Protected: Best 2017 3D Printers Under $4000

TransMagic charts categories and performance specs in a runaway market At TransMagic we have many customers who utilize 3D printers or provide 3D printing services, and use TransMagic SUPERVIEW to generate optimized STL meshes. According to the Gartner group, ~220,000 3D printers were sold in 2015, the number doubled to ~450,000 in 2016, and we’re on track to see a factor of 15 increase to 6 million units sold in 2020 *.

Materials and Mass Properties

Materials and Mass Properties

This article will demonstrate how materials are applied to models in TransMagic R12, and how parts and assemblies can then be interrogated for Mass Properties. Mass properties are particularly useful if you are generating quotes or estimates, and need to know the weight or volume of materials for the part or complete assembly. Another common use for mass properties is to get the volume calculation for estimating 3D printing print times and material costs. The Mass Properties dialog box also provides moments of inertia and allows you to create three planes that intersect at the centroid. Applying Materials Parts should already have a default material assigned;...
CAD Atomization

CAD Atomization

CAD Atomization refers to the process of converting whole assemblies to separate, independent parts. This is a one-button process which can be used for both CAD and polygonal output. 3D printing houses can use Atomize to output all parts in an assembly to STL. If you are planning to do polygonal output, be sure to check Settings and adjust polygon density before outputting STL or other polygonal formats. This article covers various STL output settings. The Atomization process works whether you are using an assembly or a multi-body part (multi-bodied parts are single parts composed of two or more solid bodies); in both cases, parts and bodies are converted to...
Brep vs Visrep Models

Brep vs Visrep Models

What are the advantages of Brep vs Visrep models, and how do you tell them apart? Brep Models Brep refers to Boundary Representation. As the name suggests, the boundary between solid and non-solid geometry is in view here, the solid geometry being a collection of interconnected surfaces. This is a mathematically precise representation of geometry. Depending on the format and the CAD software you have in your possession, the features and underlying sketches may be editable, or the shapes may be editable – but generally speaking, if you don’t have the CAD system used to create the file, you cannot edit the features or sketches unless you run a...
Optimizing STL Output

Optimizing STL Output

30 Years of STL From a humble beginning in 1987, when STL was developed by the Albert Consulting Group for 3D Systems, the format has been become a mainstay for 3D printing and has remained virtually unchanged over all these years. The name STL was derived from STereoLithography; STL uses a series of linked triangles to roughly define the surface geometry of a 3D CAD model. General STL Optimization Guidelines Whether you’re using the STL file for 3D printing, machining, or other purposes, you’ll want to set the resolution or mesh density to meet your product or prototype requirements. If your resolution is too rough, you’ll end up losing or...
Pre-Processing for Polygon Reduction

Pre-Processing for Polygon Reduction

Pre-processing for polygon reduction is possible using polygon facet resolution settings. Since the Polygon Reduction tool starts with a default facet density, it can sometimes be useful to adjust that pre-set facet density to a higher value. More information about the Polygon Reduction tool can be found here. Change Facet Resolution Starting with a sample CAD component, you can select the model with the Single Select tool, or just “Select All”, and right click to get the Change Facet Resolution options (see figure 1): Normal: The lowest resolution option, approximately 27 segments on a cylinder or hole. Medium High: Slightly higher than normal,...
