When choosing between Fused Deposition Modeling (FDM) and Stereolithography (SLA), the right answer depends on your application’s requirements for accuracy, material properties, and cost.
FDM builds parts layer-by-layer using thermoplastic filaments. It is the most widely used 3D printing technology: cost-effective, fast, and compatible with engineering-grade materials including ABS, PLA, PETG, Nylon, and TPU. At Aminish Technologies our FDM machines achieve layer resolutions down to 0.1 mm, making them ideal for functional prototypes, jigs, fixtures, and end-use production parts.
SLA uses a UV laser to cure photopolymer resin layer by layer, delivering exceptional surface finish and dimensional accuracy. Surface roughness values of Ra ≤ 0.8 µm are routinely achievable, making SLA the preferred choice for visual prototypes, dental models, and intricate engineering components where cosmetic quality matters.
Choose FDM when you need durable, functional parts at lower cost. Choose SLA when surface finish and detail resolution are critical. Aminish Technologies offers both — contact our team for a recommendation tailored to your project.
