ELEGOO M1 Ultra vs Revopoint MINI 2

A miniature maker needs the folds in a small sculpted cloak to survive a resin print. Across the workshop, another project needs the shape of a metal fitting and the pocket inside it. MINI 2 concentrates on close-range small-object capture; M1 Ultra brings several laser patterns and infrared scanning to a more varied bench.

Quick decision: small-object specialist or mixed-use scanner?

Choose MINI 2 when small, accessible objects in a controlled indoor setup define most of your work. Choose M1 Ultra when those objects share your workload with larger parts, difficult mechanical surfaces, or accessible recesses.

Our M1 Ultra guide explains the capture modes and preparation steps to consider when small parts share the bench with larger projects.

Both use blue light, but their capture systems differ. MINI 2 uses blue structured light. M1 Ultra provides crossed, parallel, and single-line blue-laser modes plus NIR structured light. The distinction affects how you approach the object, not just the number displayed beside accuracy.

M1 Ultra vs MINI 2: key specifications

Blue structured light and blue laser solve different setup problems

MINI 2 is designed around working close to small subjects. A craftsperson reproducing a carved decorative medallion can keep the object on a table, control the lighting, change its orientation, and inspect the relief without rearranging a larger scanning station.

That is a useful specialization when most projects fit the same operating range. A stable support and careful positioning may matter more than having a wider set of modes that the work rarely needs.

M1 Ultra changes the calculation when the geometry or scale varies. Its parallel laser pattern provides a detailed capture option, crossed lines cover broader surfaces, and a single line gives another approach to an accessible channel. NIR offers a separate route for larger subjects.

Imagine a custom hand tool with an organic grip and a recessed mounting interface. Capturing the outside alone would leave the part of the model that controls assembly unresolved. M1 Ultra gives the operator different patterns to try around those features.

Optical access still sets a limit. Neither a close working range nor a dedicated recess mode lets a camera see behind solid material. Plan additional orientations and leave room to rebuild genuinely inaccessible geometry from measurements.

Judge the detail in the mesh, not the shared 0.02 mm number

MINI 2’s manufacturer-specified single-frame precision is up to 0.02 mm, while its single-frame accuracy is up to 0.05 mm. M1 Ultra’s manufacturer-specified blue-laser accuracy is up to 0.02 mm. Those matching digits label different measurements and should not be treated as a tie.

Accuracy describes closeness to a reference measurement; precision describes repeatability. Resolution or point spacing concerns the detail represented by the data. Volumetric accuracy concerns dimensional behavior across the extent of an object. None of those terms can be substituted for another to make a cleaner comparison.

For a small resin reproduction, ask for a downloadable mesh and view it without color. Inspect shallow folds, thin edges, and the transitions between raised details. Then view it at the size you intend to print, because scaling can change which imperfections matter.

A textured preview can hide missing geometry. Painted eyelashes or engraved lettering may be visible in the image mapped onto the surface even when the mesh cannot reproduce them. That makes plain shaded geometry a more useful starting point for a single-color print.

For a functional miniature component, add dimensional checks. A clean appearance does not establish that a locating pin or seating surface will fit. Verify critical features and allow for the printer, material, and finishing process.

Working distance, surfaces, and a comfortable capture setup

MINI 2’s working range suits an indoor tabletop arrangement. Its small body can be convenient for handheld passes around a compact object, but the complete setup still includes a compatible computer or mobile device and a suitable power arrangement.

M1 Ultra includes its battery and screen in the handheld unit. Its weight therefore represents a different equipment package from MINI 2’s scanner body. Compare balance, visibility, supports, and power as well as the bare numbers.

Working distance matters inside an assembly. A scanner may be able to measure a small object on an open table yet be awkward to position between nearby surfaces. Before buying for an installed part, consider whether the projected light and cameras can reach the feature while remaining in the appropriate range.

MINI 2 may require scanning spray for transparent, dark, or highly reflective objects. For a jewelry master or valuable collectible, confirm whether a suitable temporary treatment is acceptable. A glossy object can be small enough for the scanner yet still be an unsuitable untreated target.

M1 Ultra’s specified ability to capture many black and metallic surfaces without spray is relevant when preparation repeats throughout the day. It does not make glass or every polished finish straightforward. Tracking also remains separate: markers can help a smooth object provide recognizable references.

