What is Fiberglass?

Inexpensive and 11 times stiffer than ABS, fiberglass is the perfect entry-level fiber for 3D printing.

When schould I 3D print Glassfiber?

Use fiberglass composite material to print parts that are an order of magnitude stiffer than typical 3D printed objects at the most affordable price.

Flexural stiffness

3D printed Fiberglass is 11x more rigid than ABS and 26x more rigid than nylon.



What is Fiberglass material?
Extremely thin strands of glass bundled together into a fiber. Fiberglass is traditionally used in composites for boat, automobile, and aircraft manufacture.

How strong is Fiberglass?
Fiberglass has a flexural strength of 200 MPa (29.0 ksi) and a tensile strength of 590 MPa (85.5 ksi). For more information on 3D printed fiberglass material properties, check out the data sheet.

What does the Fiberglass filament cost?
A 50cc spool costs £64.00 excl. VAT and a 150cc spool is £184.00 excl. VAT.
