Stereolithography also requires build supports which are removed manually by hand, meaning areas that require support be accessible. Stereolithography support material is the same material as the final part. During printing, the resin within the chamber can become trapped within the part or pool in ...
All FDM prints, even those made with specialty high-temperature filament, will melt at a high enough temperature. Most FDM materials are amorphous thermoplastics, meaning they gradually deform as viscosity decreases past their glass transition temperature (often written Tg). Some FDM materials like ny...
Ensure that the 3D model is watertight, meaning it has completely closed surfaces with no holes or self-intersecting faces. Use 3D modeling software to identify and fix any non-manifold geometry issues. Double-check the model for closure and potential issues before exporting it for printing....
Formlabs introduced inverted stereolithography 3D printing in 2011 with the Form 1. With the inverted SLA process, a light source (a laser in Form 1) cures the cross-section of the part through a transparent-bottomed resin tank, meaning only a thin layer of resin needs to be dispensed and ...
Once printing is complete, the part remains in a partially cured state. Additional post-processing under UV light is often required to enhance its mechanical and thermal properties. Unlike thermoplastics used in fused deposition modeling (FDM), SLA materials are thermoset polymers, meaning the curing...
Compare FDM and SLA 3D printing methods to determine which one to use based on their strengths, weaknesses, and features.

One of the primary considerations when deciding between FDM and SLA 3D printing is material cost. FDM materials, such as PLA or PETG, are significantly more affordable than SLA resins, with filament prices often ranging between $20 and $50 per kilogram. By contrast, SLA resin costs can start...
