Three dimensional printing allows you to turn a digital 3D model into a tangible object. This article will help the computer savvy to build and print a cylinder model using CAD software. This is for those who have CAD experience but not necessarily those with printing experience. The basics of this tutorial can be applied to much more complex designs.
Identify the kind of 3D printer. Determine whether it's a Makerbot Davinci or Replicator. Then you'll need to know whether it's a layer-on or a cut away printer.
Launch the CAD software that you are going to be drawing your sketches in.
Use a tool such as Tinkercad, Google Sketchup, or Blender. Put it through the file preparation software for your specific device. (You can find this on the manufacturer's website).
Click on New, then model, then press OK after you name your file.
Save all your part files in the same folder.
Create a sketch on the XY plane of a circle, with a 10mm diameter.
Extrude out the circle in the positive Z direction to 150mm.
Press the Command Finder button on the top center and type in the command for quick access.
Export your model as a STL file to your desktop.
Then click OK for the next two prompts without changing anything.
Insert the plastic filament spool at the back of the 3D printer, and insert the filament into the heating block.
Turn on the 3D printer, and select the option to "Preheat" the printer as you import your file.
Import the STL file model into the 3D printing software that comes with the 3D printer.
A window will pop up and ask where the model should be placed. Click on absolute center as this would put the model in the middle of the printing tray.
Check the "Uniform Scaling" box on the left hand side under the Scale box. The model can be resized, rotated, and adjusted using these four left hand buttons.
Select the connected setting on the printer (USB cable or Card reader).
Select the file of your model that you would like to print.
Allow your printed model to cool for about a minute before removing it from the printer.
What about prepping the plate? I've seen some say to use hairspray, glue, or painter tape. Why is this necessary?
It is to make sure the model does not break away from the print plate during printing.
If you don't have your own 3D printer, seek out a local library––some may have a 3D printer. Or, check to see if your local high school or college has a 3D printer for use. If all else fails, then you need to either buy one yourself (which is cost effective in the long run if you're going to be making many models) or locate a local person with one.
To avoid distorting your models, draw then without any holes.
Place your model in the printing software in the middle position to make it easier to remove after the printing process is complete.
Remember to preheat the printer before you import you STL file as the heating process takes roughly 10 minutes.
When designing your model, use dimensions that your printer is able to print. If unable to sketch within the printer's maximum dimensions, design your part into multiple smaller parts.
Make sure your model is cost effective (avoid any large solid blocks).
Use a raft if you are 3D printing something with a curvature.
Have fun! 3D printing has been around in engineering for quite some time and now it's out to the masses. It doesn't matter how old you are, when you see that building arm move around your creation, it really brings a sense of accomplishment.
Wait overnight after your project is finished to touch it to make sure that it is fully cooled and safe for use.
Do not touch the heating block or the heated filament as they can burn your skin.
Do not touch the model during the printed process.
Remember to insert the filament before the printer is on as the heating block becomes extremely hot.
Never touch the build arm in the process, several get to be extremely hot and will give you a nasty burn in addition to ruining your project if you touch it.
