The machine behind Machine No. 001

Print Lab

Every printed gram of the Vulpa H750E comes off one machine: the Vision Miner 22 IDEX. Dual independent toolheads, a heated chamber, and vendor-tuned profiles for the full engineering-polymer wall — it's the reason a 27 kg hydraulic excavator can be printed in ULTEM, PEEK and carbon-filled PPS instead of machined from billet.

Three ways to run a plate

every print card picks its mode automatically
Standard plate on the 22 IDEX bed
Standard

One job, one tool. The chamber-bound polymers (ULTEM, PEEK, PPS…) run one part per plate so layer times stay honest — small parts pair 2–3 to keep each layer cooling right.

Mirror

The IDEX party trick: T0 prints the driver side while T1 prints the passenger side, flipped, simultaneously. Two dried spools, one overnight run, a matched pair by morning.

Duplicate plate on the 22 IDEX bed
Duplicate

Quantity-two parts print twice in one job — both toolheads running the same geometry side by side. Sprockets and rollers come off the machine in pairs.

Vision Miner · seven years of successful prints

First layers are where prints die. Warp lifts a corner in hour two, the part peels, and a full spool's worth of hours goes in the bin. One thin coat of this on the plate — it activates as the bed passes 60°C — and the part grips flat through the warp-prone hours instead. If a part wears a ⚠ warp risk flag on the parts board, this is the first line of defense.

Who's behind the machine

the origin story, and a decade of lessons you can ask questions
Why we built our own printer · 16:58

Drone parts that cracked and warped under real load started a hunt for materials that don't — PEEK, ULTEM — and no accessible machine could print them. So we built one. Patrick and Rob tell the whole story.

Ask VM Assist

Our decade of high-temp printing — PEEK, ULTEM, carbon-fiber nylons, all the lessons that cost us failed prints to learn — distilled into a personal assistant you can ask anything about 3D printing.

Give me some tips to make this carbon-fiber nylon print the best it can.
What's the best way to dry my filament?

It won't have every answer — but it'll usually hand you real insight.

Full disclosure: Small Iron's builder is one of the two people in that video — Vision Miner is his company, and this excavator is the 22 IDEX's 27 kg stress test.
