Accelerate Prototyping with the Speed and Reliability of the Formlabs Form 4

We’ve all been there: you send a CAD file to an outsourced bureau and then… you wait. Days turn into a week, and when the part finally arrives, a single tolerance issue sends you back to square one. Or maybe you’re printing in-house, but you spend half your day babysitting a machine that fails 20% of the time, forcing you to restart prints and miss deadlines. It’s a workflow bottleneck that kills momentum and keeps you late at the office.

There is a better way to prototype. The Formlabs Form 4 is designed to bring industrial-grade speed and reliability directly to your workbench, cutting out the middleman and the waiting game. By combining a new Low Force Display™ (LFD) print engine with a massive library of engineering materials, this printer doesn't just make parts; it gives you your time back. It’s fast enough to iterate twice in a single day and reliable enough to run overnight without a second thought.

Why the Form 4 belongs in your engineering lab

1. Blazing fast turnaround times. With print speeds up to five times faster than previous generations, the Form 4 can finish most engineering parts in under two hours. You can design in the morning, print before lunch, and test a functional prototype by the afternoon.

2. Stop babysitting your printer. Thanks to intelligent sensors and the new LFD print engine, the Form 4 delivers a near-perfect 99% print success rate. You can hit "Print" and walk away with total confidence, knowing your part will be there when you return, accurate and ready to use.

3. One machine, endless material possibilities. Swap between 23+ specialized resins in seconds to match your exact project needs. Whether you need the impact resistance of Tough 2000, the stiffness of Rigid 10K, or soft, rubber-like Flexible 80A, this single platform handles it all without complex recalibration.

4. Injection-molded quality right off the build plate. Achieve surface finishes and dimensional accuracy that rival final production parts. The Form 4 produces crisp, clean geometries with tight tolerances, making it perfect for client presentations or validating fit and snap mechanisms before tooling.

5. Slash your development costs. Bringing high-performance SLA printing in-house drastically reduces the cost per part compared to outsourcing. You eliminate rush fees and shipping costs while gaining the agility to print as many iterations as you need to get the design perfect.

6. Zero-hassle workflow. You don’t need a specialized technician to run this machine; the intuitive workflow allows anyone on the team to learn the basics in about 15 minutes. From automatic resin handling to quick-release build platforms, every touchpoint is designed to keep you focused on engineering, not maintenance.

Reliability is the currency of engineering, and the Form 4 pays dividends by removing the variables that usually slow you down. Instead of crossing your fingers and hoping for a good print or waiting on a courier, you gain complete control over your production timeline. This is about more than just a printer; it’s about tightening your feedback loop and shipping better products faster.
