A RepRap Family Tree: Tracking the Printers That Started it All. 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.
Take a look at the table below to find the perfect group for you. How Does Generative Design Unlock Engineering Innovation? · Wevolver. 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. There is a widespread belief that using a 1.8° motor at half stepping will produce the same accuracy as a 0.9° motor at full stepping.
With accuracy and smooth motion being the main advantages of using 0.9° motors, this belief leads some to think that the 1.8° motor at half stepping will be sufficient and available at a lower price.

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. A design sprint helps teams filter ideas and gain clarity as to which of them are best to pursue.
Let's dive in and see what that process looks like at a high level, and how to implement it. For more a more detailed, step-by-step process, check out Jake's book. Preparing for the Sprint To kick-off a design sprint, your goal is to assemble a diverse team from within your company of five to eight experts in different areas of the business.
Here's how the five day sprint plays out… What are the technical and market risks? The best handheld Scanners for Professionals. ROBO 3D User Forum. Bibliocad.

All three techniques provide a starting point for your model, but they have different uses and advantages. Rafts A Raft is a horizontal latticework of filament that is located underneath your part. Rafts are used primarily with ABS because they provide separation between the part and the heated bed. This separation helps to minimize uneven cooling that could cause warping or uneven shrinking on the bottom layers of your model. In this example, we will add a Raft to the popular “Dodecahedron” model. Import the STL model file ( a ProcessDouble-click on the Process to open the FFF Settings window (or click Edit Process Settings)Click Show Advanced (if it is not already visible)Click on the Layer tabPlace a checkmark beside Include Raft The Raft Settings dialog box provides four ways to modify the construction of your raft: Raft Layers gives you control over the height of your raft.
