What Is 3D Printing?
Additive manufacturing builds parts layer by layer, unlike traditional subtractive methods that carve parts out of a solid block. In 3D printing, a printer brings a digital CAD (computer-aided design) file to life as a physical object. Thanks to a growing variety of materials and printing technologies, creating custom parts for industries ranging from healthcare to aerospace has never been easier.
Evolution Over time
- 1990-2000 New methods like Fused Deposition Modelling and (Selective Laser Sintering) emerged.
- 2010 –present 3D printing became widely accessible for hobbyists, schools, and small businesses.
How to 3D Print
Begin with a CAD (computer-aided design) file, which can be created using software such as SolidWorks, Autodesk Fusion, Onshape, ANSYS, or similar tools.
Export the design as an STL file, the standard format used by most 3D printers.
Upload the STL file into your printer’s slicing software.
Once uploaded, adjust the part’s orientation, choose the material, and set other print parameters. The software then slices the model into layers and generates the tool paths for printing.
After slicing, start the print. The object is built layer by layer. Factors such as printing technology, material choice, and part size affect layer thickness, surface finish, durability, and overall print time.
