- 3D Printers For Sale Online in South Africa
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. They are integral part of any design system. They allow for fast prototyping and creative license. You can design and manufacture almost anything. Your imagination is your only anchor. DIY Geek’s 3D printers come in a range of sizes and performances to suit your needs. Contact us for best price and sale items.
3D printable models may be created with a computer-aided design (CAD) package, via a 3D scanner, or by a plain digital camera and photogrammetry software. 3D printed models created with CAD result in relatively fewer errors than other methods. Errors in 3D printable models can be identified and corrected before 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.
Though the printer-produced resolution is sufficient for many applications, greater accuracy can be achieved by printing a slightly oversized version of the desired object in standard resolution and then removing material using a higher-resolution subtractive process.
Traditionally, 3D printing focused on polymers for printing, due to the ease of manufacturing and handling polymeric materials. However, the method has rapidly evolved to not only print various polymers but also metals and ceramics, making 3D printing a versatile option for manufacturing. Layer-by-layer fabrication of three-dimensional physical models is a modern concept that “stems from the ever-growing CAD industry, more specifically the solid modeling side of CAD”. Before solid modeling was introduced in the late 1980’s, three-dimensional models were created with wire frames and surfaces” but in all cases the layers of materials are controlled by the printer and the material properties. The three-dimensional material layer is controlled by deposition rate as set by the printer operator and stored in a computer file. The earliest printed patented material was a Hot melt type ink for printing patterns using a heated metal alloy
