SLS Up Close

Here is what some of our SLS powders look like up close. The "scattered" images simply means I spread the powder out real thin to be able to see the particle size distribution better.

You can see that most of the major particle sizes are about 80 microns or so, but there is large range is size distribution. This may or may not be a good thing.

You can see from the partcake samples how the material as conglomerated. We should be able to develop a process to re-grind and/or refurb the partcake material on site to virgin material specifications.

Looking at the HST materials, you can see the glass fibers in the mix. The is a large range in fiber length as well, from 100 microns or so down to just a few. Just looking at the pciture I would guess it is about 10% glass in the formulation.

I have also included material on a 100's of an inch scale to confim my scale calibrations as well as a picture of a 4 thousandths shim. For reference 4 thousandths of an inch is approxiamtely 100 microns.

This HST sample gives us a good idea on formulating new fiber reinforced materials.
