The Formlabs Form Studio (Form Studio 1) represents Formlabs’ entry into the accessible prosumer resin 3D printing market. Operating on Low Force Display (LFD) stereolithography technology, it bridges the gap between low-cost desktop resin units and industrial-tier reliability by eliminating messy manual workflows and addressing home safety concerns.
The Form Studio relies on a masked SLA system powered by the Light Processing Unit Studio 1 (LPU S1) and a custom backlight system:
| Metric | Specification |
| Build Volume | 200 x 125 x 235 mm |
| Pixel Resolution | 35 µm (outperforming larger industrial SLA units in raw XY pixel density) |
| Average Print Speed | ~40 mm/hr across standard materials |
| Max Print Speed | Up to 130 mm/hr (with Alpha Fast Resin) |
| Dimensional Accuracy | ±0.08 mm lower tolerance limit for small features (1–30 mm) |
| Sensor Suite | 5 integrated control systems monitoring resin levels, temperature, print force, and status |
Formlabs introduced the budget-conscious Alpha Resin family ($29/L). Formulated for low odor and certified skin-safe after curing (compliant with ISO 10993 standards for skin contact), the line includes:
When paired with the optional VOC Extractor add-on unit, the Form Studio becomes the industry’s first desktop resin printer system to receive UL GREENGUARD Gold Certification for low chemical emissions.

Part detachment and washing/curing are handled through dedicated accessories:
| Category | Form Studio (LFD SLA) | Typical FDM Printers |
| Surface Finish | Smooth, layer-free aesthetic right off the platform (35 µm resolution). | Visible layer lines and stringing; requires sanding/filler. |
| Batch Production Speed | Exposure time is constant per layer; full build volume speed remains unchanged regardless of part count. | Print times scale linearly with each added object on the build plate. |
| Multi-Material / Color | Single-material prints; requires painting or tinting for color variety. | Native multi-filament, multi-color capabilities via AMS/MMU attachments. |
| Indoor Safety | UL GREENGUARD Gold certified low emissions when using Alpha Resins and VOC Extractor. | Variable emissions depending on filament (e.g., ABS/ASA require external enclosures/ventilation). |
| Feature | Form Studio | Form 4 / 4B |
| Target Audience | Prosumers, hobbyists, educators, smaller design studios. | Engineering labs, medical facilities, dental clinics, industrial production. |
| Build Volume | 200 x 125 x 235 mm | 200 x 125 x 210 mm (Slightly smaller height, larger chassis). |
| XY Pixel Resolution | 35 µm (Finer detail for micro-features). | 50 µm. |
| Light Output | 6 mW/cm² (28 LEDs). | 16 mW/cm² (60 LEDs). |
| Hardware Complexity | Simplified system without internal mechanical mixers or thermal tank heating. | Integrated resin mixer, advanced thermal control loop, dual force sensors. |
| Material Library | Alpha Resin Line + Standard Engineering/Castable catalog & Open Mode. | Full catalog (Flame Retardant, Rigid 10K, ESD, Biocompatible Medical/Dental). |
| Price Tier | Entry-level prosumer pricing (Starting at $699 Base / $948 Complete). | Premium industrial pricing tier ($3,999+). |
The Formlabs Form Studio is an accessible, desktop Low Force Display (LFD) resin 3D printer designed for prosumers, educators, and design studios. It combines industrial print quality and high pixel detail (35 µm) with low-cost, low-hazard workflows.
Yes. When paired with Formlabs Alpha Resins and the optional VOC Extractor unit, the Form Studio is UL GREENGUARD Gold certified for indoor air safety, drastically reducing chemical odors and VOC emissions during printing.
The Form Studio offers a build volume of 200 x 125 x 235 mm and a pixel resolution of 35 µm, providing sharper XY detail for small features than many industrial-class SLA machines.
Standard print speed averages around 40 mm/hr. When using specialized materials like Alpha Fast Resin, print speeds can reach up to 130 mm/hr, completing full-height builds in under two hours.
Alpha Resins are Formlabs’ budget-friendly resin line ($29/L). They feature low-odor formulations and are certified skin-safe once cured (ISO 10993 compliant). The line includes Standard (Gray, White, Black), Fast, Model, and Clear varieties.
Yes, the Form Studio supports non-Formlabs materials through Open Mode. However, third-party materials require manual exposure profile tuning in PreForm and invalidate the printer’s UL GREENGUARD Gold air safety certification.
Parts printed on the quick-release Build Platform Flex easily detach by bending the platform. They are then cleaned and cured using the compact, all-in-one Form Studio Wash+Cure unit, which utilizes UV light-only curing tailored for Alpha Resins.
The Form Studio offers a finer pixel resolution (35 µm vs. 50 µm) and a lower entry price for prosumers. The Form 4 delivers higher optical power output (16 mW/cm² vs. 6 mW/cm²), integrated resin mixers/heaters, and access to an extensive engineering, medical, and biocompatible material library.
