HeyGears upgrades capabilities with the UltraCraft Reflex RS The UltraCraft Reflex RS has been designed to cut 3D printing times, increase part quality, and simplify professional-grade production.  Notably, HeyGears has boosted 3D printing speeds in its newest offering. Capable of 3D printing at 27 mm/hour with a layer height of 50 μm, the Reflex RS incorporates the company’s latest Dynamic Motion Algorithm 3.0. This reportedly increases production speed by 33%, requiring an average of just 4.5 seconds for each layer.  Users targeting professional applications value high repeatability and reliability. The Reflex RS’s C5 grade Z-axis module meets these requirements by maintaining stable layer thickness and repeat positioning accuracy. According to HeyGears, this feature ensures layer positioning errors do not exceed 2 μm.  Customers choosing resin 3D printing often do so to produce high-precision parts with intricate details. The Reflex RS is a great option for these requirements. Its 33 μm XY precision and ±16 μm, combined with an 8K resolution and 405 nm light wavelength, unlock significant advantages in fabricating accurate parts with smooth surface finish and fine details. Our extensive testing validated these capabilities, successfully producing minute details and meeting the tight tolerances of functional components. The HeyGears Reflex RS build plate.

Despite this, HeyGears’ latest system is more compact than the company’s previous iteration, ensuring the Reflex RS easily fits into most benchtop workspaces.      For newcomers to resin 3D printing, calibration can be an intimidating process and a frustrating delay to production. HeyGears’ Reflex RS features extensive automation functionality, making it ideal for those wanting quick and easy 3D printing straight out of the box. Notably, the Reflex RS is equipped with a floating-screen system that automatically levels the 3D printing platform with a precision of 0.15°, effectively eliminating gaps of up to 240 µm. This feature enhances accuracy, prevents layer detachment, and reduces the risk of print failures.  Additionally, the resin filling and heating system autonomously maintains the tank’s resin level, refills as needed, and heats the material to the optimal printing temperature. It can raise the resin temperature from 10°C to 22°C in just 20 minutes, ensuring consistent heat throughout the printing process. This helps prevent material inconsistencies, guaranteeing reliable results across various environments. Furthermore, automated zeroing and precise bed leveling minimize the need for manual adjustments, enhancing overall efficiency.            HeyGears set a high bar with the impressive build quality of the UltraCraft Reflex, and the new RS model does not disappoint.

A streamlined post-processing workflow  The Reflex RS Combo offers a full end-to-end resin 3D printing workflow spanning printing, washing, and curing.  Washing a resin print after printing is essential. Solvents like isopropyl alcohol are commonly used to remove uncured resin, as this toxic, viscous liquid can pose health risks and lead to poor curing, ultimately affecting part quality. HeyGears’ Reflex washing station stands out with its unique turbulent flow process. Instead of using a conventional impeller, it gyrates the entire wash tank from its base, preventing laminar flow and ensuring the cleaning liquid effectively removes residue. However, the gyration can cause delicate models to collide with the tank walls, potentially leading to damage. This risk can be minimized by printing a protective case around the models.  Once washed, the 3D printed part should be cured in UV light to harden the resin further. This helps to enhance its mechanical properties, improve surface quality, and optimize tolerances and accuracy.  We were impressed by the curing unit. It possesses a sleek design and user-friendly interface with a rotating knob to facilitate easy selection of curing options. Its chamber can heat up to 80°C, unlocking effective curing and an impressive surface finish. UV light can also be emitted at two different wavelengths, ensuring thorough polymerization and allowing different resins to be effectively cured.  Our engineering team also tested HeyGears’ Pulsing Release Module (PRM). Using a compressor, this optional add-on delivers bursts of high-pressure air to generate high-frequency vibrations that gently separate the film from the printed model’s surface. These vibrations reduce peeling force by up to 50% per layer, enabling faster printing and requiring fewer supports, ultimately lowering material consumption. The PRM is available for $490 on HeyGears’ online store.    Our testing found that the PRM does not significantly improve surface quality compared to the standard resin tank. However, it does offer faster print speeds and reduced material consumption. A comparison in the Blueprint slicer showed a 26.5% decrease in print time and an approximately 12.5% reduction in material usage, which is great for users looking to print continuously.

