  Original research from the Engineered Biomedical Materials Research and Innovation Centre (EnBioMatRIC, Manipal University Jaipur), co-authored by Juan Segurola with 3Dresyns, Resyner Technologies S.L. affiliation. 3Dresyn Biotough D90 MF (monomer-free) is used as the biocompatible photopolymer matrix, formulated with 3Dresyns Fine Tuner FT2P as photoaccelerant and 3D-ADD ROC1 (Radio Opaque Concentrate Bio) at variable loadings up to 25 wt%, with silk powder reinforcement (0.5 wt%) and silane coupling agent (0.2 wt%) to fabricate radiopaque load-bearing bone plates on a masked stereolithography (MSLA) printer. The optimised composition reached tensile strength 48.9 ± 4.0 MPa, flexural strength 86.2 ± 1.5 MPa and compressive strength 292.4 ± 8.7 MPa, with hydrophilic surface behaviour (contact angle < 90°) and radiographic visibility comparable to a high-speed-steel reference.

Hands-on resin reviews · Impresión 3D Daily

• Prueba resina 3Dresyns TFD80 — flexible, resistente y ajustable
  Detailed hands-on test of 3Dresyn TFD80 (Tough & Foldable, Shore D80) on a Uniz Slash+ MSLA at 50 µm. The reviewer notes the printed parts can be twisted without breakage and return to their original shape in seconds while remaining hard, capable of withstanding 120 ºC. The review showcases the 3Dresyns Fine Tuner FT1 (shipped free with the resin) — added on demand to drop layer cure time from ~25 s down to ~5 s on low-power UV printers — plus the auxiliary 3D-ADD NSA1 (universal anti-stick additive, compatible with any resin) and Cleaning Fluid Bio used as both solvent (3–5%) to lower viscosity and as IPA-replacement that does not embrittle the part nor smell. The reviewer explicitly highlights the resin as "the kind of resin only large manufacturers like Volvo have access to, made in Barcelona", and includes the elegant in-built cure indicator: yellow tint disappears when the part is fully cured.
• Prueba resina 3Dresyns PEEK-Like — tan resistente como irrompible
  Hands-on review of 3Dresyn PEEK-Like (LV, Low Viscosity version) for desktop MSLA printers. The reviewer characterises the resin as 100% biocompatible, implantable, food-grade, monomer-free, organo-tin and metal-free, with high flexural and impact resistance from its long-chain biocompatible chemistry. A printed mechanical hook was load-tested with a digital traction scale and the reviewer concludes: "hard, non-toxic, light, ready to support whatever you throw at it, simply incredible — like real PEEK". Recommended applications: mechanical components, functional prototypes and parts subject to high mechanical pressure.
• Prueba resina 3Dresyns UF Bio — impresiones rápidas y de fácil despegado
  Review of 3Dresyn UF Bio (Ultra Fast, Bio) on Elegoo Mars / Anycubic Photon-class MSLA printers. The reviewer highlights the resin's biodegradable, biocompatible, monomer-free, low-viscosity formulation with honey-coloured tint that disappears on curing, and tunable Shore hardness on demand. Most striking: the resin's natural-oil component allows large prints to be removed by hand from the build plate, eliminating the most common failure mode of MSLA printing. Burn-in: 120 s for the first 3–5 anchor layers on a Photon S; sold at 99 €/L direct from 3Dresyns.
• Prueba resina 3Dresyn Biotough D90 — sin olores y muy tenaz
  Review of 3Dresyn Biotough D90, a 100% biocompatible Shore-D90 resin with flexural strength of 110 MPa — described by the reviewer as the toughest resin tested to date.
