I read an article recently that combined TPU with PLA and achieved good mechanical properties that I also needed for my project, but the problem was that this combination could not be printed with SLA or PLD 3D printing. Now I am looking to combine a hard and soft polymer like these two materials and be able to print it with the SLA method. Can you give me some advice on what materials I can use?

Dear Zahra,
what makes you think it is not possible with SLA/PLD printers? Both tough and flex resins are readily available as commercial products, or you can design your own monomer mixture.
Our latest study, for instance, compares behavior of carbon fillers in tough (Young's modulus of 1.25 GPa without post-curing, marked as "aromatic") and flex (140 MPa, marked as "non-aromatic") resins.

I remember seeing an article about multi-material using hard PLA and Silicone with a dual extruders with an interlocking 3D pattern but did not find it as it was years ago. In the search I did find this paper that may help you:

Reuben Reyes thanks for your answer but in this article used FDM method for Printing and I wanna use SLA method for printing.
Petr Lepcio Hello, thank you very much for your answer, but carbon nanoparticles are used in this article, and this combination with soft resin does not give me the desired mechanical properties, so I am looking for a combination of hard resin with soft resin.
Zahra Ghiami , sure, I understand that, but the manuscript also contains data for the unfilled resins. I aimed to illustrate that these hard and soft SLA resins exist and give you a practical example of their composition.