Blueprint Studio software As with its predecessor, the Reflex RS is not compatible with third-party slicing software. Instead, it is controlled by HeyGears’ proprietary Blueprint Studio platform. This allows users to slice models, generate supports, manipulate parts, and modify designs. It also includes a print management feature, which can manage multiple Reflex systems and operate 3D print farms.    With a user-friendly interface and streamlined operation, Blueprint is a great option for resin 3D printing newcomers. Its “One-Click Slice” feature significantly simplifies the slicing process, allowing users to repair, orient, support, layout, and slice models at the touch of a button.   Returning hours after starting a print job only to find it has failed—and wasted valuable material—is a common frustration in desktop 3D printing. Blueprint Studio’s printability analysis helps mitigate these risks by evaluating a model’s support structures and identifying potential issues like cupping, thin layers, and unsupported projections. Our testing confirmed that this feature effectively predicts and analyzes problems that could lead to print failures, resulting in a 98% success rate. One downside is the inability to change resin type once slicing has started, requiring users to start a new slice project—an inconvenient and time-consuming process. While the workflow is easy to navigate, it lacks advanced features, limiting options for experienced users. For example, Blueprint does not allow customization of exposure settings, peeling speed control, or bottom layer count adjustments. Despite these minor shortcomings, we view Blueprint as a great, easy-to-use software that streamlines resin 3D printing and enhances the production of high-quality parts.

Benchmarking the Reflex RS Our engineering team conducted extensive testing to benchmark the Reflex RS and evaluate its performance against the advertised specifications. We began by printing the test file included with the 3D printer, a model of the Blueprint Studio logo. This part came out well. It was free from defects and completed the washing, drying, and curing steps without issue. All features and fine details were clearly visible, representing a good start for the Reflex RS. 3D printed test file. Photos by 3D Printing Industry. Repeatability is crucial for professionals looking for dependable prints or when producing batches of identical parts. To evaluate the Reflex RS’s consistency, we 3D printed a test model 12 times and measured each print against the original dimensions. High-quality 3D printers should achieve an average deviation below 0.1 mm and a standard deviation under 0.05 mm. 3D printed repeatability test parts. Photos by 3D Printing Industry. The Reflex RS performed outstandingly in this test, surpassing market standards and many competing models. No dimensional anomalies were detected, attesting to the high precision of the 8K LCD screen. Across all axes, the average deviation was 0.0179 mm, significantly lower than the 0.05 mm benchmark. The standard deviation was 0.0084 mm, well below the 0.25 mm target. These results are very impressive for such an affordable desktop 3D printer, confirming its exceptional accuracy, precision, and reliability.

