Making models hollow in 3D Printing

One of the most common questions that we encounter is: How to make models hollow in 3D Printing?! So we decided that it was about time we published an article addressing this concern. Models are shelled or made hollow to either reduce the cost of the part, or to reduce weight. But more often than not, in 3D Printing, it’s…

Learn how Support Structures affect the surface finish of a 3D Printed Part

Support structures are generated in part geometries having shallow angles and overhanging features. Support structures, as the name implies, are ancillary geometries necessary to support the main part geometry in order to achieve the desired output of the latter. There are a few technologies in 3D printing viz. Selective Laser Sintering (SLS), and Color Jet Printing (CJP) where there is…

Will Additive Manufacturing replace Subtractive Manufacturing?

Additive Manufacturing(AM) or 3D printing as it is commonly called, is a manufacturing technology wherein parts are fabricated layer by layer. Since the material is added layer by layer, it is called Additive manufacturing. Essentially, you start with nothing and end up building a part bottom up as opposed to Subtractive(traditional) manufacturing wherein you start with a chunk of material…

Nylon

Nylon Nylon or PA2200 is a polyamide 12 compound. Nylon is white in color and comes with an inherent grainy surface finish. Since Nylon parts are fabricated in Selective Laser Sintering (SLS) technology, there is no support structure generation, making it suitable for parts which are complex and which have intricate geometries and moving part assemblies. Due to excellent mechanical…

Glass-Filled Nylon

Glass-Filled Nylon Glass-Filled Nylon (GF) or PA3200 is a reinforced material (polyamide-12 + 30 % Glass-Filled). GF is off-white in color and comes with an inherent grainy surface finish. Since GF parts are fabricated in Selective Laser Sintering (SLS) (SLS) technology, there is no support structure generation, making it suitable for parts which are complex and which have intricate geometries…

PP-equivalent plastic

PP-equivalent plastic PP-equivalent plastic is a resin-based material simulating the properties of Polypropylene. It is opaque in nature and comes in a milky white color. The parts have an inherent smooth surface finish. Since PP-equivalent parts are fabricated in Stereolithography (SLA) (SLA) technology, there is support structure generation under the overhanging and protruding features. Therefore, although complex and intricate structures can…

PC-equivalent plastic

PC-equivalent plastic PC-equivalent plastic is translucent (50–60% transparency) and comes with an inherent smooth surface finish. PC-equivalent plastic is a resin-based material simulating the properties of Polycarbonate. It is translucent (50–60% transparency) and comes with an inherent smooth surface finish. Since PC-equivalent parts are fabricated in Stereolithography (SLA) technology, there is support structure generation under the overhanging and protruding features. PC-equivalent…

Learn more about ABS material properties for 3D Printing service

Acrylonitrile Butadiene Styrene or ABS, as it commonly referred to, is a widely used thermoplastic throughout the industry. ABS material comes in the form of a filament and is processed in Fused Filament Fabrication (FFF) technology. ABS material is white in color but also comes in varied filament color options. Since ABS plastic parts are fabricated layer by layer in 3D Printing,…

Polyjet 3D Printing Made Simple

Polyjet Polyjet is a proprietary technology by Stratasys. Polyjet, as the name suggests, (poly=many) consists of an array of jets(nozzles) mounted on the print-head. These jets have an aperture diameter of approx. 22–28 microns. The layer thickness in Polyjet technology goes as fine as 16µm i.e 0.016mm. Polyjet process has support structure generation. These are wax-like supports which can be…

Stereolithography (SLA)

SLA Stereolithography (SLA) is the pioneer technology in the field of 3D Printing. The entire 3D Printing journey started with the advent of SLA. There are different variants of the Stereolithography technology with respect to how the parts are fabricated — top-down, bottom-up, CLIP etc. But the setup is almost same irrespective of the fabrication approach. A typical SLA setup…

Fused Filament Fabrication (FFF)

Fused Filament Fabrication Fused Filament Fabrication (FFF) is a filament based 3D Printing technology. It is one of the most widely available and one of the most cost-effective 3D printing technologies till date. An FFF 3D Printer consists of an extruder, a nozzle, and a platform. The 3D CAD file is input to the FFF printer where the software slices…

Selective Laser Sintering (SLS)

SLS Selective Laser Sintering (SLS) is a powder-based 3D printing technology wherein the parts are fabricated layer by layer. The setup consists of a laser, recoater, and a bed of powder material. The powder bed is heated to a temperature just below the melting point of the material and the entire setup is isolated from the ambient environment. The 3D…
