Hard Grey UV resin


From: £66.00 (£55.00 + £11.00 VAT)

Photocentric’s Hard Grey UV SLA or DLP photopolymer will produce highly detailed parts that have very low elongation, do not bend or compress with high tensile shear properties.


Photocentric Grey UV resin comes in two forms, the UV laser resin is compatible with higher powered UV laser SLA printers and is optimised for 405nm whereas the DLP version is compatible with lower powered DLP printers at 380-405nm (Make sure you select the correct type). Their Hard UV photopolymer is ideal where hard objects are required that will not bend or compress. They have very high tensile shear properties and have very low elongation.

By using their hard 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.

UK Shipping

  1. Free UK Mainland Shipping on orders over £100 (incl. VAT); Free Highlands & Channel Islands on orders over £100 (incl. VAT).
  2. Free UK shipping on 3D printer filament samples.
  3. £5.40 (incl. VAT) flat rate for all UK Mainland orders under £100 (incl. VAT); Flat rate of £15.00 (incl. VAT) on Highlands & Channel Islands on orders below £100 (incl. VAT).

Orders over 2kg in weight are shipped via DHL Express orders under 2kg are shipped via Royal Mail 48hrs Tracked. The advantage of flat rate Postage and Packaging to our customers are that if you order 1, 2, 3, 4 or 5 spools of filament the price is the same. p.s. Were sorry about the Highland & Islands shipping costs, it’s a reflection on the increased shipping charges we have to pay.

International Shipping

We do ship internationally but ask if you can contact us to arrange an order as shipping costs can vary greatly depending upon destination and weight. Please see or International orders page for more information.

Firstly, if you want to return a product or you have a faulty product please get in touch as soon as possible! To prevent ordering incorrect items, if you are unsure just ask and we can offer some guidance. However, bear in mind that we cannot say whether a particular product will be right for the purpose that you intend to use it for. You can return your goods to iDig3Dprinting for any reason within 14 business days following receipt at your delivery address as long as they are in a re-saleable condition. Filaments & resins cannot be returned once opened as once exposed to air these items perish. Downloadable goods and 3D print samples cannot be returned and no refund will be issued. Shipping costs of returned items are paid by the customer A full refund will be issued for unopened items that are returned in their original packaging that are in a "as new" re-saleable condition minus additional costs that are incurred by iDig3Dprinting like payment processing fees, custom duties or charges. We are afraid we cannot issue refunds for products that have been defaced, altered, used, or damaged in any way. All requests for refunds are subject to inspection by iDig3DPrinting of the returned item. We are not a charity or a lending library. Refunds and returns for faulty items works a bit differently. Faulty goods can be accepted for return upto 60 days from receipt of the goods (However we prefer to offer diagnostics and repair solutions prior to an actual return, its better for the environment). After this time you will need to contact the Manufacturer. A repair or replacement will be issued for faulty goods once they have passed inspection and been found by iDig3Dprinting to be faulty. This is a brief account of our returns policy. For the full terms please see our Terms and conditions page. Content on the Terms and Conditions page supersedes this content.

How to raise a return request

  • email idig3dprinting at and we will issue a Return Authorization Number (RAN).
  • send the goods back in their original packaging.
  • Once we receive the goods back we will then check them and if everything is as it should be be will issue a refund.
  • If appropriate Refunded payments will then be issued using the original payment option. The time it takes to land in your bank account is determined by the payment gateway used not us.

The main thing is please communicate with us. We are not omnipotent! We can be quite flexible but this is built upon a foundation of mutual respect between our customers and iDig3Dprinting.

Fantastic service. Goods received within 24 hours of placing order. Will be purchasing more stuff. Would definitely recommend.
Great service, very quick to answer queries and resolve any problems. Reliable and affordable.
First class service and support, purchased some spare parts for my printer and they were glad to help with an unrelated problem I was having with the printer, even though it was not supplied by iDig , I would recommend them without hesitation.
Have had a lot a of problems setting up a 3d printer at our school, idig3d printing contacted me through a forum and have been brilliant ,giving advice and guidance. Thank you
