Does photoresist thickness affect sandcarving detail?

There are several types of photoresist on the market, and you have to choose which one works best for you. All of these photoresists come in different thicknesses, which has a bearing on how deep you want to blast; the deeper you want to go, the thicker the material should be to withstand the prolonged blasting.

It’s important to keep in mind that switching to a thicker resist comes at the expense of fine detail, and it takes a while to learn to examine a design or logo and be able to predetermine which lines may have to be thickened to make it in a thicker resist.