The UltraCraft Reflex RS boasts an expanded build volume, which exceeds the market average for desktop resin 3D printers. Unfortunately, BluePrint Studios’ setting restrictions prevented the tower from reaching the RS’s maximum 230 mm height limit. The software downscaled the model to a 228 mm height, a negligible difference of 2 mm, which was disappointing nonetheless. On a more positive note, the quality of the tower test was impressive, with consistent layers and minimal defects. The parts’ 25.01 mm (x) and 24.98 mm (y) measurements further demonstrated the great accuracy offered by the Reflex RS. 3D printed tower test model. Photos by 3D Printing Industry. Our perimeter test was more successful, with the slicer accepting the exact 222 mm x 122 mm dimensions advertised by HeyGears, confirming that users can fully utilize the RS’s print bed. Once again, 3D print quality was high, with flat, even sides and only minor warping post-curing. These results successfully validate the X and Y dimensional accuracy of the Reflex RS. 3D printed perimeter test model. Photos by 3D Printing Industry. Parts with unsupported overhangs often pose challenges for resin 3D printers, but are a common feature of advanced models with complex geometries. Our testing confirmed the Reflex RS’s ability to handle overhangs. It achieved consistent results up to a challenging 65° angle, surpassing the average performance of most other competing systems.  We 3D printed two overhang test models, with and without the PRM. A line was visible at the top of the PRM part, likely caused by the model’s large surface area, which required a larger peeling force. When the PRM wasn’t used, a similar defect occurred around ¼ of the way into the print job, again caused by the high peeling force. Despite this slight blemish, both tests performed well with consistent layer build-up, confirming the RS’s ability to successfully handle overhangs. We recommend using the PRM when printing parts with overhangs or fragile details. 3D printed PRM (left) and regular (right) overhang tests. Photos by 3D Printing Industry. Many customers who adopt resin 3D printers do so to exploit their advantages for small and precise parts with tight tolerances. Is the Reflex RS a good option for these critical applications? To find out, we 3D printed two small, functional nut and bolt models The Reflex RS exceeded our expectations, successfully producing 1.25 mm and 1.0 mm pitch threads. Both models were printed to a high standard, displaying excellent detail and surface finish. As the thread pitch became finer, we noticed an increase in assembly resistance. However, both assemblies worked as intended, confirming the RS’s ability to handle functional parts with tight tolerances. 3D printed 1.25 mm (left) and 1.0 mm (right) nut and bolt models.

Next, we tested for ‘capability.’ Tracing its origins from the 1970s US automotive industry, this concept uses statistical process control to assess the ability of the 3D printer to mass produce parts at high volumes.  We 3D printed a model 150 times, randomly selecting 16 prints and measuring each three times. These figures will be used to calculate the process capability, a statistical measure that assesses how well a manufacturing process can consistently produce parts within specified limits. The minimum process capability will also be measured. This takes into account decentring, which reduces repeatability.    Any score above 2.0 is very good for these calculations, while anything under 1.33 is below acceptable. The Reflex RS achieved a process capability score of 3.43, demonstrating its ability to consistently produce accurate parts with minimal variation from the target size. Its exceptional minimum process capability score of 7.96 further highlights its impressive precision and low likelihood of defects. This makes the Reflex RS an excellent choice for professional users targeting high-volume production. 3D printed capability test parts. Photo and image by 3D Printing Industry. Testing 3D printing applications  Next, we tasked the Reflex RS with a range of hobbyist, prosumer, prototyping, and end-use applications. The use of resin 3D printers in the medical and dental industries is growing, thanks to their ability to produce durable, accurate, and customizable parts close to the point of need. To assess the Reflex RS’s suitability for such applications, we first produced a 3D printed mandible. This part featured impressive surface quality, with no layer lines or defects. 3D printed mandible model. Photos by 3D Printing Industry. We also 3D printed an arm cast, highlighting the ability of additive manufacturing to provide patients with custom-fit devices tailored to their unique anatomy. The Reflex RS performed admirably once again. The complex, large-scale geometry came out perfectly, with minor defects easily resolved with extra fine sanding paper. Disclaimer: This part is for demonstrative purposes only. Users will need to use skin-safe resins for any applications that come into contact with the body, this is not currently available from Heygears. 3D printed arm cast. Photos by 3D printing industry. Engineers, designers, and prosumers may also consider the Reflex RS for reverse engineering or producing functional parts typically made through injection molding thanks to its high accuracy. To evaluate its capabilities, we 3D printed an Xbox controller shell. The print was largely successful, though a minor layer inconsistency defect, caused by excessive peeling force, slightly disrupted layer alignment. Despite the PRM being in use, it failed to prevent this issue. However, the 3D print quality remained high, with precisely defined mounting points and bolt holes and minimal support artifacts, making the shell ready for use on an actual game controller. 3D printed XBOX controller case.
