Frequently Asked Questions
What is 3D printing?
3D printing, also known as additive manufacturing, is a method for fabricating a physical object from a digital model. Whereas traditional “subtractive manufacturing” cuts material away from a solid piece of material (i.e. wood carving or metal machining) to create an object, 3D printing adds layer upon layer of material to gradually build an object. For a simple visualization, imagine placing successive circular sheets of paper on top of one another until the stack becomes a three dimensional cylinder.
Why is the Form 1+ better than other 3D printers?
The Form 1+ is a high-resolution desktop machine that matches the print quality of large, industrial printers at a far lower cost. The Form 1+ uses stereolithography (SLA) technology to achieve a professional print quality that plastic extrusion printers just can’t match. Stereolithography is the gold standard for accuracy and resolution in 3D printing. Our custom PreForm software and single button interface make the entire print experience simple, intuitive, and enjoyable. Learn more about the Form 1+ printer.
What is the difference between stereolithography/SL and plastic extrusion/FDM?
Plastic extrusion, or fused deposition modeling (FDM), is the most common desktop 3d printer technology; FDM printers melt plastic and use an extruder to print each layer with molten plastic. The vast majority of desktop plastic extrusion machines lack the finish and resolution for professional-grade output. SL can outperform the print quality of even high-end FDM machines. In our photopolymer-based process, a high precision system directs a laser across a tray of liquid resin and causes a thin layer to solidify. Until now, a professional SL printer has been far out of reach for the individual designer.
The Form 1+
What is the resolution of the printer?
Different 3D printer manufacturers use different metrics to define “resolution”, but layer thickness is one commonly cited standard. The Form 1+ can create layers as thin as 25 microns, which is much finer than other desktop machines. Minimum feature size, on the other hand, refers to the thinnest wall or finest point, which can be as small as 300 microns on the Form 1+. The Form 1+’s laser beam can move in steps of fewer than 10 microns, creating extremely precise movements and an impressively smooth surface finish that FDM machines can’t match.
What are the dimensions of the Form 1+’s build volume?
The build envelope dimensions are 125 x 125 x 165 mm (4.9 x 4.9 x 6.5 in). For larger models, you may be able to print multiple segments.
How fast does the Form 1+ print?
The build speed is comparable to FDM machines when comparing layer thickness and density. As a general rule, the build speed is 1-3 cm/hour along the Z axis when printing at 100 microns. Our rook, as an example, takes around 2 hours to print at 100 micron layer-height. Recently, we added a 200 micron layer-height setting that works with our Clear resin to reduce print times. The same rook at 200 microns takes 45 minutes to print. To calculate the print speed of any specific part, please download our PreForm application, load the model, and calculate the print time.
What do I need to use the Form 1+?
The Form 1+ arrives fully assembled, calibrated, and ready to use! Each Form 1+ order also includes 1 liter of resin and a kit to help finish your prints. All you need is a laptop with our PreForm software installed, a 3D model to print, and isopropyl alcohol (IPA), to rinse your printed model. Refer to our Help Pages for detailed instructions.
What are the technical specifications of the Form 1+?
Read our full list of technical specifications.
What consumables does the Form 1+ have?
The Form 1+ uses a liquid photopolymer resin, which is described in detail in the Materials section. Resin tanks wear with use and need to be replaced periodically, typically after being used with 2L of resin.
How much maintenance is required for the Form 1+?
The Form 1+ was designed for ease of use and low maintenance. We streamlined the number of moving parts to reduce wear on the machine while making operation of the printer simple and intuitive. We have also compiled instructions that describe how to care for your Form 1+.

What resin does the Form 1+ print with?
Formlabs offers Black, Grey, Clear and White; standard resins for general prototyping. These carefully-engineered resins produce accurate and robust physical models. Formlabs also offers functional resins with varying mechanical properties such as Castable and Flexible. Based on our users’ needs, Formlabs is actively developing new materials with varying aesthetic and mechanical properties. To purchase resin or obtain an MSDS, visit our materials page.
How many parts can I print with 1 bottle of resin?
Depending on your print size, 1 liter of resin can print various quantities of models. For example, our standard rook measures 53 mm tall and uses about 11 cubic centimeters (or 11 mL) of resin. One liter of resin could produce about 90 rooks!
Our PreForm software will tell you how much resin the model you are printing will use before your start each print.
What are the material properties of the resin and how does it compare with other materials?
Formlabs’ photopolymer resins are ideal for product development and rapid prototyping. In combination with stereolithographic technology, these materials exhibit smooth surface finishes and excellently capture fine details on your prints. Our standard resins are great general purpose rapid prototyping resins. Our Castable Resin is optimized to burn out cleanly for investment casting applications, while our Flexible Resin has great compression characteristics for a host of engineering applications. For detailed material properties, please download our material datasheets from our materials page.
What is the shelf-life of the resin?
Our bottled resin has a shelf life of at least one year. You can leave unused resin in the Form 1+ resin tank for as many as two months, which means you won’t have to waste any material.
How can I store the resin?
You can reuse resin that is in your tank after a print, but it should not be returned to the bottle to avoid potential contamination. The Form 1+’s orange cover will protect your unused resin from ambient light. Outside of the printer or bottle, resin can be stored in the orange resin tank with the lid on.
Where can I find the material MSDS?
For more information about safely handling our resin, see our materials page.
Can the resin be burnt-out, for lost-wax casting?
Our Castable Resin was developed specifically for investment casting. The material burns out cleanly with very low shrinkage. Parts printed on the Form 1+ must be post-cured before casting. Please follow our recommended burnout schedule when working with this material for optimal results.
Can I use third party resins with my Form 1+?
No. The resin properties we’ve engineered in house are closely linked with the Form 1+ design. Third party resins are unlikely to perform as well and may actually damage the printer or void the warranty.
