Stereolithography Materials
SLA/ Materials Available at Trendy
3D LASER PRINTING

Stereolithography (SLA/SLS/FDM) is a powerful 3D printing technology that produces extremely accurate and high-resolution parts that are capable of being used directly in end-use, low-volume production or for rapid prototype. TRENDY offers over 15 uniquely engineered SLA materials that can enable products to be brought to the market.

Printing Parts Case

Why choose Printing

♦ High Precision: SLA 3D printing offers excellent dimensional accuracy and high-resolution printing, making it suitable for applications requiring complex details and fine features.
♦ Smooth surface finish: SLA prints typically have a smooth and polished surface finish, reducing the need for extensive post-processing and providing a visually appealing end product.
♦ Broad material compatibility: SLA printers can use a variety of resin materials, including those with specific properties such as transparency, flexibility or high temperature resistance, allowing for a wide range of applications.
♦ Support structures: SLA printers can generate support structures that can be easily removed after printing, enabling the production of complex geometry and overhang structures without compromising the quality of the final print.
♦ Fast printing speed: SLA 3D printers can produce prints relatively quickly compared to other 3D printing technologies because they are able to cure the entire layer at once.
