Roland DG Corporation has announced two new additions to its monoFab resin range for the ARM-10 3D printer: PRR35-OP and PRH35-ST2.
Designed specifically for the company’s desktop machine, both materials offer their own unique capabilities. PRR35-OP brings high-elasticity and rubberlike qualities whilst the second generation, PRH35-ST2, is a hard resin.
Peter Kettle, 3D Business Development Manager for Roland DG (UK) Ltd, commented: “The industry recognises the benefits of 3D printing in terms of complex geometry and detail but for this technology to realise its full potential in model making and prototyping, the material properties need to simulate the tactile nature of each component being produced. These innovations in materials technologies now allow us to print elements with varying flexibility and rigidity. The high elasticity and flexibility of Roland DG’s new rubberlike monoFab PRR35-OP resin allow us to create a more realistic, tactile experience and greater functionality. It is ideal for grips, seals and protective covers.”
The two new resins complete the set of three in total available in the imageCure range especially designed for the ARM-10 3D printer. The new resins join the “PRF35-ST” launched in October 2015: a flexible type photopolymer resin compatible, which once cured, can be sanded for a smoother finish. All imageCure resins are available in 350g bottles.

Arm-10 3D printer
The ARM-10 is ideal for quickly checking a design in the initial stage of prototyping. Incorporating a stereolithography process with a UV-LED projection system, the ARM-10 builds models by sequentially curing layers of resin from a liquid resin vat. Simultaneous production of multiple objects can be accomplished within the same work area, reducing modelling time when compared with methods where lasers expose specific areas.
Kettle added: “With the second resin; PRH-35ST2, we have updated our hard resin for simpler handling at a drastically reduced cost and with lower environmental impact. Used in isolation these resins are great but their true value becomes apparent when you combine them within one project. For example, when creating a prototype of a hand tool such as pliers with the functionality, stability and soft touch grips of the production model.”
