Computer-Aided Design (CAD) model used for 3D printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.
Unlike stereolithography, the printing process is continuous. The inventors claim that it can create objects up to 100 times faster than commercial three dimensional (3D) printing methods. [1] [2] [3]
In 2016, developments in multi-material printing have enabled material extrusion printers to utilize ceramic-based support materials, designed for easy removal. [8] This advancement significantly facilitates the creation of complex geometries, as the support material can be effortlessly broken off after printing.
This year's Consumer Electronics Show was by far the biggest exhibition in history for 3-D printing. There were dozens of companies present, along with industry leaders Stratasys and 3D Systems .
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
Large-scale, cement-based 3D printing disposes the need for conventional molding by precisely placing, or solidifying, specific volumes of material in sequential layers by a computer controlled positioning process. [91] This 3D printing approach consist of three general stages: data preparation, concrete preparation and component printing. [92]
3D printing is used to manufacture moulds for making jewelry, and even the jewelry itself. [102] 3D printing is becoming popular in the customisable gifts industry, with products such as personalized models of art and dolls, [103] in many shapes: in metal or plastic, or as consumable art, such as 3D printed chocolate. [104]
To obtain the necessary motion control trajectories to drive the actual SFF, rapid prototyping, 3D printing or additive manufacturing mechanism, the prepared geometric model is typically sliced into layers, and the slices are scanned into lines (producing a "2D drawing" used to generate trajectory as in CNC's toolpath), mimicking in reverse the ...
