The LUHLUH Stellar Pre is a masked-LCD dental resin printer with a build volume of 211 × 118 × 200 mm, a 15120 × 6230 pixel high-temperature LCD panel, a 405 nm light source rated at 20,000 hours, and a maximum forming speed of 30 mm per hour in Z. It measures 354 × 310 × 577 mm, weighs 26 kg, accepts STL files and runs from Windows or macOS.

The published accuracy figure needs to be read carefully. Specimen tolerance is given as 30 μm, and it is worth noting that this is not the pixel size — the build area divided by the panel resolution works out at roughly 14 μm across the X axis, and 19 μm along Y. A 30 μm tolerance figure therefore describes something more useful than pixel pitch: dimensional accuracy on a finished specimen. Ask which geometry it was measured on and whether it applies before or after post-curing, since resin shrinks as it cures.

Chamber climate control is a substantive feature rather than a comfort one. Resin viscosity changes with temperature, and viscosity affects how cleanly each layer separates from the film and how consistently it exposes. A printer holding constant temperature and humidity produces comparable parts on a cold morning and a warm afternoon, which is what makes a validated parameter set hold across a working year.

Motion uses a high-torque closed-loop servo driving a ball screw on a double guide rail. Closed-loop control means the Z position is measured rather than assumed, which matters on a machine building a part 200 mm tall, one layer at a time.

Two things are absent from the specification, and both are consequential: Z layer height, and any list of validated dental resins. Both are covered below. Medigear.uk can arrange supply, delivery, installation, commissioning and operator familiarisation across the United Kingdom.

Additive manufacturing now sits alongside milling in most digital UK laboratories, and a resin printer covers the work that mills poorly or not at all. The manufacturer positions the Stellar Pre for implantology, restorative work, orthodontics, surgical guides, removable wax-ups and internal crown wax-ups, in denture processing centres and dental clinics.

Model production is the highest-volume use for most laboratories. A 211 × 118 mm build area holds several arches per run, and printed models support crown and bridge work, orthodontic set-ups and clear aligner thermoforming.

Surgical guides are where the validation question becomes acute. A guide directs a drill into bone, so dimensional accuracy at the sleeve and the material's mechanical integrity both matter directly to the patient. The guide resin's instructions for use specify validated printers, parameters and post-cure protocols, and those documents govern whether a guide produced on any given machine is within scope.

Removable prosthodontics draws on the same discipline. Denture bases and try-ins, splints and occlusal appliances all enter the mouth, which places residual monomer and full polymerisation squarely in patient safety territory rather than finish quality. The wash and cure steps are part of manufacturing the device, not tidying it up.

Wax-ups for casting and pressing round out the range, where dimensional tolerance and clean burnout matter more than mechanical strength.

Laboratory obligations apply throughout: MHRA registration for manufacturers of custom-made devices, GDC registration for technicians, resin conformity documentation and instructions for use, and traceability from resin batch through print job and post-cure to the finished device. COSHH assessment of every resin in use belongs in the same file.

A 16K panel across a working build area

15120 × 6230 pixels over 211 × 118 mm gives a pixel pitch finer than the quoted tolerance, so panel resolution is not the limiting factor on fit.

Climate control for repeatable parts

Holding chamber temperature and humidity steady keeps resin viscosity consistent, which is what allows a validated parameter set to produce the same result across the year rather than drifting with the season.

Closed-loop Z motion

A high-torque servo with position feedback on a ball screw and double guide rail measures Z position rather than assuming it, which matters across the hundreds of layers in a tall build.

A protective cover that does real work

Shielding the build from external light reduces stray polymerisation at the vat surface, which shows up as improved edge definition and fewer artefacts on fine geometry.

Odour handled inside the machine.

Built-in filtration addresses resin smell at source, which makes the printer more tolerable in a shared laboratory — alongside, not instead of, proper COSHH controls.

Open file input

STL input with Windows and macOS support keeps the printer usable from whatever design platform the laboratory runs.

A usable build height at a stated rate

200 mm of Z travel at up to 30 mm per hour puts a full-height build within a working shift, with shorter models proportionally quicker.

