I'm putting together another Miniatures Hobby "FW" mini right now.
This Chineese knock-off is below FW's usually pretty good standard (of late- Yes Zac, some of us do get good castings from FW, don't roll your eyes!
). There are a few ~3mm airholes and a quite a lot of pin-prick airholes over the mini, as well as a couple of really bad mould slip on some detailed areas that have been a bit of a pain to clean up.
The resin is the same pale green as the last one I bought, but there are some blobs and threads of not-quite mixed properly black pigment through some of the larger resin pieces (these, of course, shall disappear with painting). This once again makes me think the original colour is a buff or light tan colour. The resin has a strong acrylic resin smell when sawn or cut, making me think that there may be some acrylic resin powder used as a filler in the PU resin. It also burns faster than FW PU.
I'd like to know the reasons for the obvious decline in the models that they are producing, The order number on the reciept from them is a few thousand more that what it was before Christmas, so perhaps they have been pushing the moulds a bit longer than they should or cutting corners in the pressure department, when the resin is curing in the moulds.
