Axtra3D introduced Spectroplast TrueSilX50 silicone formulations for 3D printing

Charlotte, NC – Axtra3D has introduced Spectroplast TrueSilX50, a true silicone formulation designed exclusively for the Axtra3D Lumia X1 printer. The availability of this solution and material expands the Axtra Solutions™ portfolio, for industrial and healthcare applications.

Building upon Axtra3D’s no-tradeoff Hi-Speed SLA technology, TrueSilX50 enables the high-precision, high-speed printing of fully elastomeric silicone parts without compromising material integrity or performance. Its properties mark this as a significant breakthrough over extruded silicone, becoming the first pure silicone material to be processed using photopolymerization AM, achieving superior part quality, accuracy, and mechanical properties.

TrueSilX50, the first in a series of silicone materials, brings the durability and flexibility expected of molded silicone into a scalable, production-ready 3D printing process. With a 48A Shore Durometer, 330% Elongation at Break, and 22N/m tear strength, it meets the mechanical demands of medical, industrial, and wearable applications. Biocompatibility testing is currently in progress, and Axtra3D anticipates that this material will pass key biocompatibility tests, including Cytotoxicity, Skin Irritation, and Skin Sensitization, like the previous TrueSil Silicones from Spectroplast. Unlike extruded silicone, which struggles with layering artifacts and surface roughness, TrueSilX50 provides an ultra-smooth, precise, isotropic finish, eliminating inconsistencies and delivering exceptional feature detail, even in complex geometries.

“Since our inception, Axtra3D has focused on delivering advanced, reliable manufacturing solutions,” said Rajeev Kulkarni, CSO of Axtra3D. He continues, “With our proven success in mold production, expanding into true silicone AM is the next significant step. This silicone formulation and our HPS process ensure that parts retain the mechanical and chemical properties ideal for medical devices, wearable technology, and industrial components and seals. The biocompatibility, durability, and precision significantly increase its breadth of applications.”

TrueSilX50 removes traditional manufacturing constraints, and our early customers have indicated it to be an ideal solution for:
Healthcare & Medical – Anatomical models, wearable medical devices, baby care products, cosmetic applicators, vascular and organ models.
Industrial & Automation – Sealants, gaskets, keypads, waterproof enclosures, sanitary solutions for food processing, household appliances.
Audiology & Dental – Custom-fit hearing aids, mouthguards, dental appliances, ensuring superior fit, comfort, and reduced lead times.
The TrueSilX50 printing workflow has been fully optimized to ensure repeatability, reliability, and seamless production integration. With minimal post-processing requirements and no loss of material performance, TrueSilX50 provides an efficient, scalable solution for industries that require the highest level of precision, durability, and surface quality.

Axtra3D’s Lumia X1, powered by HPS technology, continues to set new standards for speed, accuracy, and material performance, eliminating traditional AM trade-offs and delivering the future of silicone additive manufacturing today.
