What is 3D printing?3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created.Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.How does 3D printing work?It all starts with making a virtual design of the object you want to create. This virtual design is for instance a CAD (Computer Aided Design) file. This CAD file is created using a 3D modeling application or with a 3D scanner (to copy an existing object). A 3D scanner can make a 3D digital copy of an object.3D scanners3D modeling softwareFor more info how 3d printing works head over to : 3D Printing Basics | FAQ | Beginner's guideUpvote
Dodecahedron. The 5 "Platonic Solids" are: Cube/ 6 square sides Tetrahedron/ 4 triangles Rhomboid/ 8 triangles Dodecahedron/ 12 pentagons Icosahedron/ 20 triangles
Tetrahedron.
A 3D shape with all triangular faces can be a tetrahedron pyramid.
They are both 3d and they both form triangles on the sides to come up and make a point
A triangular pyramid. It has triangles on its 3 sides and a triangle on the bottom for a base.
