I've just got my first two models in HDA, and to be quite honest, I am not impressed.

Clearly visible print lines, distortion where the model appears to have shifted during printing, and considerable pock-marking left by support structures.

One of the models was broken, either during packing or in transit, and in spite of the claims of being so much tougher than FUD resin, it seems to me so far to be almost equally brittle and fragile.

It's not very much cheaper than FUD, and in fact for multi-part models it will be considerably more expensive.

I can see no benefit to using HDA over FUD.

I am in complete agreement here. After two unacceptable samples the first chipped from support removal, and the second warped and twisted, with excess material removed from the design intent I surmise during cleaning, I have determined that I have no use for this material or printing process in my portfolio.

It may be fine for other things, but I cannot trust this product to the purchasing customers and expect that they would be pleased with the product.
