Form 4L vs. Form 3L

Industrial Parts at Blazing Speed

Learn how you can power your productivity, and improve part quality, workflows, and time efficiency, by upgrading from Form 3L to Form 4L.

Improvement

form 4 vs. form 3

2-4x faster print speeds across all materials for most large prints in under six hours for faster iterations and higher throughput.

“Form 4L allows us to print large parts fast. For example, we use the Form 4L to print setup parts for our weld cell in just hours instead of overnight.”

Matthias Schulz, Seat Division Prototyping Manager, Brose

13% larger build volume and 6% larger maximum part length for larger parts and increased throughput.

Six new resins provide higher performance, richer color, and crisper features – all at a fraction of the price of the Form 3L equivalents.

Surface finish that rivals injection molding for improved aesthetics and presentation-ready parts.

Improved Reliability and Consistency

Sharpest details to produce parts with the finest and most intricate features, uniform finishes, and no seamline for less time spent finishing parts.

Improved tank lifetime and management to minimize upkeep costs and waste.

Cartridge redesign for hassle-free, efficient, and fast automatic resin dispensing.

Access images and timelapses online to remotely monitor your prints.

"We’ve pushed Form 4BL to its limits, and it hasn’t failed a single print. Its reliability under pressure has been outstanding."- Brian Albers, 3D Printing Engineer, St. Louis Children’s Hospital.

“As a dental lab, reliability is essential for us to deliver our products on time. With Formlabs’ ecosystem, our 3D print success rate is now close to 100%. Compared to other 3D printers we’ve used in the past, Formlabs shows much higher performance and reliability.” - Stephan Kreimer, MDT, Kreimer Dentallabor.

Clear Resin V5 compare to Clear Resin v4

Clear Resin V5 (left, for Form 4L) vs. Clear Resin V4 (right, for Form 3L).

Grey Resin V5 (left, for Form 4L) is darker and richer in color than Grey Resin V4 (right, for Form 3L). It is also tougher, with a 30% higher impact strength, and prints 4x faster.
