3dprintingscanning

Summary

Introduction

Assignement: design and print one object, 3d scan and print the object that you scanned.

Learning path

3D printing

I want to project something usefull but little enough to be printed in short time
These are the ideas: an holding glass for the bed of my son, a cover for my garden lamp, a stuff for my old car.
I decided to proced with two object: the stuff for my car and the cover lamp.

The stuff for my old car: - Simple design - Little objects = small printing time - Problem: thin object that need a brim base to be printed correctly

The cover for my garden lamp - Some usefull measure of the lamp that i want to cover with a diffusor system - The sketch of the project - The final design with solidworks: various versions - And finally 3d printing and it’s problem

3D scanning

I used inect sensor with skanect to perform various scan: people, object and room. Then i decided to try to reconstruct a 3d model from a series of slices images of medical radiography using Osirix. After some funny test on my wristle radiography i found a tutorial (see instructable) where it was indicated how to rebuild a dinosaur skull from a series of dicom micro CT. I decided to follow this tutorial and print the euplocefalus skul for my son. This is the results.

Application to my final project

For the first assignement i want to design a special joint that is utilized to build some DIY geodetic dome. I want to reproduce i design that fit to my need of building a geodesic dome to cover my filter for my final project. Here the photo of that joint:

GeodesicJoint

My design ability is not so good so i attemp to approach this task using Openscad. In fact i think that with simple formula i can reproduce the design of the joint because it is based on geometric form that are repeated with simple simmetry. Here the result:
