Blueprint Studio software from HeyGears
The HeyGears resin 3D printer operates in conjunction with the Blueprint Studio slicer and 3D print management software. This tool is applauded for its intuitive interface, enabling an approachable experience for all, especially those new to resin 3D printing.
Blueprint Studio allows users to perfectly slice models, craft support, and modify designs. One standout feature is the “One Click-Slice” capability, which automates tasks including arranging, positioning, repairing, adding supports, and slicing the object. Automating these tasks simplifies the 3D printing process and is particularly beneficial for beginners.
Furthermore, Blueprint Studio is an excellent solution for industrial-scale users who want to operate multiple Reflex 3D printers within a 3D print farm environment. The software’s print management function empowers the user to control multiple 3D printers and monitor them concurrently, providing live updates throughout the stages of 3D printing, curing, and washing.
Those who frequently operate with resin 3D printing are likely to recognise the apprehension that comes with unsuccessful 3D print jobs.

An Integrated Resin 3D Printing System
The Reflex Combo presents a comprehensive 3D printing and post-processing system, providing washing and curing equipment in addition to the 3D printer.
Cleaning the 3D printed parts post-printing is crucial to get rid of any lingering uncured resin, which can be injurious and result in sub-par curing. Commonly, liquid solvents like Isopropyl alcohol are employed for this purpose.
Using a distinctive method, the Reflex washing station initiates a turbulent flow within the wash tanks. This is achieved by making the entire tank oscillate, ensuring the cleaning solution thoroughly engages with the printed parts with sufficient force to eliminate any undesired residue.
When a component has been meticulously cleansed, it must then undergo ultra-violet light curing to solidify the resin further. Such a process stabilizes the material’s characteristics of the component, elevates its surface quality, and betters its precision and tolerances.
HeyGears’ Reflex curing apparatus greatly intrigued us. The apparatus’s chamber is capable of heating up to a whopping 80℃, thereby excelling in optimizing curing all across the component and eliciting an exceptional finish on the surface. The device also radiates UV light at a couple of different wavelengths, warranting various resin types to be effectively cured.
The UltraCraft Reflex delivered to us was equipped with a Pulsing Release Module (PRM). This optional enhancement that can be harmoniously integrated with the 3D printer aims to curtail the peeling force per layer by up to 50% through high-frequency oscillations. This led to accelerated 3D printing velocities and less need for support, thereby minimizing material usage. Nevertheless, our observation found that the module did little to significantly improve the surface quality relative to a standard resin tank. The HeyGears PRM can be acquired for $649 from its online shop.

Benchmarking the UltraCraft Reflex
Our engineering team conducted 135 hours of testing on the UltraCraft Reflex. This involved an array of 3D printed components designed explicitly to assess the 3D printer’s capabilities. Our evaluation began with the test file bundled with the system, a model representing the Blueprint Studio logo.
The resulting model delivered good surface quality. We were satisfied with the details of this part, notwithstanding some apparent artifacts from the supports. This test also validated the functionality of the standard washing and curing processes.

Consistency and repeatability are crucial for prosumers who desire to create identical parts in batches. To evaluate the repeatability of the UltraCraft Reflex, we 3D printed a small component 12 times in groups of six and compared their size to the original Computer-aided design (CAD) model. A mean deviation of 0.1 millimeters and a standard deviation of 0.05 millimeters signifies a satisfactory outcome.
The performance of this 3D printer surpassed that of others in the market. The overall mean deviation was exceptionally low, at 0.0215 millimeters, and the standard deviation was only 0.0160 millimeters. For a consumer-grade resin 3D printer, these figures are remarkable, indicating both outstanding accuracy and precision. Each test piece exhibited high print quality, with a smooth finish and no layer separation. However, post-processing did leave some marks from the support removal.

