For instance, a Polylactic acid (PLA) based resin would be a good start, especially if it has a high resolution for printing (e.g. printing features on the order of ~100 microns).
There are numerous sources in the literature that have successfully created and used PLA stereolithography resins, but is there a commercial product available or a place to custom order? I can't fine one. Alternatively, I could try to recreate these resins (a bit beyond my expertise) or utilize a different biocompatible material if a better option is available.
Thanks!
