Looks like you're enjoying yourself at SCAD!
I actually haven't done much drawing in the past 3 months or so, I need to get back into it because I miss it. I'm actually living in Pittsburgh now, working at an industrial design firm in prototyping/build. I do alot of metal fabrication and cad work, in order to become a designer at this firm, you start out in the build area for about 6 months then you get promoted to designer. Plus side is my metal fabrication/welding skills are getting better and better, finally learned to TIG weld and I have access laser cutters, rapid prototypers, CNC's, lathes, automated plasma cutters, and water jets for my own use when I'm off the clock and bring my own materials.
The 3D printing you spoke of is referred to as rapid prototyping, and is very cool (and expensive) stuff. We have the second most number of rapid prototyping machines in North America at work, second to Mitsubishi I believe, the machines are well over $100k+ each. Every time I walk into the rapid prototyping room, I feel like I just walked into Starship Enterprise. Ours print using layers of ABS plastic, what material does yours use? I know at VT our rapid prototyper used a sort of powder based material that tended to be brittle, we had to bondo the parts after they came out so they wouldn't be so fragile.
As far as your drawings, just keep at it. As mentioned above, some perspective would add alot, and some basic ellipse templates, french curves, etc, will aid in getting some nice smooth curves. You might want to try being a little looser and sketchy, lighten up on your line weight and search for the right line, then go over the ones you want with a graphic pen or just a heavier line weight... I used to use non-photo blue pencils to sketch, then go over with various india ink pens, prisma color markers, and pastels. Also, there are tutorials online of how to use photoshop to render your sketches, very cool stuff...I've done a few of mine and I was very happy with the results.
Maybe I'll get back into some drawing soon and post a few up here.
good luck with school, and enjoy it!
Yea, the 3D printer I was talking about is a rapid prototyper that uses ABS plastic. We have 3 rapid prototypers, a laser cutter, 2 CNC machines, 8 lathes, and a laser scanner that you can scan any object and it will digitize it on the computer in Rhino or any other program you want.
As for my drawings, I actually sketched the entire thing in pencil first. I carved out of a box, and cylinders for the wheels. I need to get an ellipse template badly, because I need some help with that. For some reason, no matter how much I practice, they are always a little bit off. They look better sketched out, but when they get inked, they look worse. The thing with me is I have no problems at all building things. I knew how to use just about all the machines in the shop before I even got here, plus I can weld. I always considered myself decent at drawing ever since I was little, but when you come to a school like this where its filled with art students, suddenly you find your work isn't nearly as good. If you have any more suggestions, or any breakdown sketches, that would be awesome!
I'll take some pics of our shop, and all the machines when I'm at the ID building next time.
