Material removal · casting fill & solidification · AM distortion · confidence
Partimation runs the physics behind every process before you commit real material to it: verified material-removal simulation on the machining side, GPU fill-and-solidification simulation on the casting side, and a distortion trend check before a metal print goes to the build plate. Every result comes back with a confidence basis, not a bare number — so you know how much to trust it before you act on it.

The problem
A toolpath leaves stock the tool can't reach, or gouges where it can — and you find out only after real material is already clamped to the table and the cycle's already run.
A cold shut, trapped air, or a riser that freezes before the casting it's supposed to feed — discovered after the tool's already cut and the metal's already poured. That's scrap, rework, and a delayed ship date.
Mill it, cast it, print it — the choice gets made before anyone runs the physics, because running it separately for each process is its own specialist's job that most shops can't justify.
What you get
A voxel material-removal simulation runs the toolpath against the part's real stock model — reconciled cycle time, unreachable features flagged, leftover and gouge depth called out — before a single real cut happens.
A free-surface fill simulation predicts fill order, last-filled regions, and trapped-air risk; a transient solidification solver predicts solidification order and confirms risers actually freeze after the regions they're meant to feed. Live today inside Castimation.
A thermal-distortion trend check flags the shelves and overhangs most likely to curl into the recoater blade, and a support-volume scan ranks build orientations by how much support material each one costs you.
Every result carries a confidence value and a named basis — a published prior, a calibration built from your own shop's actuals, a deterministic rule, or a flag that it needs human review — and every solver is checked against analytic theory before it ships, not just tuned to look right.
How it works
Upload a model; Partimation picks the physics that applies — removal, fill, solidification, or distortion.
GPU-accelerated where it counts, on the same voxel grid the rest of the analysis already uses — not a rule-of-thumb estimate.
Every flag names the rule or model behind it, and whether it's a published prior or calibrated on results you've actually seen.
Weigh build orientations, rigging options, or a toolpath revision against each other before you cut a tool or pour a mold.
Pricing
One account across the suite. DFM and should-costing are unmetered; simulation is metered by GPU run, not by part.
EUR and GBP prices exclude VAT, added at checkout where it applies. Early adopters keep their price as the suite grows.
Run it your way
Sign in and run a simulation from any browser. We run the GPU compute, ship the updates, and keep your data yours — the shared model only ever learns from your own results to calibrate your confidence.
Aerospace and anyone under NDA can run the whole thing on their own hardware. Licenses and updates are signed files — it never phones home, so an air-gapped install stays air-gapped.
Specialist environment
Castimation is where fill and solidification simulation lives end to end — rigging, gates and risers, pattern and core tooling, casting yield, and cast-then-machine routing, all built on the same GPU physics described above. Same account, same cost model, tuned for the foundry.

FAQ
Two of the three are real solvers: voxel material-removal simulation on the machining side, and GPU fill plus transient solidification physics on the casting side. Fill returns fill order, last-filled regions, and trapped-air risk; solidification returns freeze order and whether the risers feed the regions they are meant to. The metal-AM distortion check is a trend indicator, not a build simulation, and is labelled as one.
The removal simulation reconciles cycle time against the real stock model, flags features your tooling cannot reach, and calls out leftover stock and gouge depth. Collision, fixture, and machine-envelope modeling are not part of that run and are not claimed for it. Verify the crash question in your CAM or on a dry cycle; what comes back here is what the cutter removes and what it misses.
The distortion check flags the shelves and overhangs most likely to curl into the recoater blade on a metal SLM build. Read it as a ranking of risky features rather than a build simulation: no residual-stress field comes back, and no compensated geometry comes back either. Use it to decide what to redesign or support beforehand, then prove the build itself on the machine.
Simulation runs on our GPUs in the browser — there is nothing to install and no workstation to buy. Pro includes 30 runs a month, Shop pools 150 across its 5 seats, and an On-prem license runs unmetered on your own hardware. Metering counts compute runs only: DFM findings and should-costing stay unmetered, so screening a part never spends a run.
