What your process engineer actually checks
Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.
A materials engineer on the line
Questions on ferrite content, flowability, recyclate ratios, or HIP response? A materials engineer answers directly — not a contact-form bot. Most replies in under 4 hours, NDA standard.

Unedited feedback from customers who reorder High density Polyethylene (HDPE) Natural Pellets - 2 lbs.
★★★★★
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.

COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
