3-D Locomotive

Hello I'm a student from Prairie Ridge High School. I designed a Locomotive in 360 Fusion for this competition. In total it took me about 2 hrs for me to do the designing and another few hours to print. I broke the process down into 7 basic steps.

- 360 fusion

- Makerbot 3D printer

First I sketched a rectangle and extruded it up out of the grid. Then at the front I added an "S" curve to make the front of the train. I then cut that shape through the block to get a nice curve.

On the sides of the base you need to create the wheels. I just drew a circle that reached the top and bottom of the base and then using the rectangle pattern tool I just copied the wheel and moved it horizontally to make sure they were equal distanced from each other. You then extrude the 3 shapes out of the base. you can do the same thing on the other side nut to make sure the wheels were lined up on both sides I just extruded the same wheel through the base.

This is where you can customize your design with a unique shape. For me I just looked at some old pictures of some locomotives and got my inspiration. I made my base with two rectangles and a quarter circle. Then I extruded that base across the width of the train. Make sure its centered if you don't extrude all the way across like I did.

To make the boiler you just draw a circle so that is just pops over the top of the locomotive body. Extrude it backwards until it meets the locomotive cabin and extrude it forward until it meets the middle of the curve. After you make the boiler you want to put a rectangular prism under it to support it.

Draw a sketch and then use the 3 point curve tool to make a nice angled roof above the cabin of your locomotive. Extrude it to the back of the cabin and you have your roof.

This is where you can go wild. I added a boiler cap by extruding a cylinder out of the top of the boiler and then adding a dome on top of that. for the funnel I did the same thing but shelled it to create a hole and I also used the fillet tool to add a ring around it. For the cabin I added doors and windows by just cutting into the cabin. Finally I added a detail to the boiler support by adding a curve to it. This also a time to fix anything you didn't like before. My three wheels were a bit close together so I spread them apart on a new base that was longer. After your done you have finished the 3-D model.

I just uploaded a STL file and sent it of to our printer. It took a few hours to print and then it was done. Enjoy your 3D locomotive!
