Why Manufacturers Like Tesla Are Turning to Formlabs for Large-Format 3D Printing

In the automotive industry, tight timelines and high throughput are ever-present facts of life. Nowhere is this truer than Tesla's Gigafactory Nevada facility, where a small team of technicians is responsible for delivering thousands of fast-turn SLS parts each week. Here's how Tesla leverages the Formlabs Fuse X1 to churn out production parts on time, every time.

The Problem With Traditional SLS Printing

Selective Laser Sintering (SLS) has long been a go-to technology in the additive manufacturing arsenal, delivering durable high-resolution nylon parts fast and cheap. But SLS machines have historically come with size constraints, limiting their applicability for jigs, fixtures, and other tooling. While large parts can be split in CAD prior to printing, the design and assembly process adds lead time, and the joint introduces additional dimensional and strength concerns.

Large-format SLS systems exist and address the size concern, but often suffer from thermal inconsistencies within the build chamber, resulting in warpage and part packing challenges. Add to that a high equipment cost and steep learning curve, and it's no wonder most shops opt to stick with super glue.

How Formlabs' Fuse X1 Changes the Paradigm

The Formlabs Fuse X1 is designed specifically to address these challenges, bringing day-in, day-out reliability to a large-format platform. With a build volume of 330 x 330 x 565 mm, Fuse X1 delivers part sizes and/or quantities about 7.5 times larger than the Fuse 1+ 30W, without a commensurate increase in cycle time.

For Tesla, that additional build height means large parts print in one piece in 24-26 hours, without the need for pre-print CAD work or post-print assembly; and without losing the production throughput their team relies on.

Formlabs Fuse X1 Key Advantages

• Full build volume in a day -  With a full build taking 24 - 26 hours, no more printing at half height just to make a delivery window.
• Faster changeovers - Swapping build chambers takes about 15 minutes, compared to 45 minutes to an hour on traditional systems.
• Adaptive Thermal Control -  Thirteen independent thermal zones give consistent, precise temperature control across the build, which means less warping, more packing freedom, and higher-density builds without sacrificing dimensional accuracy.
• Faster onboarding - Where legacy large-format SLS machines can take weeks to train a new operator, Formlabs designed Fuse X1 to be production-ready for a new technician in about a day.
• Small footprint -  At roughly 12.5 sq ft, it's compact enough to add capacity without expanding your facility.

The Formlabs Ecosystem

The Formlabs Fuse X1 isn't an isolated success. Manufacturing teams that adopt Fuse X1 alongside other Formlabs systems (like the Form 4 and Form 4L SLA printers and the Fuse 1+ 30W) get a full-spectrum in-house manufacturing solution.

Fast SLA printing on Form 4 makes it possible to hand a high-resolution, show-quality prototype to an engineer within hours of the request. Formlabs' broad material library, from heat-resistant Rigid 10K Resin to ESD Resin for electronics to the impact-tolerant Tough Family of Resins, means the right material is always available for the application at hand.

For Tesla, reliability and support are just as important as speed. When uptime is critical, waiting days for a service visit grinds productivity to a halt. The ability to self-service equipment with fast shipping of replacement parts keeps production moving. Large-format SLS 3D printing can cut labor, shrink lead times, and reduce reliance on outsourced parts and injection molding.
