![]() ![]() For example, using a set of 360 degree photographs to create a 3D printed object of a persons’ head. In some instances, multiple photographs of an existing object can be used to create a 3D replica or as the basis for the new digital file. Similar to 2D printing, CNC milling and other modern technologies, a designer creates the digital representation of the object using a software program or other means. This smaller the diameter, the finer the resolution of the finished product. The nozzle diameter at the head determines the minimum amount of material that can used in the 3D printing process. This layering has an added cost benefit in that objects can be built for structural strength without having to be 100% solid (e.g., a honeycomb internal structure).Īnalogous to an electric glue gun, inside the 3D printer, plastic filament travels through a tube to the print head, where it’s heated to a semi-liquid state and extruded with precision. In 3D printing, the process begins with an empty space and layers of material are successively deposited on top of each other to build to the desired shape. In the latter, the process begins with a block of material which is larger than the finished product and is gradually reduced until the desired shape is reached. Note this is different from subtractive processes like milling and sculpting. Ī brief explanation of 3D printing – this is an additive manufacturing process for creating three dimensional (3D) solid objects from a computer model.
