A few comments on some of the other posts
Flash is actually a good sign that the mold was filled completely and there shouldn't be very many, or large, air bubbles
Flash is usually caused by not enough pressure being applied to the mold thus resin seeps into the cracks
My local gw has been really good about replacing bad models
I am sure this is true. They have no up front cost to buy the models because they are the company that makes them.
Independent games stores have to pay up front and returning items take time. As the saying goes time is money.
the cheapness of the material won't offset the cost of new molds.those things are probably running upwards of $10,000 each
ahh how to comment on this one and be polite at the same time. Silcone mold for a box of Plague marines can be made for less than $10. I am sure
GW has to have multiple molds but I don't think it cost them $10k
GW also has to pay for the storage of their old metal molds. they can't sell them as that could allow people to copy their IP, so they either have to destroy them or store them. storage is better as they could need them for a rainy day.
Pewter molds are made of vulcanized rubber basiclly car tire material. Easly recyclable. As for storage cannot be enough for any impact on cost.
Did some research. Bubbles are created when the resin is mix and poured into the mold. The mold is then placed in a vacumn chamber and the chamber is decresed to as close to zero psi as possible. If you remember high school science class, decreasing the pressure cause the resin to literly boil making the air bubbles move to the top and ifthe mold is designed correctly these bubble should come out of vent holes in the top of the mold.
So 3 reasons for bubbles can be concluded
Poor mold design
To little vacumn
Not enough time in vacumn
These are all quality control issuse.
I bought a Varghulf this week. No bubbles, alittle bit of flash across the fur on the shoulder this left a slight line when I gave it the final drybrush. All in all satisfied with the quality. Put it beside my metal one and could not really see any marked improvement in detail. My freind actually picked the metel one out for better detail.
GW last week sent out thier new price list. I had some free time so I helped my buddy reprice the stock. All I have to say is I am glad I do not have to start a new army. Almost the whole
40K and Fantasy lines went up 10 to 20%. Codex $29 WOW
