Formlabs Form 4L
The future of professional grade 3D printing.
Role
Lead Industrial Designer
Years
2022 - 2024
The Form 4L is the culmination of my six years at Formlabs. It combines the technical advances of the Form 4 with massively improved user experience to create the ultimate large format resin printer.
Exterior Design
Defining the future of professional-grade resin 3D printers.
I began to explore how we could combine aspects of industrial and prosumer machines with the approachable, desk-friendly hardware our customers expect. What could be borrow from previous Formlabs product? What form and material choices can we make to elevate the Form 4 above other resin printers on the market? How can the exterior reflect the massive internal improvements?
A machine that celebrates the user's part.
The final design concept for the Form 4 communicates reliability, drawing inspiration from traditional tool design and prosumer products with a minimalist aluminum base and clear user touch points. The design, while striking, also recedes from view when a print is present, acting as a stage to celebrate the user's part. It pushes Formlabs' hardware design language forward, emphasizing robustness and reliability.
Front & Rear Shells.
My contributions to the exterior design centered on the front and rear shells of the machine. The rear shell is curved, reducing the apparent depth of the machine and improving its stance on the user's desk. It incorporates all of the I/O and power ports of the machine, as well as a filtered air intake for the the cooling system.

The front shell is a single piece of die-case aluminum, half of which angles inward to create a more visible and accessible surface the touchscreen display.
The bisected form encapsulates the theme of the entire machine - bare, solid material on one side, and intuitive interaction on the other.
Cross-team collaboration.
The Industrial Design team collaborated with the engineering and manufacturing teams on every cosmetic and UX-critical part. This included the creation of production CAD, technical drawings, surface quality standards, and inspection documents.
Color, Material & Finish.
We developed a new palette of minimal greys that provide sufficient contrast between parts while remaining subdued and sophisticated. This included a chemical-resistant silver powder coat inspired by bead blasted & clear anodized aluminum that we use on much of the exterior shell. We also improved our orange cover material to maximize internal visibility and formalized the use of Formlabs Touchpoint Blue on key areas of user interaction.

Build Platform
Latch it, print it, flip it, flex it.
The Form 4 Build Platform prints 30% larger parts than Form 3, and includes a new integrated leveling system to ensure part quality. These factors, combined with the frequency of build platform interactions, led me to completely redesign the handle and flexible print surface.
Larger parts without compromise.
I worked closely with the engineering team on the leveling mechanism, squeezing every millimeter of space so that the handle could fit within the user's hand. After dozens of iterations, I arrived at a handle design that maximized comfort, manufacturability, and ease of use. I also designed Build Platform Flex, and extension of my work on Build Platform 2L, bringing our best part removal workflows to the Form 4.

Resin Tank
A resin tank you can rely on.
The Form 4 Resin Tank was one of my main contributions to the project. With intuitive tank insertion, RFID identification, reduced plastic waste, and nearly unlimited lifetime, this is the best tank ever shipped on a Formlabs product.
Mechanical Prototyping.
The tank has a totally new design, so it needed a totally new method of insertion. We explored various methods, from electro-mechanical arms to electromagnets, but ultimately settled on a set simple, robust latches that borrow their UX from Tupperware lids.
Simple & Reliable.
The new latching mechanism and RFID sensors make tank insertion and identification significantly more reliable than any previous Formlabs printer. The Form 2 mixer also returns, with a similarly updated latch. Additionally, my tank redesign no longer requires a case for storage, eliminating a major source of plastic waste from the ecosystem.

"Form 4 is our go-to choice for projects needing tight tolerances and engineering-grade materials. It produces high-performance parts with amazingly fast print times and makes it possible for our model makers to produce multiple iterations in a 24-hour period."
Mark Honschke
Additive Prototyping Lead
“The dramatic increase in print speed for Form 4 has significantly accelerated our fabrication cycle – to the point where I can iterate through many different designs every day and go from design to usable, functional part within the hour."
Matt Mullin
Laser Engineer
"Form 4's speed and materials versatility enable us to create multiple prototypes and manufacturing aids every day. The printer has already changed the way we design and produce parts, helping us drive efficiency in our product development"
Bruno Alves
Development Engineer AM/IM
"With Form 4, it throws time out the window. A huge reason we use SLA over FDM is material options. We run about 12-15 different Formlabs materials that we use for a variety of reasons."
Jesse Emanuel
Prototype Engineer
"I really appreciate the reliability paired with the speed. It's not one or the other, like many other tools. Now I can commit to internal deadlines and feel confident that I can deliver every time."
Robert Mackowiak
Rapid Prototyping Engineer
“On one lighting project, we did three iterations in a single day — designed and printed three different parts before we had a meeting in the afternoon. [...] We haven’t had a single failure on the Form 4.”
