3D printing photoresin is a type of 3D printing material made from photosensitive resin. It is utilised in the fabrication of three dimensional parts and structures through the use of a liquid ultraviolet (UV) light-cured photopolymer resin and a 3D printer.
Photoresin printing works by layer bonding (3DP), a digital light projection (DLP), or a laser stereolithography (SLA) 3D printing process.
The photopolymer resin is a liquid material that is cured into a solid state by having light shone onto it from a light source such as an ultraviolet LED.
This curing process forms a solid, property-enriched polymer that can be used to make intricate parts and objects. Photoresin 3D printing is a fast and precise process used to create strong and detailed 3D prints.
Due to its high strength, flexibility, and speed, photoresin 3D printing is useful for product prototyping and applications that require accuracy and detail.
It produces parts with only 0.05mm to 0.1mm layer thickness. This makes it possible to create parts and structures with complex designs, tight spaces, and small depths.
Photoresin has high impact strength, high chemical resistance, and is capable of lasting for many years. While its laser visibility isn’t very good due to the lack of absorbance for wavelengths at the higher end of the spectrum, it has a broad range of applications including dental restorations, prosthetics, biomedical parts, and more.
Through the use of 3D printing photoresins, professional makers, designers, and engineers can create intricate parts more quickly and cost-effectively than ever before.
The Global 3D Printing Photoresin market accounted for $XX Billion in 2022 and is anticipated to
Evonik has developed its range of photo-resins by introducing three new INFINAM photopolymers for industrial 3D applications. SLA and DLP, two popular UV-curing 3D printing techniques, are meant to be used with this product line. ‘Diversifying the additive manufacturing material landscape’ is how Evonik describes its seven new photopolymer compositions. Photo-resin for the eyeglass market is called INFINAM RG 2000 L.
According to Evonik, the transparent liquid formulation is simple to work with and cures rapidly. According to the manufacturer, the low yellowing index of the material keeps it appealing for use in additively manufactured eyewear frames as well as transparent high-end prototypes that allow users to observe the inner workings of intricate assemblies. This is especially true after extended UV irradiation.
Parts with low moisture absorption and isotropic qualities can be produced thanks to INFINAM RG 7100 L, which was created especially for DLP printers. The black formulation may be utilised on high throughput printing systems, according to Evonik, and the mechanical qualities are similar to those of an ABS material. Evonik claims that the RG 7100 L has excellent qualities, like shiny, smooth surfaces, which make it perfect for intricate design visualisations.
It can also be utilised in applications that call for high ductility and high impact strength, like buckles, drones, and automotive parts. According to the manufacturer, even when exposed to strong stresses, the pieces can be machined and yet withstand breakage.
One product development that is application-focused is INFINAM TI 5400 L. Evonik claims that it is reacting to consumer desires for a PVC-like resin for the market of limited-edition designer toys, particularly from the Asian region. According to Evonik, items with exceptional surface quality and a high degree of detail are most suited for the white material.
According to the business, the material’s surface quality is nearly identical to that of similar injection-moulded parts, and it combines “excellent” impact strength with high elongation at break and long-lasting thermomechanical performance.
