Description
The Elegoo Mars Pro is a compact 2019 resin printer, a reworked take on the original Mars. It suits beginners and anyone printing miniatures or master models: nothing to assemble, and manual leveling takes a couple of minutes. What sets it apart from the plain Mars is the carbon filter and the rubber gasket around the hood, which together cut the resin smell noticeably.
Build volume is 120×68×150 mm with a 5.5-inch 2560×1440 screen at a 47 μm pixel. The panel is color — Elegoo only went mono with the Mars 2 Pro — so layers need about 6 seconds, bottom layers 45 seconds, and Z speed tops out at 22.5 mm/h against 30–50 mm/h on the later 4K machines. Light comes from a 28-LED 50 W array at 405 nm. You drive it from a 3.5-inch touchscreen and print from USB only; it weighs 7.5 kg and draws 72 W.
Pros
- The carbon filter and hood gasket genuinely cut fumes (GeekDad, Electromaker), though you still want a ventilated room
- An MGN15 linear rail replaces the old profile guide: Z motion is smooth and near-silent, and the first Mars bottom-layer squeal is gone
- The LED array speeds curing — in a 1000-layer test it finished about 50 minutes ahead of the plain Mars (3DPT)
- Practically ready to print out of the box, with strong detail on delicate parts (Tom's Hardware)
- The aluminium vat holds 100 ml more and weighs less, and the USB port moved to the front
- Generous kit: gloves, masks, funnels, two scrapers, plus an external power brick you can swap on its own
Cons
- The color LCD is slow and consumable: 6 seconds per layer against 1.5–2.5 on mono, and owners report dead panels after roughly 18 months
- The plate is small even for 2019 — larger models have to be cut up (Tom's Hardware, MakeUseOf)
- Prints bond to the plate hard and are a chore to pop off, and a metal scraper chews up the finish
- Exposure needs dialing per resin: Tom's Hardware used 90 s bottom and 15 s per layer on dark colors, 70–75 s and 12–15 s on clear
It fits people printing tabletop miniatures, busts and small master models who want into resin for as little money as possible. Engineering parts and larger geometry run out of plate quickly, and washing, post-curing and waste disposal stay part of the routine.
Bottom line: a polished version of the first Mars, now discontinued and sold as leftover stock. It only makes sense at clearance pricing; if you want a machine for the years ahead, look at the Mars 5 or Mars 5 Ultra with mono screens, auto leveling and several times the speed.
