I bought 1L of Gray Nex resin through Matter Hackers. I just finished the first 500mL bottle, and found out the second bottle is a completely different material. The first one was opaque dark gray, and had pretty good toughness and flexibility. The second is slightly translucent with less gray pigment. It also seems much more hard and brittle. Shrinkage seems to be more extreme as well.
My question is: Which one is the real Nex? If Nex is the dark, tough material from the first bottle, I will order more in the future. If it’s the translucent brittle stuff, I will look elsewhere.
