3D Printing is becoming very popular. That is good for the novice printer to get information and how to’s on the best practices in the art of 3D Printing. One of the things I would like to point out is the print orientation of objects.
There are many programs for slicing the CAD files to make them printable. Some are open source others are closed. No matter what program you are using, you still have to set the object you want to print on the print bed surface. Where the object is placed and how it is placed depends many factors, first is how much support will be used?
Second is which is the top and which is the sides? Each 3D Printer prints a bit differently. Some leave noticeable lines, while others make smooth prints, but one thing is the same- the surface facing the print bed and the top if the machine will have lines through out. There is no stopping that, but there is a way to decide which side gets those lines. Post processing helps but orientation is a great tool.
You can just load the file and slice, then print or you can put some thought into how the object will be placed on the bed and then slice and print. I always ask my customers which is the top and bottom of prints and what side will not be seen or used much, that way I can decide how to place the object. There are times when orientation won’t help at all, for those times we use acetone baths and XTC-3D coatings to remove the lines. Though with XTC, it makes the prints shiny with a hard coat, if you do one side it is best to do them all.
Once you start 3D Printing you will understand exactly what i am talking about. Always make sure you find the best possible way to print your files and make matter out of ones and zeros.
As you can see below, there was no good orientation for this 30 mm connector part but you can see the print on the left side of the pics was standing up, while the other was laying on its side.
