using injection molding -Injection molding currently has access to a wider variety of materials due to its maturity (pelletized raw material)

Additive manufacturing (3d printing) can produce some shapes which are not possible using injection molding

Agree. I was just thinking about this last night. The model I'm currently making would have to be multiple sub-components without 3D printing. Having everything as one piece, but still with a lot of air gaps, makes the finished product stronger.

Injection molding currently has access to a wider variety of materials due to its maturity (pelletized raw material)

There are pellet extruders, but generally agree that there's a wider material selection available for injection molding.
