Here is a model of the Dream Chaser. It will be used for Orbiter Space flight simulator, but i also want to make it available here if somebody wants to 3d print it. Also i hope to get some feedback to improve it.
First rate work, will put this file in to print. You asked for improvements. The wide homebuilt 3D printers will have some problems printing the file in one piece. If you could take off the nozzles and fins to print flat that would be great. If you want to go further make it a snap print model. Snap print = add some tabs to lock in the parts. See http://www.thingiverse.com/thing:45316 for an example of a snap print.
Here's the batch I 3D printed today!
Those look great! I hope you can get the design uploaded to Shapeways so those of us without printers can buy prints!
The model you attached is one solid object. On a home printer, you generally get the option to print only the outer wall of a solid object and fill the inside with webbing. Shapeways won't do this, so the entire volume of the model will be printed. Since Shapeways pricing is based on the printed volume, the model would be very expensive. For Shapeways, you'd need to add an inner shell to create a hollow model. The model also needs some scale information. When I open the .obj file in NetFabb, it's 0.1 mm long. If you provide the length of the original, whoever wants to print it can work out the scale factor to apply to the .obj file.
Cargo Dragon uses a different berthing port (CBM) than the manned vehicles, which will dock using the "International Docking Adapter". Just like shuttle used when docking, it was smaller than the CBM was used on the MPLMs. So be careful using that for scale.
I would love to have a casting, but I have no skills in using a mold.
