Rafts, Skirts and Brims! This tutorial will help you understand the differences between rafts, skirts and brims. All three techniques provide a starting point for your model, but they have different uses and advantages. Rafts WebGL Inspector An advanced WebGL debugging toolkit About WebGL Inspector is a tool inspired by gDEBugger and PIX with the goal of making the development of advanced WebGL applications easier. What Firebug and Developer Tools are to HTML/JS, WebGL Inspector is to WebGL.

About PCB Panels for Manufacturing Control PCB Fabrication Costs by Thinking About Panel Sizes Getting the most for your money in custom printed circuit board manufacturing requires a little up-front knowledge of how they are made. Unfortunately, your manufacturing partner may not talk completely straight about their processes and pricing model (kudos to those that have live pricing on the websites). If you're new to the industry, or just looking for hints on how to lower your PCB costs, keep reading and perhaps you'll learn something new. Design Sprints — the Secret to Rapidly Developing Products Customers Actually Want This post will teach you the process of running a design sprint — a method developed by Jake Knapp, a partner at Google Ventures — to solve big problems and test new ideas in just five days. Most teams often invest months, even years, in developing a product or service, only to discover they've built something that no one wants. Jake developed a method that helps teams make better use of time and resources by simulating the entire product development process in just five days.

GLSL 1.2 Tutorial In this tutorial shader programming using GLSL 1.2 will be covered. Although many parts are now considered deprecated, the essence of GLSL has remained constant. Besides, this tutorial will continue to be online because learning the basics of deprecated OpenGL is easier than learning the new versions. If you’re looking for a GLSL tutorial that deals only with non-deprecated features visit the GLSL Core tutorial, here in Lighthouse3D. From the CAD Library: Padstacks Padstack creation is something every CAD tool will eventually have to incorporate because it expedites and optimizes the constructionof CAD libraries. The SMT padstack is easy to define: Top landTop solder maskTop paste maskTop assembly Last week, I explained land calculation for SMT land patterns, so let's discuss plated through-hole calculations in this segment. The through-hole (PTH) padstack is complex. See Figure 1 of a through-hole padstack.

The State of 3D Printing The largest study on the impact of 3D printing in the business

Blender 2.67 RC1 and DVD Training Blender for 3D Printing Released April 28, 2013 Open-source 3D creation suite Blender has released the first Release Candidate of Blender 2.67. Major improvements are the inclusion of FreeStyle, subsurface scattering for Cycles, optimizations in the motion tracker and the new 3D printing toolkit. The new 3D printing toolkit is a collection of useful tools including statistics, error checking, cleanup and export, to make it easier to export models for 3D printing. Practical Electronics/PCB Layout The efficient laying out of traces on a PCB is a complex skill, and requires much patience. This task has been made vastly easier with the advent of readily available PCB layout software, but it is still challenging. Usually an electronics or electrical engineer designs the circuit, and a layout specialist designs the PCB. PCB design is a specialized skill. There are numerous techniques and standards used to design a PCB that is easy to manufacture and yet small and inexpensive. Copper Thickness[edit]

Design Accuracy Comparison 0.9° vs. 1.8° Often times when an engineer is selecting a step motor for his or her application, one important decision that needs to be made is whether or not to choose a 0.9° or a 1.8° step motor. When making a decision of this magnitude, two factors will invariably come into play: performance and price. With the ever increasing role of competition in today’s motion control industry, both performance and price are major difference makers in every decision. In terms of performance the question is whether altering the way a 1.8° step motor operates will, in fact, produce a 0.9° type motor performance. Discover BEST Mechanical Engineering & Robotics Groups. Today we share the 20 BEST Mechanical Engineering & Robotics Groups for 2017 on LinkedIn. Social communities for engineers are not only great for networking, but they are possibly the greatest option for troubleshooting or receiving suggestions for improving your iterations. Take a look at our list of mechanical engineering forums & online groups to help jump start your project. Below you can find our list of the best engineering and robotics groups available on LinkedIn, many of these groups are members only, meaning that you have to join and be approved by the admins of the group. Most of the groups on this list are not hard to get into, they do not require any credentials or proof of education, you might be required to wait up to a week to be approved however once accepted these groups are a great way to network and troubleshoot issues you might face.
