Markforged High Temp Fibreglass Filament CFF Spool
High Strength, High Temperature Fiberglass (HSHT) is twice as strong as Markforged’s standard Fibreglass CFF filament with a 30 per cent higher heat deflection temperature (140°C vs. 105°C).
It is also cheaper to buy than Carbon Fibre CFF, and it comes in at a price that’s not significantly more expensive than standard Fibreglass CFF, despite being a superior material.
HSHT Applications
High Strength, High Temperature Fiberglass is ideal for parts that will operate in a high temperature environment, such as near an exhaust system, however it can be used in cooler environments just as well. Its high-strength properties mean that it can replace your existing fibreglass parts for added strength. Nylon parts that are embedded with continuous strands of HSHT Fibreglass retain their strength in even the hottest environments.
What else do I need to know?
High Strength, High Temperature Fiberglass is a unique 3D printing material designed for applications where extreme temperature resistance and strength is required.
HSHT Fibreglass is available in 50cm³ and 150cm³ spools, please ensure your 3D printer is compatible before use. Using HSHT Fibreglass with a non-compatible 3D printer model will void your warranty with Markforged, so please don’t attempt it.

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.
