Photocentric Firm Grey UV resin are designed for printing hard objects were yo need a little bit of flexibility. Depending upon the thickness of the object designs printed with Photocentric Firm resin will have medium to high tensile shear properties with limited elongation. Objects can be bent slightly with extreme force and thin objects will compress and deflect enough to bend and return.

By using their firm resin you will benefit from fast exposure times with a wide exposure latitude so that you will achieve good results over a wider range of exposure conditions. The other great benefit is the price! Photocentric hard resin is considerably cheaper than comparable UV SLA or DLP resins. So get great results at a great price.

About Photocentric UV resins

Photcentric’s UV resins are designed to work with a wide range of laser printers accommodate both open and closed mode resin profiles. Their UV laser resins are formulated to work at 405nm and so can be used with popular laser printers like the Form 1+, Form 2 & Moai . For lower powered printers their DLP range of resins should be used as these can operate from 380nm-405nm. Photocentric UV resins come in a wide variety of material properties: Hard, Firm, High Tensile, Flexible and Castable formulations.
The solid material is tough, durable and long lasting provided it is stored in dry conditions away from strong UV light.

Processing instructions

Follow the procedures laid out in your 3D resin printer ́s user manual. Polymer should be poured into the tray away from direct sunlight. Polymer can be reused but should be poured through a filter to remove solid lumps. Keep hood on at all times. Liquid polymer is soluble in water and soap. After cleaning, objects surface tack can be removed by leaving under water in UV for 20 minutes or longer. If any surface tack persists you can remove it by wiping the parts with IPA.
