Formlabs Form 4L- Basic Package
$17,995.00 Incl. GST
Form 4L is a blazing-fast large-format masked SLA 3D printer that combines an industry-leading materials library with a reliable, accurate print engine. Turn your biggest ideas into reality faster than ever with easy workflows, leading reliability, and stunning part quality using the Form 4L ecosystem.
Form 4L’s speed is driven by Formlabs’ new Low Force Display™ Print Engine, a powerful combination of ultra-high power LEDs, collimating lenses, optical filters, and a robust liquid crystal display. Together they cure each layer of resin rapidly — regardless of part size or quantity. With tight tolerances, parts printed in every resin on Form 4L will match your design parameters, every time.

What's Included in the Form 4L Basic Package:
Low Force Display (LFD)™
At the core of the LFD print engine is the Backlight Unit. This ultra-high power light source uses 60 LEDs, integrated cooling, and collimating lenses, with industry-leading optical power intensity of 16 mw/cm2, to deliver blazing fast print speeds with excellent print quality and accuracy anywhere on the Build Platform.
The Backlight Unit emits a uniform area projection of light, which passes through the lens array, making the light more collimated, or parallel, and more uniform, eliminating dark or bright spots. The custom lens array is made of plano-convex lenses for highly collimated and uniform light even at high power.
From here, the light passes through the Light Processing Unit (LPU) 4, where it is formed into the shape of the printed layer using a series of polarizers, optical coatings, and a custom liquid crystal display. The 50 μm pixel size of the high-resolution LCD and pre-tuned anti-aliasing delivers sharp details, smooth surface finishes, and accurate tolerances. The custom LCD also features high light transmission, delivering maximum optical power to the resin and achieving blazing fast print speed.
Unlike existing LCD-based printers, the LPU 4 is long-lasting, engineered and manufactured to deliver 600,000 - 1,900,000 layers of consistent print performance before replacement, depending on the material and layer height printed. It is also robust to accidental damage, featuring a strong metal frame, scratch-resistant surface coating, and smart software (debris detection and force limits). When replacement is necessary, anyone can easily and quickly replace the LPU 4 at a low cost.
Once the light reaches the liquid resin inside the resin tank, the full liquid layer immediately cures into a solid layer. The Build Platform then rises out of the resin and a precision Z-axis peels away the layer from the bottom of the resin tank.
Form 4L Backlight unitForm 4L's custom lens array is made of plano-convex lenses for highly collimated and uniform light even at high power. The Backlight Unit cures the resin quickly and precisely, delivering blazing fast print speeds with excellent print quality and accuracy anywhere on the build platform. |
Release TextureA proprietary, microtextured optical film provides airflow between the resin tank and the Light Processing Unit. This film is built into the Light Processing Unit and sits at the top of it. This significantly reduces peel forces so you can print at blazing fast speeds without sacrificing surface finish, fine features, accuracy, or reliability. |
Form 4L Resin TanksThe Form 4L Resin Tank holds liquid resin inside the printer and provides a substrate for the liquid resin to cure against, using a dual-layer flexible film stack. It significantly reduces peel forces so you can print at blazing fast speeds without sacrificing surface finish, fine features, accuracy, or reliability. Every resin tank includes a reusable lid and stackable design, making it easy to stack tanks and store resin outside of the machine. With a separate tank for each individual resin color or type, switching materials is as easy as sliding in a new tank. |
Automatic Resin HandlingIntegrated system that dispenses resin quickly, accurately, and with minimal waste, while making it easy to switch materials. Print without having to worry about your printer running out of resin and switch materials in 1 minute. Form 4 is still one of the only SLA printers on the market to offer this feature. New resin cartridges still contain 1 L of resin, but 63% less plastic and 30% a smaller footprint for less plastic waste and shelf space. |
Intelligent Control Systems and Integrated Camera |
Multiple onboard control systems precisely measure and maintain the temperature, resin level, print forces, and print status inside Form 4L. In addition to the cartridge load cell sensor and conduction heating, Form 4L includes a printer leveling sensor, resin level sensor, integrated Z-axis force sensor, and a camera. Z-Axis Force Sensor: The Z-axis force sensor measures the forces being exerted on every layer during printing and automatically adjusts Z-axis motion to minimize those forces. This delivers optimal speed, quality, and reliability for any part geometry printed in any material. Integrated Camera: A camera inside the build chamber can take a photo or timelapse video of each completed print and upload it into Dashboard, Formlabs’ printer management software, where print status can be viewed from anywhere. This feature makes remote print monitoring and print history traceability easier than ever. For users wishing to opt out of this feature, the camera can easily be turned off, covered, or removed. Resin level sensor: measures the exact amount of resin in the Resin Tank and controls the automated resin dispensing system, ensuring consistent resin levels and print performance. Resin Temperature Sensors: Form 4 features conduction resin heaters and an infrared temperature sensor, enabling faster heating times and minimal time to start a print. The heater and infrared sensor precisely control resin temperature and unlock higher-viscosity materials. Mixer Debris Sensing: Checks for cured resin in the tank to quickly detect print failures. |
Built VolumeThe Formlabs Form 4L 3D printer has a build volume of 35.3 × 19.6 × 35.0 cm* and a capacity of 24.2 liters. |

Streamlined User Experience |
Form 4L builds off the intuitive user experience of Form 3L. With Wi-Fi, ethernet, and USB connectivity, plus power switches, it’s easier than ever to control your printer no matter your business needs. Additional updates mean Form 4 is more autonomous and intelligent, freeing up user time for higher-value tasks. Faster preprint times mean you can typically walk away from Form 4 less than a minute after starting. But, if a printer is ready, no printer interaction is necessary, simply send the print to the printer from your computer, and Form 4 will start printing automatically. |
Powerful 3D Print Preparation Software |
The full Formlabs ecosystem is designed to maximize efficiency and reduce the potential for print errors. Formlabs free print preparation software, PreForm, automatically analyzes the part and determines the optimal orientation and support placement. Formlabs software engineering team continuously improves software settings to ensure that print speed, materials settings, and automatic orientation and support are perfected. |
Resin Pumpin System (RPS)
Resin Pumping System (RPS) is available for Form 4L, providing 5 L of resin to the printer to enable less frequent cartridge changes and unlock discounted resin prices for time and cost savings.
