Fast / Accurate / Reliable

Crazy Fast

Print time is similar whether you run a single part or fill the build area, helping you keep iteration cycles moving without waiting.

  • Maximum print speed: up to 100 mm/hour
  • Typical print speed: average 40 mm/hour across materials (16–50 mm/hour range depending on resin)

Extreme Accuracy

Designed for crisp features and consistent fit across the platform, with 50 µm pixels and tuned anti-aliasing to deliver clean edges & fine detail.

  • XY resolution: 50 µm with pre-tuned anti-aliasing for subpixel resolution
  • Typical XY tolerances: ±0.15% for 1–30 mm features (lower limit ±0.02 mm)

Reliable & Repeatable

Engineered around validated settings, sensor-driven control, and factory calibration to reduce failed prints and rework.

  • 98.7% print success rate measured in independent third-party testing
  • Remote monitoring, print history, and alerts via Dashboard

Premium workflow: fast prints with production-ready surface finish.


Materials + Workflow

Form 4 is built around a straightforward resin workflow, with print preparation in PreForm and printer management in Dashboard. The process is designed to stay consistent from model import through post-processing.

From model to finished part

  • Prepare: Import your model and use auto-orientation, support generation, and printability checks in PreForm.
  • Print: Load a resin cartridge and start the job with validated print settings and automatic resin dispensing.
  • Post-process: Remove parts, then wash and cure to achieve target material properties.
  • Finish: Light-touch supports help speed up support removal; apply optional sanding/coating/painting as needed.

Material flexibility

Choose from 23 Formlabs materials, or run compatible third-party resins using Open Material Mode; Rigid, Tough, General Purpose, Flame Retardant, Silicone, Elastic, Biocompatible, Ceramic, Castable etc.

Recommended add-ons

  • Form Wash (automated cleaning)
  • Form Cure (precision post-curing)
  • Additional Resin Tank(s) for fast material changeovers
  • Extra resin cartridges for uninterrupted production runs

Who It’s For

Rapid Prototyping

  • Turn around concept-to-check parts quickly
  • Improve iteration cadence without waiting overnight

Ideal for product teams that need multiple design loops per week and want consistent surface finish for reviews, fit checks, and presentation models.

Pre-Production Validation

  • Test geometry, function, and assembly fit before committing to tooling
  • Use engineering resins to match real-world demands

Useful when you need confidence in a design decision before you spend time and money on machining or mould tooling.

Manufacturing Aids

  • Create jigs, fixtures, and assembly tools with consistent repeatability
  • Print parts that are easy to finish and put into use

A strong fit for production environments that benefit from faster custom tooling without sacrificing fit and accuracy.

Consumer Products

  • Produce highly detailed cosmetic parts for evaluation
  • Keep surfaces smooth to reduce finishing effort

Great for design studios that want clean presentation quality straight off the printer, with minimal sanding and touch-up.

Engineering + R&D

  • Print complex geometry with tight feature control
  • Move from CAD to test part using PreForm and validated profiles

For engineers who need repeatable results, dimensional consistency, and a reliable workflow they can hand to multiple users.

Education + Research

  • Simple guided workflow designed to be learnable quickly
  • Remote monitoring and alerts to support shared lab use

A strong fit for labs and classrooms that want professional resin printing outcomes with an approachable day-to-day process.

FAQ

1) What printing technology does Form 4 use?

Form 4 uses MSLA (Masked Stereolithography) with a Low Force Display™ (LFD) print engine designed to deliver consistent light distribution and controlled peel forces.

2) Can I use third-party resins?

Yes. In addition to Formlabs materials, Form 4 supports compatible third-party resins through Open Material Mode.

3) Which software do I need?

Use PreForm to prepare prints (supports, orientation, and slicing) and Dashboard for printer management, monitoring, history, and alerts.

4) What file types can I send to PreForm?

PreForm supports STL, OBJ, and 3MF inputs, and outputs a FORM file for printing.

5) Does it require a special environment?

Form 4 is specified to operate in an 18–28 °C environment. For best results, keep the printer in a stable indoor space and follow resin handling guidance for your chosen material.

6) How do I receive notifications if a print finishes or needs attention?

The printer provides on-screen alerts, and Dashboard can send SMS/email alerts for supported events.

7) Does Form 4 support biocompatible materials?

Biocompatible material support is listed for the Form 4B variant rather than Form 4.

8) What connectivity options are available?

Form 4 supports Wi-Fi (2.4/5 GHz), Ethernet (gigabit), and USB-C connectivity.

9) Do I need post-processing equipment?

Washing and curing are part of the standard resin workflow. You can do this manually, but Form Wash and Form Cure are designed to automate and standardise those steps.

10) What’s the easiest way to choose the right configuration?

Tell us what you’re printing (application, material needs, throughput goals) and whether you want a printer-only setup or a complete workflow (wash/cure, extra tanks, and consumables). We’ll recommend the most practical package.
