Now it’s time to prepare our design for printing. We are going to be using a slicing software like makerbot to prepare and slice it. Before we get started, make sure that the right machine is set up. For that go up to Devices > Select Type of Device and make sure that printer is checked.
Go to Add File and because Tinkercad is a cloud application most of the time, if you are working in Tinkercad, your files are going to automatically end up in your downloads folder. Choose your design and Open.
And your object comes in already nice and centered on the build plate there. And now we just have to choose the right settings for printing.
Now we just have to choose the right settings for printing.
The first design rule for 3D printing is to avoid overhangs over 45 degrees. Overhangs within this limit can be printed without support, also save print time and material. And then your design won’t require post processing or clean up.
The second one is Thread width, a way to fix the gaps that we’ve found in the design. Thread width or a single extrusion of plastic is the building block of our 3D print. The nozzle dimension of printer and a single extrusion of plastic is about of same dimension. If you want to create a part with good structural integrity, it’s preferable that these thread widths are touching and fused together.
Here, we have these big overhangs. So, we’re going to use support material and because there’s not very much contact with the build plate.For that choose Settings and make sure supports are checked.
Lastly, choose Save Settings, and then Print. Wait for the slicing to finish. When the file is sliced, check the print preview. You can see our support’s being built underneath.
Choose Close, and Export save to a file folder on my desktop And when you want to print your file, just transfer it to an SD card and pop it into your printer to create a 3D print
