This is the first time I have gotten parts on a sprue. Previous experience suggested the machines have a way of setting down the material in a way that can create a grain. I don't have control over this, as I believe Shape ways staff manipulate the model to (hopefully) optimize printings and maximize the number of parts in a single print.
You can see the notable grain on the lower three doors. I believe these were the lower parts, as the upper parts appeared clear to my eye (and the primed part reflects this).
In the good news department, the beveled board edges rendered.
How do you get that much work out of those little guys? It's impressive! Do they hire out and if so what's the going rate? Seriously, the structure is bigger than I realized. Please keep the pictures coming. Thanks for sharing.
Keith - this is a great model - if I can offer a constructive comment, I don't know if you put in the roof trusses, but I have a few older styrene structures and it helps a lot with the long term stability of the model if to include some - simple .040" triangles work fine if they won't mess up the lighting - if you need see through, I have used strpwood trusses in styrene buildings with success if they are sealed with water based urithane.
Konrad, thanks for the tip. I am not planning on installing trusses--one cannot see them--but a couple lateral braces may be in order.
Jim warned me about soaking parts in acetone too long.
I had 3 windows that escaped painting for some reason and set them to soak last night before I went out to get some dinner with my wife. I came back and this is the result. I didn't have this issue with Bestene, but they also only soaked for 20 minutes, not two hours.
Wow, haven't seen that happen. I used to soak parts in acetone for 20 minutes (as suggested by Shapeways) but now maybe soak for 5-10 minutes. I've had narrow parts curl while soaking then flatten as they dry. Then again, I did a 3D On3 K-37 frame that kept it's shape just fine. Just be careful I guess...
I think I soaked my parts in Bestene before. Speaking with my friend, professional model builder and husband of Kelly Dunn of Dunn's Buns, Todd, he tells me that Bestene is about the weakest solvent out there. Acetone is a component of plastic: Todd was not surprised that the part warped.
After the 2013 flood, and kits under water and mud for a week, I noticed the same effect in some resin structure parts. Perhaps there was enough weak solvent in the overflowed river water to effect the resin. At the time, nobody had a theory as to why the resin warped.
