At the Open Sauce maker festival in San Mateo, a Tom's Hardware reporter found desktop UV printers from xTool, EufyMake and Morpho, a flash-cure resin printer from UC Berkeley and new FDM machines from Prusa Research, Snapmaker and Elegoo. The report shows how UV printing, an industrial technology, is moving to small businesses and home users.
Key facts
xTool O1 Omni costs 1,699 to 3,969 dollars
Five companies are shrinking 50,000+ dollar UV printers to desktop size
OpenCAL flash-cures a whole resin model in a few minutes
Open Sauce 2026 was the festival's fourth year, in San Mateo
Context UV printing cures ink with ultraviolet light to print photographic colour on almost any material placed in the machine, from flat graphics to textures a few millimetres high.
Which desktop UV printers were shown?
The report counts five companies trying to shrink UV printers, which have cost more than 50,000 dollars, to a size and price that small businesses can afford. Three were at the festival. xTool presented the O1 Omni, a four-in-one UV printer, priced from 1,699 dollars with a single UV head up to 3,969 dollars. A production-quality review unit is still awaited.
EufyMake, formerly AnkerMake, was first to market with the E1 but had supply chain problems after a very successful Kickstarter. Morpho, a startup led by former DJI R&D vice president Brett Wang, showed an open-source UV printer that is not yet ready for review. Most machines in this class are still prototypes or in crowdfunding.
What else was on the show floor?
Prusa Research showed the CORE One+ INDX next to the CORE One L, MK4S and XL. Snapmaker printed a fan-made speeder bike on its U1 toolchanger and presented its Full Spectrum project, which mixes four filaments using subdivided layers. Elegoo showed the Centauri Carbon 2. Unlayered 3D demonstrated a development-stage non-planar 5-axis FDM printer that tilts the head and rotates the bed to avoid supports. Positron 3D showed a printer that folds to 200 x 200 x 70 mm.
UC Berkeley students presented OpenCAL, an open-source resin printer that projects a whole model at once and flash-cures it in a few minutes. The special resin is to be sold commercially through Formlabs.
What it means
For industrial users this is mostly a signal to watch, not a purchase case. Desktop UV printing could eventually give small workshops coloured, textured parts and labelling without a 50,000 dollar machine, but the report says most devices are prototypes or crowdfunded, with supply problems already seen. Reliability, material range and service support are unproven. Flash-cure resin like OpenCAL is a research result with no stated production timeline.
Frequently asked questions
How much does the xTool O1 Omni cost?
Machines start at 1,699 dollars with a single UV head and go up to 3,969 dollars for the fully equipped version.
What is OpenCAL?
OpenCAL is an open-source resin printer from UC Berkeley that projects a whole model at once and flash-cures it in a special resin within a few minutes. The resin is to be sold through Formlabs.
Which companies show desktop UV printers?
xTool, EufyMake and Morpho exhibited at Open Sauce, and the report says five companies are attempting such machines.
