About DrUnknown

I am a materials scientist working as the Principal Scientist for PANalytical, a leading developer of X-ray analysis instruments. In addition to using my 3D printer to create customized sample holders for our instruments, I am developing techniques for the analysis of 3D printed filaments and 3D printed parts. Techniques that I am exploring include X-ray diffraction analysis of partially crystalline thermoplastics such as POM and nylon; X-ray fluorescence spectrometry to determine the chemical purity of filaments and the consistency of pigment additives; and computed tomography (CT) to measure the precision of internal features in 3D printed parts and to produce computer models from original pieces to use as the basis for printing reproduction pieces.
