Recycling Additive Manufacturing Powders

Any time your 3D printer is not up and running means that time and money are being lost.  Recycling additive manufacturing powders should not be the bottle neck of your 3D printing process. While conventional vacuum and conveying systems have capabilities of high rates, none of the standard screeners combined with these systems can come close to matching this rate. Furthermore, to even have any efficiency at all, most of the vibratory screeners require a screen mesh that is above the specified particle size.  At Elcan Industries, we are strongly against “cheating the hole” when it comes to efficient screening. We believe that your powder should be screened at the spec that it is originally listed for.   If the size should be less that 44 micron, then the screen should be 44 microns – not 53 or 61.

The Hi-Sifter Powder Reclaiming system is the latest development in the additive manufacturing processing market. Using a high energy approach, the Hi-Sifter is able to assist in recycling additive manufacturing powders by making fine cuts that match the spec.  It is capable of sieving at rates upwards of 400 lbs/hour at sizes as low as 44 microns. Dense metal powders flow seamlessly through the screen mesh due the to stratification process that occurs inside the sieving machine. The Hi-Sifter allows for a much cleaner powder and far less downtimes between builds.   Many installations are successfully screening at 15 microns using the Hi-Sifter.   This screener is extremely capable!!

The Hi-Sifter is constructed of completely polished stainless steel and has minimal non-metal contact points. This makes it perfect for precious metal powders being used in industries like aerospace and biomedical. It has the ability to be run in an inert atmosphere to limit the risk of potential hazards when sieving explosive powders like titanium and aluminum. The vacuum conveying system it comes with is also rated for explosive powders and has easy set up and clean out. The Hi-Sifter’s sleak design also makes changing powders and cleaning out the machine a quick and easy process.
