The EnvisionTEC Micro Plus Hi-Res: A Deep Dive into Detail

The EnvisionTEC Micro Plus Hi-Res is a 3D printer that caters specifically to applications demanding extreme precision and detail. It’s not your everyday desktop FDM printer; instead, it leverages DLP (Digital Light Processing) technology to create objects with incredibly fine resolutions, making it a go-to choice for industries like jewelry, dental, and audiology. Let’s take a closer look at what makes this machine tick.

Detailed Specifications:

• Technology: DLP (Digital Light Processing)
• Build Volume: 45 x 28 x 100 mm (1.77 x 1.1 x 3.94 inches) - This is a deliberately small build volume, optimized for detailed parts, not bulk production.
• XY Resolution: 30 µm (0.0012 inches) - This is the key factor for high-resolution printing.
• Dynamic Z Resolution: 25 µm to 100 µm (0.001 inch to 0.004 inch) - Layer thickness can be adjusted to balance speed and resolution.
• Light Source: High-power LED with UV Projector
• Material Compatibility: Specialized EnvisionTEC resins (e.g., E-Dent 400, E-RigidForm, RC-31) - Material selection is limited to EnvisionTEC’s proprietary resins, offering specific performance characteristics.
• Connectivity: Ethernet, USB
• Software: EnvisionTEC Perfactory Software Suite
• Machine Dimensions: 330 x 260 x 530 mm (13 x 10.2 x 20.9 inches)
• Weight: ~17 kg (37.5 lbs)
• Power Requirements: 100-240V, 50/60 Hz

Usage Tips for Optimal Results:

• Resin Selection is Crucial: The Micro Plus Hi-Res relies on EnvisionTEC’s specifically formulated resins. Choose the correct resin for your application (jewelry casting, dental models, functional prototypes, etc.). Read the material data sheets carefully.
• Orientation Matters: Part orientation is critical in DLP printing. Minimize the cross-sectional area of each layer to reduce stress on the part and supports during printing. Think about the part’s geometry and how it will peel away from the build platform.
• Support Generation: Use the EnvisionTEC software to generate robust, yet easily removable, supports. Proper support placement is essential to prevent warping and ensure dimensional accuracy, especially for overhanging features.
• Leveling the Build Platform: Ensure the build platform is perfectly level. This is critical for first-layer adhesion and overall print quality. Follow EnvisionTEC’s recommended leveling procedure.
• Cleanliness is Key: Keep the resin vat and optical surfaces clean. Contamination can negatively impact print quality. Use appropriate cleaning solutions and lint-free cloths as recommended by EnvisionTEC.
• Post-Processing: DLP printed parts often require post-processing, including support removal, cleaning (using isopropyl alcohol), and UV curing to fully harden the resin. Follow EnvisionTEC’s recommended post-processing procedures for each specific resin.
• Temperature Control: Maintain a stable and appropriate ambient temperature in your printing environment. Some resins are more sensitive to temperature fluctuations than others. Consult the resin data sheet.
• Software Familiarity: Invest time in learning the EnvisionTEC Perfactory Software Suite. Mastering its features for support generation, part orientation, and print parameter adjustments will significantly improve your results.
• Resin Shelf Life: Be mindful of the resin’s expiration date. Expired resin may not print properly or may result in parts with degraded mechanical properties.
• Ventilation: Ensure adequate ventilation in your workspace, especially when handling resins and cleaning solvents. Wear appropriate personal protective equipment (PPE) such as gloves and eye protection.

Evaluation:

Here is an evaluation of the EnvisionTEC Micro Plus Hi-Res on the specified criteria, each rated out of 10:

• Print Quality: 10/10 - Exceptional detail and surface finish are the hallmarks of this printer.
• Build Volume: 4/10 - Deliberately small, optimized for high-resolution, small parts.
• Printing Speed: 6/10 - Not the fastest, prioritizing quality over speed. DLP is generally faster than SLA, but smaller layers and resolutions slow things down.
• Material Compatibility: 5/10 - Limited to EnvisionTEC’s proprietary resins, but those resins are specifically formulated for high-performance applications.
• Bed Adhesion & Leveling: 7/10 - Critical, requires careful attention to detail but generally reliable when properly set up.
• Reliability: 7/10 - Requires regular maintenance and care, but generally reliable when used within its specified parameters and with proper materials.
• Ease of Use: 6/10 - More complex than a basic FDM printer. Requires familiarity with DLP printing and the EnvisionTEC software.
• Firmware and Software: 7/10 - EnvisionTEC’s software is powerful but has a steeper learning curve than some simpler 3D printing software packages.
• Connectivity Options: 6/10 - Basic Ethernet and USB connectivity are adequate, but lacking advanced features like Wi-Fi.
• Build Quality & Durability: 8/10 - Sturdy construction, designed for professional use.
• Noise Level: 7/10 - Relatively quiet compared to some other 3D printing technologies.
• Maintenance Requirements: 6/10 - Requires regular cleaning of the resin vat, platform, and optical surfaces. Resin replacement is also a factor.
• Customer Support: 7/10 - EnvisionTEC (now part of Desktop Metal) offers support, but response times and the level of expertise can vary.
• Upgradeability: 4/10 - Limited upgrade options available for this specific model.
• Price to Performance Ratio: 7/10 - Expensive, but the superior print quality and accuracy justify the cost for specialized applications where those factors are paramount.

Average Score: 6.67/10

Conclusion:

The EnvisionTEC Micro Plus Hi-Res is a specialized tool designed for professionals who demand the highest level of detail and accuracy in their 3D printed parts. While it has a smaller build volume and requires more specialized knowledge than many other 3D printers, it excels in its niche. If your application requires micron-level precision, this printer is a strong contender. However, be prepared for the higher cost of entry, the learning curve associated with DLP printing, and the reliance on proprietary resins.
