3D printed samples

|
|
==================

|
When the sample shape is too complex so that a backing mold cannot be made to [cast the photoelastic sample](https://git-xen.lmgc.univ-montp2.fr/PhotoElasticity/Main/wikis/molding-urethane) it is still possible to directly 3D print it. 3D printing is not simple and it is even worse when you have to do it with a photoelastic material making sure there is no residual stresses. That is why you should not expect this way to make photoelastic samples to be the ultimate one. It is good if you want to work with hard material (high loading) and that you can afford expensive samples. Also if you want to rapidly prototype a photoelastic sample and if your measurement accuracy is not too high, it still worth. In this section we go more into details about this method and the different options.
