What is a WRL File?

Wed Jan 15, 2020

WRL files are an extension of the Virtual Reality Modeling Language (VRML) format . VRML file types enable browser plugins to display virtual reality environments. The term VRML is often referred to as “worlds” or vrml world file - which is also what WRL actually stands for.

The Main Benefits and Disadvantages of Voxel Modeling

Wed Dec 18, 2019

Voxels are to 3D what pixels are to 2D.

Firstly -- let’s examine what pixels actually are. Everything you see on your computer screen is made up of very small squares called “pixels.”

The Main Benefits and Disadvantages of Point-Cloud Modeling

Tue Dec 17, 2019

Point-cloud modeling is typically used in the process of 3D scanning objects. 

Rather than defining surfaces through mathematical formulas, or building them out of rudimentary shapes like triangles -- point cloud modeling creates a representation of a 3D object with densely placed vertices -- or “points” -- along its surface.

The Main Benefits and Disadvantages of Polygonal Modeling

Tue Dec 17, 2019

Polygonal (or polyhedral) modeling is the most common type of modeling for video games and animation studios. 

This type of modeling builds 3D objects out of smaller components called “tris” (triangles) or “polys” (polygons).

The Main Benefits and Disadvantages of BRep Modeling

Fri Dec 6, 2019

BRep modeling, or Boundary Representation modeling, is, in CAD applications, the most common type of modeling. BRep is a mathematically precise representation of a 3D object. This representation defines the geometric boundaries between solid and non-solid geometries.

What is FEA (Finite Element Analysis) in CAD?

Fri Nov 22, 2019

IN THIS ARTICLE: 

Engineers have the unenviable position of being held entirely responsible for the integrity and safety of all the products and structures they design. Small mistakes in design often lead to imminent disasters (that frequently go to court and get litigated). 

This is why products and structures go through an array of stress testing and optimization before being deployed in the real world. But doing so over hundreds of iterations (and to scale) can be prohibitively expensive. So engineers often look to simulation modeling techniques (like Finite Element Analysis) to automate and simplify this testing.

This helps to reduce the use of materials for iterative prototyping, which would otherwise be used in actualization. 

Finite element analysis is one of the most common techniques used by engineers and CAD designers to simulate “stress” on their designs.

FDM vs SLA: Which 3D Printer Type Should You Use?

Tue Oct 8, 2019

In the 3D printing and additive manufacturing space, the two leading 3D printing technologies are Fused Deposition Modeling (FDM) and Stereolithography Apparatus (SLA).

Managing Data for Today’s Additive Manufacturing Workflow

Wed Oct 2, 2019

As manufacturers begin to rely more and more on additive manufacturing (AM), moving from a few select piece parts that are 3D printed, to hundreds of assemblies in complex systems, a cohesive methodology is needed to manage this transition and associated workflows. Companies have tried to deal with these complexities and challenges with point and home-grown solutions, trying to adapt legacy systems to the new reality.

Key 3D Printer Programming Requirements

Mon Sep 30, 2019

3D printing has emerged as a popular 3D model fabrication option. Be it prototyping or showing off proof-of-concepts, or using additive manufacturing at scale.

However, effective 3D workflows rely on several key parts. First, you’ll need to use the right 3D printing system for the task at hand (i.e., FDM vs. SLA). Second, the 3D printer must have the right programming in place to read/interpret the end-user’s 3D design files.
