"Hey Guys, Jordon from Tempus 3D here, I wanted to show you our manufacturing process for MJF and highlight some post production options we use right here in beautiful BC Canada.

We start out in Magics which is our slicer of choice. I'm orientating the part this way for 2 major reasons, the first is that we need to allow heat to escape the prints, so ideally large holes face upward. The second reason is that with MJF printing the bottom surface will always have a better finish. Because this is a art piece that will mostly be viewed from above, I wanted that section to be facing down. There are a lot of other considerations to take into account to prevent various defects like in any type of manufacturing.

Here you can see the part being extracted from the powder. The huge advantage to powder based printing is that we don't need to print any supports like in FDM or resin. We recapture most of the unused powder to be recycled back into the next build. we currently run 80% recycled powder.

After the unpacking station comes the blasting, we use a modified wet media blaster to remove the bulk of the remaining powder. The advantages of wet blasting are reduced dust and longer media life.

We do also dry blast the parts to get all the nooks and crannies, you can see I'm moving the gun constantly because the friction can actually burn the parts and cause damage if you arent careful.

This would would be a final part if the customer chose a raw finish, but we usually dye the parts to look like this, I can't show you the dye as its a proprietary system I have designed and built inhouse.

One of our newer offerings is Vapour Smoothing, we use this AMT PostPro SFX. Vapour smoothing greatly increases the finish qualtiy aswell as making the part more water and chemical resistant. For parts that are too big for our machine we borrow the capabilities of our HP partners who run much larger machines.

This is a finished part with black dye and VS, it offers an even black glossy finish and a perfect base for Cerakote or paints.
