SLA 3D Printing Problems: Nothing is Printing

The 3D printing gods look unfavorably upon you. You’ve half an hour spent meticulously placing supports to try and ensure success, but now nothing is even sticking to the print plate. And the injustice of it all? You probably had to wait hundreds of layers to even tell.

A Duct Tape é uma bela duma solução para uma data de problemas à volta da Oficina, mas com este catrapázio, a vossa vidinha é ainda mais facilitada, é só puxar, cortar, e já está, sem terem de ir buscar um cortante, nem terem de sequer segurar a coisa!

É bom.

Duct Tape Dispenser
ThomasVDD

Duct Tape is an indispensible tool for every maker. It is strong, it sticks like crazy and it’s easy to cut. It would be even better if it had a holder, such that it is easy and convenient to tear off a piece. That’s what we’ll build in this Instructable!

Design Made Easy With Inkscape Vector Tutorials

Shannon Birt

How To Use Inkscape Like A Pro
Want to design products but don’t have the budget for expensive software? Or do you simply like the ethos and flexibility of open source software? Inkscape, a professional vector graphics editor for Windows, Mac OS X and Linux, is a great tool you can use to design products for any number of applications, including laser cutting. And the best part? It’s open source—and FREE.
When designing products, vector graphics are critical because they maintain quality when saved and scaled. Additionally, software that creates vector paths can export both visual artwork and files to be machined. This kind of multitasking is awesome!
While Inkscape is a good alternative to paid programs such as Adobe Illustrator, it may require a bit more time to learn than its counterpart. To help you feel comfortable understanding Inkscape basics, we’ve created this guide to walk you through how to use Inkscape for design projects.

3D Design for 3D Printing
tinygeek

If you're going to have a 3D Printer, you have to be able to design things to print with it. Thingiverse can only take you so far, you know. The only problem with Makerbot/RepRap style 3D printers is that they have limitations. Some overhangs can't be printed, layer delamination can cause parts to break, etc. My goal in writing this article is to create a guide for how to design around the limitations of this type of printer to create strong, functional parts.

Nexen Enhances Roller Pinion System With Increased Torque Capacity

Editor Design World

Nexen Group, Inc. has improved its revolutionary Roller Pinion System (RPS) by significantly increasing its torque capacity. With up to 60 to 140 percent more torque capacity*, the RPS offers industry-leading power density for precision linear motion control applications.

“In the past, the market has used the phrase ‘power density’ to differentiate similar motion control solutions,” said Tony Kliber, Lead Project Engineer Precision Automation Components, Nexen Group, Inc. “The new torque capacity ratings eliminate this factor, allowing our customers to reduce the size, cost and weight of their machines without sacrificing superior linear positioning performance.”

Nexen’s RPS offers linear positioning with zero backlash for high-precision motion control applications. With more than 99 percent efficiency and a long operational life of up to 60 million pinion revolutions, the RPS yields up to 36 million meters of travel. Differing from a traditional rack and pinion system, the RPS features a roller pinion/toothed rack combination. The pinion is comprised of bearing supported rollers that engage a unique tooth profile. Each tooth profile is measured to ensure high positional accuracy and eliminate cumulative error. Racks are available in standard 1-meter and ½-meter cut lengths or can be custom cut to certain lengths, leaving no limit to travel distances.

Dos nossos amigos da 3D Printing, vem esta Dica, uma série de Livos Antigos, que ainda hoje são úteis, dos quais, The Boy Electrician, e The Boy Mechanic:

Public Domain Technical Books

This is a scanned version of The Boy Electrician, 1913 version. This book is in the public domain. Currently it is in scanned form, but the eventual goal is to use OCR software to convert it to real text plus images. If you need the original TIFs (which are huge), send me an email.

The Best Gingery Lathe Video Series To Date

Gerrit Coetzee

Makercise] has been working on a Gingery Lathe since September last year. His videos on the process are by far the most detailed, clearly shot, and complete series on making a Gingery lathe we’ve come across.
For those who aren’t familiar, the Gingery series of books describe how to build an entire machine shop’s worth of bench top tools using only the hardware store, dumpster dives, charcoal, and simple skills. The series of books start out with the charcoal foundry. [Makercise] has built a nice oil fired foundry already so it’s off to the next book, Gingery 2, is the metal lathe.
The Gingery books and, really, most DIY books from that era are: not well laid out, well written, or even complete. All but the most recent prints of the series still looked like photocopies of typewritten documents with photos glued on. The series provided just enough detail, drawings, and advice to allow the hobbyist to fill in the rest. So it’s really nice to see someone work through the methods described in the book visually. Seeing someone using a scraper made from an old file on aluminum to true the surface is much more useful than Gingery’s paragraph or two dedicated to the subject.

Our 10 best tips to identify 3D printing opportunities for your business

Amandine Richardot

Additive manufacturing can be a great asset for your business. It can truly help your company in becoming a true market leader. But, just like any great tool, it needs to be used in the right way. Indeed, using 3D printing is surely an asset, but not in all cases. Deploying a well-planned additive manufacturing strategy can help you reduce costs, build better products, and optimize your whole production process. You can use this technology for prototyping, of course, but also for production. But how can you know when it’s relevant or not to use 3D printing? Since Sculpteo was created, we got to observe numerous usages of additive manufacturing, and here are the best tips we can give you on how to identify 3D printing opportunities for your business.
