Diving Deep into the Formlabs Form 3+: A Detailed Look at Resin 3D Printing Excellence

The Formlabs Form 3+ represents a significant step forward in desktop stereolithography (SLA) 3D printing. Designed for engineers, designers, and manufacturers seeking high-precision, reliable printing with a wide range of materials, the Form 3+ aims to deliver professional-grade results without the complexity often associated with industrial-scale 3D printers. This article provides a comprehensive look at the Form 3+, examining its specifications, offering usage tips, and evaluating its strengths and weaknesses.

What is the Form 3+?

The Form 3+ is a resin-based 3D printer that utilizes Low Force Stereolithography (LFS) technology. This means it uses a flexible resin tank to minimize peel forces during printing, allowing for finer details and less support structure usage. It builds parts by selectively curing liquid resin with a laser, layer by layer, until a complete 3D object is formed.

Detailed Specifications:

Here’s a breakdown of the key specifications for the Formlabs Form 3+:

• Printing Technology: Low Force Stereolithography (LFS)
• Build Volume: 14.5 x 14.5 x 18.5 cm (5.7 x 5.7 x 7.3 in)
• Laser Spot Size: 85 μm
• Layer Resolution (Z Axis): 25 - 300 μm (0.001 - 0.012 in)
• Materials: Wide range of Formlabs resins, including:
  • Standard Resins (Clear, Grey, White, Black, Navy)
  • Engineering Resins (Tough, Durable, High Temp, Rigid)
  • Dental Resins (Surgical Guide, Dental LT Clear, Model)
  • Medical Resins (Biocompatible)
• Connectivity: Wi-Fi, Ethernet, USB
• Software: PreForm (for print preparation and slicing)
• Printer Dimensions: 40.5 x 37.5 x 53 cm (15.9 x 14.8 x 20.9 in)
• Weight: 17.5 kg (38.5 lbs)

Key Features and Benefits:

• High Precision and Detail: LFS technology enables the printing of parts with intricate details and smooth surface finishes.
• Wide Material Compatibility: The extensive range of Formlabs resins allows users to select the optimal material for their specific application, from prototyping to functional parts.
• Reliable Printing: The Form 3+ is designed for consistent and reliable printing, minimizing print failures and maximizing uptime.
• Automated Workflow: PreForm software and simplified post-processing tools streamline the printing process, making it more accessible for users of all skill levels.
• Remote Printing and Monitoring: Print progress can be monitored remotely via the Formlabs Dashboard, allowing for greater flexibility and control.

Usage Tips for Optimal Results:

To get the most out of your Form 3+, consider these tips:

• Resin Selection: Carefully choose the resin that best suits your application. Consider factors such as strength, flexibility, temperature resistance, and biocompatibility. Refer to Formlabs’ material datasheets for detailed specifications.
• Orientation and Support Generation: Use PreForm’s auto-orientation and auto-support features as a starting point, but don’t be afraid to adjust them manually. Orient parts to minimize support structures and optimize surface finish. Pay close attention to areas that may trap resin.
• Layer Height: Choose the appropriate layer height for your print. Lower layer heights will result in finer details but longer print times.
• Resin Tank Care: Regularly inspect and clean the resin tank to remove any debris or cured resin. Replace the tank according to Formlabs’ recommendations.
• Resin Management: Ensure that the resin cartridge is properly seated and that the resin is dispensed correctly. Keep resin cartridges stored in a cool, dark place when not in use.
• Post-Processing: Proper post-processing is crucial for achieving the desired part properties and finish. This includes washing the part in isopropyl alcohol (IPA) to remove uncured resin, followed by curing in a Form Cure or similar UV curing chamber. Follow Formlabs’ recommendations for wash and cure times for each resin.
• Software Updates: Keep PreForm and the printer firmware up to date to benefit from the latest features, bug fixes, and material profiles.
• Calibration: Periodically calibrate the printer according to Formlabs’ instructions to ensure optimal print accuracy.

Strengths:

• Excellent print quality and surface finish.
• Broad range of compatible materials.
• User-friendly software and streamlined workflow.
• Reliable performance.
• Remote monitoring capabilities.

Weaknesses:

• Relatively small build volume compared to some other 3D printers.
• Resin cartridges can be expensive.
• Post-processing is required, which adds time and expense.
• Resin fumes can be an issue in poorly ventilated areas (although the Form 3+ has improved ventilation compared to earlier models).

Overall Score and Breakdown:

Here’s a rating breakdown of the Formlabs Form 3+ based on key performance categories:

• Print Quality: 9/10
• Build Volume: 7/10
• Printing Speed: 7/10
• Material Compatibility: 9/10
• Bed Adhesion & Leveling: 9/10
• Reliability: 8/10
• Ease of Use: 8/10
• Firmware and Software: 9/10
• Connectivity Options: 8/10
• Build Quality & Durability: 9/10
• Noise Level: 7/10
• Maintenance Requirements: 7/10
• Customer Support: 8/10
• Upgradeability: 6/10 (limited upgrade options)
• Price to Performance Ratio: 7/10

Average Score: 7.8/10

Conclusion:

The Formlabs Form 3+ is a powerful and versatile resin 3D printer that delivers exceptional print quality and a wide range of material options. While it may not be the cheapest option on the market, its ease of use, reliability, and professional-grade results make it a valuable tool for designers, engineers, and manufacturers looking to create high-precision parts. If you require a larger build volume or prioritize speed above all else, other printers might be more suitable. However, for those seeking the best possible print quality and material compatibility in a desktop SLA printer, the Form 3+ is a strong contender.
