If you're not familiar with the concept of a 3D pen, imagine a pen, but instead of ink coming out, you write or draw with plastic. The pen heats up plastic (technically called filament) so it comes out soft and you then use your imagination to create something with the melted filament. The filament hardens quickly so you can pick up your creation soon after drawing it. You don't want to touch the melted plastic as it comes out of the pen as that is 170 degrees (ish) Fahrenheit. Don't touch the tip of the pen either as that is hot, too.
After failing miserably the first couple times, I learned the best way to get started drawing with your Scribbler 3D pen is to find a template or stencil. You then draw all the individual components separately in 2D space, flat on the paper. Always pull the pen infront of the plastic. Don't try to push through the filament. This means as you draw a circle you either have to either stop to rotate the paper or rotate as you go along.
Once you've drawn all the individual components, only then do you try to combine them to make your object 3D. If the stencil shows the final product, make sure the pieces match what is in the stencil. If you look carefully at the top right of the bike stencil, you'll notice the bike frame is missing a piece. If the individual pieces fall apart while moving things around, don't worry about it. Just lay some more filament over the broken piece and they'll magically glue together.
The 3D Scribbler pen I got came with red, white, and blue rolls of filament which I used to make the bike components. I chose to use some clear filament I already had to combine the pieces. Otherwise I would have had to use the red, white, or blue to do that. It is at least recognizable as a bicycle. Depending upon the stencil you choose, there are some with forks and spinning wheels. Mine is stationary. I even added my own kickstand so it will stand up for the picture.
The whole bike took maybe 15-20 minutes to complete. The pen worked flawlessly and its screen is very helpful. You basically wait for the pen to heat up then shove the raw filament into one of the pen. There are buttons for forward/backwards and speed/temperature adjustment. Just keep moving the filament forward and it will eventually reach the tip where you can draw with it. When you change colors, the initial bit that comes out will be what's left of the old color. That doesn't last long, unless you're new filament is white which seems to make the transition longer.
When you're done with a particular 3D drawing, you may want to trim the rough edges with a scissor. I've also heard of placing model in microwave but I wouldn't want to risk melting the whole model vs. just smoothing out the rough edges. As you draw more you'll have less rough edges.
The Scribbler 3D pen is a really fun toy to have. Until the end of the year, you can even save $35, too thanks to a usfamilyguide coupon! - Use coupon code "usfamilyguide" during checkout at scribbler3dpen.com to get $35 off your order of Scribbler 3D Pen! Do get extra filament when you make a purchase. I haven't gone through all mine but I had previously picked up some extra rolls. Watch for the filament material, too, as there are different melting temperatures.
