Formlabs (Form 3) Flame Retardant Resin 1KG (0.84L)
Drive innovation more quickly, safely, and efficiently with Formlabs’ new self-extinguishing and halogen-free SLA material with a UL 94 V-0 certification and favourable flame, smoke, and toxicity (FST) ratings. With the UL 94 V-0 and FAR-rated certification, you can produce 3D-printed parts that meet your necessary certification requirements for entering hazardous environments.
Create stiff, creep-resistant and functional parts with a 2.9GPa modulus and 112°C at 0.45 MPa HDT material that will perform well long-term in indoor and industrial environments with high temperatures or ignition sources. You can produce parts that can handle additional post-fabrication operations such as tapping, machining and drilling.
FR Resin on the Formlabs SLA ecosystem unlocks all of the benefits of scaling and automating production with the Form 3 series hardware.
You can also produce flame retardant parts that resemble the look and feel of injection moulded parts easily and affordably.

Are there special workflow considerations for FR Resin?
Shake the resin cartridge vigorously while rotating occasionally for at least 2 minutes before starting your first print.Not doing so may affect the flame retardancy properties of your printed parts. If it has been more than 2 weeks since your last print, shake the cartridge again for 2 min and stir the resin in the tank before printing. The resin is viscous, so allowing it to automatically dispense into a new tank for the first time before printing will result in a printer time-out error. Instead, please follow the instructions for manually pre-filling the resin tank before printing Priming a Form 3: Unscrew the vent cap at the top of the cartridge and manually pour around 350ml of the resin into the new resin tank b.Priming a Form 3L: Unscrew the vent cap at the top of the cartridge and manually pour the contents of one full cartridge of resin into the new resin tank

PALLETS DON'T SHIP VIA DPD - WHAT YOU NEED TO KNOW
Some units can only be shipped safely on a pallet due to weight and/or size. Cut off time for orders shipping by pallet is 1.30pm, that’s because we need to book the job before 2pm.
Pallets are big and they ship on big lorries! If there is any problem with a dustbin-lorry size vehicle accessing your property, you need to let us know and we can request delivery by a smaller 7.5T lorry. If this is the case, then PALLET NEXT DAY may not be available.
Depending on your postcode your options at checkout will include PALLET NEXT DAY, PALLET 2-3 DAYS, PALLET COLLECTION HG4 2RN (organise your own pick-up). Some postcodes will show “PALLET 5-6 DAYS” etc.
Pallet deliveries are between 09.00 and 17.00 and we are unable to give you the ETA in advance.
We use a very reliable local supplier, and the pallets go in to the “Palletforce” network. Currently the network don’t use tracking numbers and you can't track online (coming in 2026). Call or email us to check on a delivery or collection.
