Plug-and-mill installation with no compressor required. A 60,000 rpm German spindle, 13-tool automatic changer, Smart Servo anti-vibration and MillMind remote monitoring — built for 24/7 dry production in the clinic or the lab.
The UP3D P55D is an air-free 5-axis dry milling machine engineered for continuous production. A German electric spindle reaches up to 60,000 rpm while a Smart Servo system actively damps vibration for micron-level precision. The air-free, plug-and-mill design removes the compressor entirely — faster installs, lower facility cost and a quieter, more compact footprint. A 13-tool magazine with 0.3 mm micro-carving and 0.6 mm extended burs, 90-degree vertical milling and a high-concentration ionizer keep detail sharp and the chamber clean across zirconia, PMMA, wax, PEEK and soft CoCr.
What the P55D actually gives a production lab, in plain terms.
A German electric spindle runs to 60,000 rpm with Smart Servo anti-vibration, holding micron-level precision on complex cases.
Plug-and-mill installation. No compressor to buy, house, or service: cheaper install, quieter room, smaller footprint.
Automatic tool change across 13 tools, including 0.3 mm micro-carving and 0.6 mm extended burs for fine detail.
Watch tool life, receive reminders, and supervise production from a PC or mobile — built for unattended, around-the-clock runs.

The honest version. A dry mill is the right machine for a large share of labs and a poor fit for others — here is which is which, before you spend the money.
All three are air-free 5-axis dry mills sold by US Dental Depot. The real decision is disc changer versus footprint and price — not raw spindle speed.

All three mill the same materials: Zirconia · PMMA · wax · PEEK · composite resin. Material range is not the deciding factor between them — the disc changer, footprint and installed power are.