The UltraCraft Reflex sets itself apart with its remarkable 3D printing volume, which is considerably above market average for desktop resin 3D printers. The question is, can users 3D print components that reach the complete advertised dimensions?
We initially carried out a tower examination in order to check the declared Z-axis of 220 mm. The slicer from HeyGears limited the component to 219.9 mm, successfully 3D printing the tower to this size. It’s a common scenario for 3D printers to somewhat reduce their measurements, making this outcome a positive one for the UltraCraft Reflex.
Our tower section demonstrated no shift between various layers, boasting of a slick surface and decent angles. But, the base of the tower displayed a slight elephant’s foot. This is generally a result of inadequately adhering the initial layer and over-curing the first few layers.
Unfortunately, HeyGears doesn’t provide a way to tweak exposure controls. Consequently, we couldn’t adjust the exposure duration to minimize over-curing or to get rid of the elephant’s foot. Advanced settings can’t be altered, which could be a source of annoyance for skilled users keen on perfecting their 3D printed components.
Nonetheless, under normal circumstances, Blueprint Studio would automatically orient and provide support for models to elevate them above the build plate during 3D printing. Even though supports closer to the build platform might undergo over-curing to achieve better adhesion, this shouldn’t affect the ultimate component being printed. Hence, unless users manually set the model flush with the build platform, they are unlikely to come across similar elephant’s foot issues.
We also conducted a width test, which perfectly matched the advertised dimensions of 192 mm x 121 mm x 220 mm. However, as with the tower test, a slight elephant’s food was created. The model was also slightly warped after curing but possessed flat sides and no layer shifts.

For users wanting to produce parts with complex geometries, the ability to 3D print overhangs is essential. In our overhang test, the UltraCraft Reflex performed very well, achieving consistent overhang results up to an angle of 65°. This surpasses the average performance of most other resin 3D printers, with consistent layer curing and no peeling effect.
However, the overhang models were tossed around inside the washing station during post-processing, causing their edges to chip. The gyrating nature of the HeyGears washing station could pose problems for users wanting to produce models with sharp edges and delicate features. To alleviate this issue, users can add a protective shell in the Blueprint software. 3D printed around the part, this shell protects the model during post-processing.

Next, we evaluated for ‘capability.’ This principle, originating from the 1970s US automotive sector, employs statistical process control to gauge the appropriateness of the 3D printer for large-scale component production.
In this context, we 3D printed a certain design 150 times, selecting 16 random units and taking their measurements three times each. Based on these measurements, the UltraCraft Reflex delivered a process capability score of 5.79. This suggests that this 3D printer can fabricate precise components with minimal deviations from the desired size.
However, a process capability index score of 0.41 points towards inadequate precision. This insinuates that the 3D printer may have difficulties in ensuring consistency when dealing with extensive production batches.

The 3D printer was an admirable performer, creating a prosthetic that was not only easy to assemble but also strong and hard-wearing.
Engineers and prosumers often require the ability to perform reverse engineering or to create functional components, such as casings, typically made using injection molding. To evaluate a 3D printer’s capacity to fulfill these needs, we created an outer casing for a Nintendo Wii remote based on a 3D scan.
The 3D printing process was successful, resulting in a product with high surface quality and no observable flaws. The internal wall details were excellently rendered, and the two sections fit together seamlessly. The cleaning station and hardening unit performed excellently, ensuring no residual unhardened resin remained in the small openings or crevices.

A popular application of desktop resin 3D printers is the production of miniature models and figurines that possess fine details. To find out whether HeyGears’ 3D printer is a good choice for users targeting these applications, we 3D printed four different models with unique geometries. Given that each model featured small and intricate details, which would be easily damaged within the washing tank, we 3D printed them inside a protective shell. This is something we would recommend for most delicate models, given the rigorous nature of the part-cleaning process.
These test pieces highlighted the 3D printer’s ability to produce parts with fine details and clean surfaces. The parts were aesthetically pleasing, and certainly meet the requirements of users wanting to produce high-quality miniatures.
