    Grey Resin

    Grey resin is perfect for general purpose prototyping and design, excellent for capturing small details. Supports print resolutions: 100, 50, and 25 microns.

    Formlabs Materials

    Outstanding performance. Beautiful results.

    Formulated to deliver the highest-quality output, Formlabs resin captures astonishing detail without sacrificing durability and toughness.


    For demanding applications, our carefully-engineered resins capture the finest features in your model.

    Strength & Precision

    Formlabs resins create accurate and robust parts, ideal for rapid prototyping and product development.

    Surface finishes

    Perfectly smooth right out of the printer, parts printed on the Form 2 SLA 3D Printer have the polish and finish of a final product

    Form 2 3D Printer

    A good print starts with a well-designed model that is optimized for 3D printing. We've created this design guide to outline some of the minimum features you can expect from Formlabs printers.

    Please note: The guidelines below have been developed using Formlabs Clear resin printing at 100 microns. You may experience slight variations with other Formlabs resins and other layer heights.

    Minimum Supported Wall Thickness

    Recommended: 0.4 mm

    A supported wall is one that is connected to other walls on two or more sides. A supported wall smaller than 0.4 mm may warp during the peel process.

    Minimum Unsupported Wall Thickness

    Recommended: 0.6 mm

    An unsupported wall is one that is connected to other walls on fewer than two sides. An unsupported wall that is smaller than 0.6 mm may warp or detach from the model during printing.

    Maximum Unsupported Overhang Length

    Recommended: 1.0 mm

    An overhang refers to a part of the model that sticks out horizontally parallel to the build platform. Printing such features without supports is discouraged, as the layers cannot maintain their structure. Horizontal overhangs will be slightly deformed beyond 1 mm and become increasingly deformed as the length of the overhang increases. You can turn on “internal supports” in PreForm to ensure your overhangs are supported.

    Minimum Unsupported Overhang Angle

    Recommended: 19° from level

    The overhang angle refers to the angle from horizontal that the overhang sticks out. Printing at an angle less than 19° could cause the overhang to break off the model during the peel process. Rotate your part so flat surfaces can be held up by supports if they are not already self-supporting.

    Maximum Horizontal Support Span/Bridge

    Recommended: 21 mm

    A span is the distance between two intermediate supports of a structure. While printing horizontal spans is discouraged, certain geometries print well. For a 5 mm wide and 3 mm thick beam, spans longer than 21 mm are likely to fail. Wider beams must be kept shorter to avoid breaking during the peeling process.

    Minimum Vertical-Wire Diameter

    Recommended: 0.3 mm (7 mm tall) to 1.5 mm (30 mm tall)

    A wire is a feature whose length is greater than two times its width. The ratio is key to printing wires; at 0.3 mm thickness you can print up to 7 mm tall before you start to see waving. 1.5 mm wires can get up to 30 mm tall without defects.

    Minimum Embossed Detail

    Recommended: 0.1 mm

    Embossed details are shallow raised features on your model, such as text. Details smaller than 0.1 mm in thickness and in height may not be visible on your print.

    Minimum Engraved Detail

    Recommended: 0.4 mm

    Engraved details are imprinted or recessed features on your model. Details recessed less than 0.4 mm in thickness and in height may not be visible because they will be fused with the rest of the model during the print process.

    Minimum Clearance

    Recommended: 0.5 mm

    Clearance is the amount of distance needed between two moving parts of a model (e.g., the distance between gears or joints). A clearance of less than 0.5 mm may cause parts to fuse.

    Minimum Hole Diameter

    Recommended: 0.5 mm

    Holes with a diameter less than 0.5 mm in the x, y, and z axes may close off during printing.

    Minimum Drain Hole Diameter

    Recommended: 3.5 mm diameter

    Drain holes are recommended for resin to escape in models that are a fully enclosed cavity (like a hollow sphere or hollow cylinder printed directly on the build platform). Without drain holes of at least 3.5 mm in diameter, the part may trap resin and lead to an explosion of the print.
