HeyGears UltraCraft Reflex 2 Max: large format and productivity in resin 3D printing
HeyGears has introduced UltraCraft Reflex 2 Max, a resin 3D printer that takes the Reflex family toward larger working dimensions. The declared build volume reaches 353.3 × 198.7 × 400 mm, opening new possibilities for large components or serial production.
The machine promises a productivity increase of 50% in specific applications. But the numbers need context: real performance depends on geometry, material, and the complete process.
- Build volume: 353.3 × 198.7 × 400 mm
- 2.42 times the volume of the Reflex 2 Pro
- +50% parts per cycle in footwear elastomer tests
- Declared tolerance: ±0.2 mm on 100 mm features
Nominal volume and actual volume
The geometric data of the build chamber does not always coincide with the space actually usable for each type of part.
HeyGears claims a volume 2.42 times greater than the Reflex 2 Pro. This comparison is based on the geometric dimensions of the chamber. It does not mean that every object with those external dimensions can be printed in any orientation.
Part height, support footprint, resin drainage and stability during detachment limit the actual space. For thin geometries, the surface exposed per layer and the forces on the component become critical.
A technical comparison requires the same parts, documented settings and identical washing and curing conditions.
Productivity: beyond the number of parts
The 50% increase in components per cycle is a significant figure, but it is tied to a specific application and geometry.
The test conducted by HeyGears concerns elastomeric elements for footwear. In this case, the machine accommodated 50% more parts than the previous configuration.
The result is relevant for repetitive production in the footwear sector. However, it remains bound to that specific geometry, orientation and settings.
Total time includes preparation, unloading, washing, post-curing and inspections. Without these data, it is not possible to translate the capacity increase into a direct reduction in unit cost.
The time for a single job does not depend only on the number of parts. The productivity of a department includes all process phases.
Precision: contextualizing tolerances
A declared tolerance requires precise specifications on material, geometry, and measurement procedure to be comparable.
Among the technical data, there is a tolerance of ±0.2 mm on features of 100 mm. Before comparing it with other machines, information is needed on material, sample geometry, orientation, post-curing, and measurement procedure.
| Factor | Impact on precision |
|---|---|
| Exposure | Direct dimensional variation |
| Temperature | Influence on resin shrinkage |
| Post-curing | Post-curing and deformation |
| Geometry | Different behavior on thick or thin parts |
In photopolymerization, dimensional differences arise from exposure, temperature, resin shrinkage, and post-curing. A good result on a sample does not guarantee the same variability on thick, thin, or irregular parts.
Catalog data is a starting point for designing specific tests.
Applications and usage strategies
The machine offers two main strategies: large single parts or serial production. They require different evaluation criteria.
The transition to a larger chamber opens two possibilities: producing large components or fitting more parts into one cycle.
For the large part, uniformity and deformation control matter. For series production, repeatability, support management, and post-processing prevail.
The choice of strategy depends on the final application. In the footwear sector, serial production of elastomeric elements has shown concrete results.
Conclusions
UltraCraft Reflex 2 Max represents a significant dimensional evolution in the Reflex family. The stated data offer promising indications but require validation on specific applications.
Nominal volume, productivity, and precision should be evaluated in the context of the complete process. The machine targets those seeking production capacity in photopolymerization, with particular attention to repetitive geometries or large components.

Q&A
What is the build volume of the HeyGears UltraCraft Reflex 2 Max?
The stated volume is 353.3 × 198.7 × 400 mm, equal to 2.42 times that of the Reflex 2 Pro. This figure refers to the geometric dimensions of the chamber and does not guarantee that every part of those dimensions is printable in any orientation.
Where does the 50% productivity increase claimed by HeyGears come from?
The +50% parts per cycle was observed in a test on elastomeric footwear components. The result is tied to that specific geometry, orientation and configuration, so it cannot automatically be extended to other applications.
What tolerance does the Reflex 2 Max declare?
The datasheet reports ±0.2 mm on 100 mm features. For a fair comparison, the tolerance should be contextualized with respect to the material, geometry and measurement procedure used.
Does the nominal volume match the actually usable space?
No. Part height, support footprint, resin drainage and stability during detachment limit the effective space. For thin geometries, the exposed surface per layer and the forces on the component also become critical.
Does the increase in parts per cycle directly reduce unit cost?
Not necessarily. Total time includes preparation, unloading, washing, post-curing and inspections: without these data it is not possible to translate the capacity increase into a direct reduction in unit cost.
