Any resins strong enough for engineering purpose ?

You can discuss Photo-sensitive resins, polymers, and oligomers.

@ Hugues

If you are able to order 20Kg or more at a time or cover a day or two of formulation time we can blend resins to your specs

Interesting,

Do you have specs for the strongest resin you manufacture ?

Ideally: as strong as injection molded ABS or better, low shrink (<1%), UV cured, ease of peeling on FEP,

Let us know

ABS types are not a problem. The problem you are starting out with is using bottom up projection through a vat and peeling every layer along with using UV. This limits the viscosity, solids content and curing rate of the resins and composites as well as curing depth.

There is a project that is using SLA to print laptop and cellphone cases using similar resins. These resins might become standard products in the near future.
