VoxelMatters has reviewed the ELEGOO Jupiter 2, a desktop resin printer with a 302 × 162 × 300 mm build volume that sells for EUR 899 in ELEGOO's European store. The reviewers praise the automated resin handling and report that most prints succeeded on the first attempt, but they find the slicer software less polished and have not yet tested long-term use.
Key facts
Build volume 302 × 162 × 300 mm, about 2.5 times the Saturn 4
Price EUR 899; bundle with Mercury Plus V3.0 wash and cure station EUR 953
16K mono LCD with 20 × 26 μm XY resolution
Reviewers say it costs less than a fifth of a Formlabs Form 4
Context Stereolithography here means an LCD-based resin process that cures liquid photopolymer layer by layer with light shone through a screen.
What does the Jupiter 2 offer for the price?
The printer combines a 302 × 162 × 300 mm build volume with a 16K mono LCD of 15120 × 6230 pixels, giving 20 × 26 μm resolution in XY. The light source is fully enclosed to avoid leaks and keep exposure even across the plate. ELEGOO sells the printer for EUR 899 in Europe, or EUR 953 bundled with the Mercury Plus V3.0 wash and cure station, which offers 360° curing.
How does the automation work?
A two-way pump links the vat to the supplied 2 kg resin bottle. It tops up the vat during a job, pumps surplus resin back and raises an alert when stock is low. Four force sensors level the platform at several points, and the vat is heated to 30°C to help resin flow and layer adhesion. A mechanical sensor detects film residue, empty resin and levelling faults. A camera with LED lighting feeds live view and time-lapse into the ELEGOO Matrix app, and the machine has Wi-Fi, 8 GB of storage and over-the-air firmware updates. Compared with the Form 4, it lacks an interchangeable vat, does not report the exact amount of resin left and does not identify the resin automatically.
What were the weak points in the test?
The SatelLite slicer detects the printer on the local network and calculates cost per part, but it is not always responsive. Support generation sometimes froze and forced a restart with lost work, and imported models appear off-centre on the virtual plate. Complex prints take more expertise than on Formlabs software. The doors must open almost fully to remove the large platform, so the machine needs space on both sides, and the power switch sits at the back. The first self-check once failed, then passed every time afterwards. A few failed prints involved very demanding models that were poorly prepared. Long-term use is untested.
What it means
For small and mid sized European manufacturers, a large-format resin printer under EUR 1,000 lowers the cost of entry for jigs, fit checks and prototypes, and the bundled post-processing keeps total outlay close to the machine price. The review is a short-term consumer test, so it says little about repeatability, material qualification or service life. Before relying on such a system for production tooling, a company would need its own validation runs and a plan for software stability and spare vats or films.
Frequently asked questions
How much does the ELEGOO Jupiter 2 cost?
It sells for EUR 899 in ELEGOO's European store. A bundle with the Mercury Plus V3.0 wash and cure station costs EUR 953, down from a EUR 1,110 list price.
How large is the build volume?
302 × 162 × 300 mm, about 2.5 times that of the Saturn 4.
What did the reviewers criticise?
The SatelLite slicer is not always responsive and can crash during support generation, and the printer lacks an interchangeable vat and resin recognition. The doors also need much side space.
