Can FTD resin with 0.5% shrinkage be used as Peachy Juice?
After reading the forum I think current resin that is going to be used for Peachy Juice can have shrinkage up to 8%. That's a lot, especially on larger prints. I wonder, did anybody tried with current Peachy prototype FTD resin? I do not know about its surface tension, but its viscosity seems to be similar to MakerJuice G+ resin. Its cost seems to be reasonable, €45 per kg (almost 1L). By the way, what is acceptable surface tension for Peachy Printer? For example, MakerJuice G+ resin have 36.5 dyn/cm surface tension.
The reason I ask is because I'm considering to preorder Peachy Printer, but I feel hesitant to preorder Peachy Juice because of its extreme shrinkage. I realize that it can be partially compensated by software, but I think that using a resin with more than order of magnitude less shrinkage could improve print quality, especially for prints that are not small.
So my question is, will be I able to use third-party resin as "Peachy Juice", assuming its surface tension is within acceptable range? Clearly, this may require somewhat different calibration and settings, so in order for this to be possible software needs to allow to make necessary adjustments.
Also, it may be worth considering to officially reselling different resins as more than one kind of Peachy Juice (so they could be used out-of-the-box by more people), it's not just about shrinkage, resins can also differ in flexibility, temperatures they can withstand after curing, etc. Some UV-curable resins can be used to make high-temp resistant parts or even molds for metal casting.