MINI 2 is specified for indoor scanning. Keep that environment requirement in the purchase decision instead of assuming a portable body makes it equally suitable for every location.

Software, speed, and preserving the details you captured

MINI 2 uses Revo Scan with supported desktop and mobile platforms. M1 Ultra requires a compatible Windows PC or Mac. Both can produce mesh files for downstream design and printing; their computer requirements and connection options are included in the main table.

Frame rate is only one part of the process. M1 Ultra’s blue-laser limits differ between wired and wireless configurations, while MINI 2 has its own structured-light maximum. A higher rate does not shorten time spent preparing a reflective surface, aligning a difficult underside, or repairing the model.

For small objects, processing choices can also remove useful information. Excessive smoothing may soften a crisp lip. Automatic hole filling may bridge a real opening. Preserve the original data, make edits on a copy, and inspect the specific features that justified the purchase.

A turntable can make repeated positioning more convenient when it suits the object and package. It does not guarantee that the underside or a hidden recess has been captured. You may still need to change the support, scan another orientation, and align the results carefully.

Exporting STL does not produce editable CAD features. If your next step involves changing a bore or adding a fastening point, use the scan as reference for the required modeling work. Our 3D scanning introduction explains those stages.

Which scanner fits your regular projects?

A dedicated small-object studio

MINI 2 is a focused choice for an indoor maker who consistently scans small ornaments, model masters, or accessible components. Assess the surface preparation and sample geometry before deciding that its specialization fits your materials.

A workshop moving between scales and materials

M1 Ultra is more appealing when the same scanner needs to handle a compact fitting, a larger housing, and an organic reference shape. Its value lies in having different capture approaches available as the next job changes.

Repeated engineering parts at a fixed station

If controlled desktop part capture is the broader requirement, compare the other candidates in our scanner buying guide. For another laser-based option, see M1 Ultra vs Raptor Pro.

Budget for the scanner and the small-object workflow

ELEGOO M1 Ultra · €1,599 / MINI 2 Standard · €929. Compare the full capture setup, including the host device, supports, and surface preparation your objects need.

Check exactly what the selected edition includes. A turntable, stable mounting arrangement, calibration equipment, and suitable surface preparation can matter more to repeated small-object work than an accessory chosen only because it is bundled.

Computer compatibility should be checked independently of scanner size. A compact device can still produce datasets that require substantial processing. Confirm the current software requirements for the desktop or mobile device you plan to use.

For fitted or redesigned parts, budget for CAD work after capture. For decorative reproduction, include mesh cleanup, supports, trial prints, and finishing. Choose a setup that completes your normal jobs without an unexpected second purchase.

Which scanner should you choose?

Choose MINI 2 for a consistent indoor small-object workflow with accessible geometry and manageable surfaces. Its close-range specialization is a clear reason to shortlist it.

Choose M1 Ultra for a more varied workshop that benefits from several laser patterns, NIR, and integrated wireless handling. That flexibility is most valuable when small details are only one part of the work.

Review the M1 Ultra package against the objects already on your bench, or explore the ELEGOO 3D scanner range. Choose the setup that preserves the features you will still care about when the print is in your hand.

Frequently asked questions

Does MINI 2 use blue lasers?

It uses dual-camera blue structured light. M1 Ultra uses dedicated blue-laser patterns as well as NIR structured light. The shared color does not make the technologies identical.

Do both have accuracy up to 0.02 mm?

No. MINI 2’s manufacturer-specified 0.02 mm figure is single-frame precision; its single-frame accuracy is up to 0.05 mm. M1 Ultra specifies blue-laser accuracy up to 0.02 mm.

Which should I consider for resin miniatures?

MINI 2 is a focused candidate for small indoor objects; M1 Ultra is relevant when the same workshop handles broader jobs. Inspect untextured sample meshes at your intended print size before choosing.

Can MINI 2 scan outdoors?

Its specification lists indoor use. Plan a controlled indoor setup and evaluate the actual surface rather than assuming portability changes the environment requirement.

Does a minimum scan volume guarantee fine details?

No. It describes an object-size envelope. Thin projections, deep recesses, surface finish, tracking, and processing still determine what appears in the finished mesh.
