As somebody who is a member of Techshop and a student of 3D printing and metal CNC, I feel the blog post title and content were dead-on accurate.

Like one of my friends says, "3D printing is great ... for bathtub toys," where you don't need structural strength or fit and finish.

The more I learn about 3D printing with plastics, the less wonderful it is to me. I really don't understand what the above posts are griping about.

Mentally, I've made a note to only use 3D printing for molds at this point.

If you have the time, I've seen people finish objects using bondo or some other materials and you can end up with a nice looking object with a good finish. Strength on the other hand seems to be as much art as it is science, printing objects in the right direction and picking the right settings to get it to go the way you need it. I've not had a chance to make any real molds myself, how well does it end up working for the finish aspect also?
