Design Guidelines

3D printing gives you a lot of freedom of shape, but there are a few guidelines that help you design things that print nicely!

3D scanning programs

photo to 3D programs and services

There are some 3D scanning options. Reconstructme is the most impressive, because it works almost entirely real-time, creating a 3D model of things you view with a camera. http://reconstructme.net/

There's also a web-service called http://www.123dapp.com/catch). Use it to take pictures on trips, with your family, or of favorite places and turn them into a personal sculpture.

The many options for designers

Apart from 3D printing existing models, there is nothing like having an object that you've both designed and printed yourself. It means you're starting to master the skill of changing the material world around you, starting out with just thoughts, an idea. There are many choices of design software, but they can be very different in many respects. We've ranked the following list primarily from easy to hard and from affordable to expensive (secondarily).

Tutorials

  • How to simplify a mesh (by Pieter Bos)
    Sometimes a mesh has too much detail and the printer will slow down in an attempt to include every detail. If you reduce the complexity of very detailed models, it will allow you to print them much faster. This video tutorial by Pieter Bos view here will teach you how to do this.