The LUHLUH Stellar Pre gives UK dental laboratories a masked-LCD resin printer with a 211 × 118 × 200 mm build volume, a 15120 × 6230 pixel high-temperature panel, a 405 nm source rated at 20,000 hours, a stated 30 μm specimen tolerance, closed-loop servo Z motion on a ball screw and double guide rail, chamber temperature and humidity control and built-in odour filtration, at 354 × 310 × 577 mm and 26 kg. It covers models, surgical guides, orthodontic appliances, denture bases and try-ins, splints and wax-ups. Three things need settling before it goes into clinical production: which dental resins the manufacturer validates for this machine, what Z-layer heights it runs, and what wash and cure equipment you will pair with it — none of which the data sheet addresses. The validated combination of printer, resin, parameters and post-cure is what determines whether a printed device sits within its material's stated scope. Medigear.uk can arrange supply, delivery, installation, commissioning, operator familiarisation and post-processing equipment across the United Kingdom.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

Dimensional tolerance on a printed specimen rather than pixel size, which is the more meaningful of the two. Dividing the 211 × 118 mm build area by the 15120 × 6230 panel gives roughly 14 μm per pixel in X and 19 μm in Y, so the pixels are finer than 30 μm and are not square. What determines fit is how closely a finished part matches its design file, and that depends on exposure settings, resin shrinkage and post-cure as much as on panel resolution. Ask what geometry the 30 μm was measured on and whether it is quoted before or after post-curing.

Not published, and it should be. Z layer height governs surface finish, print time and vertical accuracy, and it is one of the parameters a resin manufacturer specifies in a validated print profile. Ask for the available layer heights, the minimum, and the default for each supported material. Without it, you cannot compare print times meaningfully or check that a resin's validated profile can actually be run.

This is the question that governs whether the printer can be used for clinical work at all, and it is answered by resin manufacturers rather than by the printer. Dental resins are medical devices in their own right, and their instructions for use specify validated printer models and print parameters. A surgical guide, splint, or denture base printed on a printer and parameter set the resin manufacturer has not validated sits outside the material's stated scope, whatever the printer is capable of mechanically. Ask LUHLUH which dental resins are validated for this machine, and confirm it from the resin side too.

Wash and cure equipment, neither of which is supplied with the printer. This is not a finishing preference. A part comes off the build platform coated in uncured resin and only partly polymerised, and the wash and post-cure steps the resin manufacturer specifies are what deliver the stated mechanical properties and reduce residual monomer. For anything entering the mouth — splints, guides, denture bases, trays — an incomplete cure is a patient safety matter, not a cosmetic one. Budget for validated wash and cure units and follow the resin's protocol precisely.

No, and the distinction matters. The filter addresses resin odour inside the machine. Uncured methacrylate resins are skin sensitisers and require handling controls under COSHH: nitrile gloves, avoiding skin contact, adequate room ventilation, and a compliant route for waste resin and contaminated IPA. Obtain the safety data sheet for every resin you run, complete a COSHH assessment, and do not read an odour filter as exposure control.

The 20,000-hour figure refers to the light source. The masking LCD panel in front of it is a separate component and a consumable — it degrades under continuous UV exposure and is typically replaced well before the light source is. Ask for the expected LCD life in hours or prints, the replacement cost, and whether replacement is a technician or engineer task. On a masked-LCD printer that is a running cost worth knowing before purchase, not after.

Repeatability. Resin viscosity falls as it warms and rises as it cools, which changes layer separation and effective exposure. A printer that holds its chamber at a set temperature produces comparable parts regardless of the room, so a parameter set validated in February still holds in August. That consistency is what makes a documented, validated workflow possible rather than a matter of adjusting settings by feel.

Bench space for the printer at 354 × 310 × 577 mm and 26 kg, plus adjacent space for wash and cure units and for resin storage away from light. A standard electrical supply, room ventilation, nitrile gloves and a waste route for resin and used IPA complete the picture. Keep the area separate from where finished restorations are handled, since uncured resin transfers readily.

The printer is production equipment rather than a medical device, so its conformity marking relates to electrical safety and electromagnetic compatibility requirements — confirm which regulations the declaration of conformity covers. The devices produced are custom-made devices, carrying MHRA registration obligations and an accompanying statement, with technicians registered with the General Dental Council. Resin conformity documentation, instructions for use and validated print parameters must be held, with traceability from resin batch through print job to finished device. Warranty terms are set by the seller or manufacturer: ask the term, whether the LCD panel is covered or excluded as a consumable, and UK engineer response times.
