Flexible Flex80 Transparent Clear resin
Prusament Resin Flex80 Transparent Clear is a rubber-like 405 nm UV resin with a hardness of about 80 Shore A for soft yet durable parts from MSLA printers. The manufacturer compares the flexibility of the prints to a car tyre, leather or the rubber sole of a shoe.
The resin has a noticeably weaker smell than many flexible resins and a viscosity that lets you wash finished models in isopropyl alcohol without special procedures. On the Original Prusa SL1S SPEED printer, a 0.05 mm layer of this colour version is exposed in 5 s.
- Elongation at break of 60.25 % after curing
- Low viscosity, so the resin does not need heating
- Free of bisphenol A (BPA)

Botland is a reseller of Prusa 3D printers in Poland. Buying from us means original equipment from a warehouse inside the country and fast technical support. We also offer a professional service in Poland and original spare parts.
Is it a good choice for you?
A good choice if:
- you print transparent flexible prototypes and functional parts
- you need medical models or organic structures with good flexibility
- you have a 405 nm MSLA printer, ideally the Original Prusa SL1S SPEED it was made for
Consider another option if:
- you need rigid, hard details: choose Prusament Resin Model+
- the print has to carry high tensile loads, as the tensile strength is 8.87 MPa

Did you know?
It hardens with curing
An uncured Flex80 print has a hardness of 75 Shore A, rising to 82 Shore A after UV curing. Tensile strength increases from 2.1 MPa to 8.87 MPa and elongation from 26.25 % to 60.25 %.
Frequently asked questions
How flexible are Flex80 prints?
Cured prints have a hardness of 82 Shore A and an elongation at break of 60.25 %, a flexibility Prusa compares to a car tyre, tendons or the rubber sole of a shoe.
Will Flex80 work in other printers?
Yes, the resin works with most third-party MSLA 3D printers, although it was made for the Original Prusa SL1S SPEED. On the Original Prusa SL1 a 0.05 mm layer of this version is exposed in 15 s, on the SL1S SPEED in 5 s.
How do I set up supports for Flex80?
The manufacturer recommends denser supports (200 %) and a support penetration of 0.6 mm, and the high viscosity profile if printing problems occur. The best results come from the profiles built into PrusaSlicer.
