Low-cost desktop injection moulding
Janie Barrett

Low-cost desktop injection moulding - here, Mitchell Brown from VERT Design, explains how they did it using Asiga's desktop 3D printing solution ...
Our product design company was engaged to develop a variation of a hose clip that is used on a high speed production line. The product works through the use of an integral hinge and flexible clipping geometry.
Traditionally we would test the design through the used of SLS 3D printed models, however, the results achieved were not accurate. We required the geometry to be proven in the actual production materials, which in this case was injection moulded polypropylene
Through the design phase, we developed multiple iterations. Eventually this was short-listed to two possible concepts. Producing a prototype tool in steel or aluminium would have cost many thousands of dollars and taken a minimum of 6 weeks. We turned to 3D printed tooling as it was faster and cheaper.

The Easy Way to Design Gears in Fusion 360
Desktop Makes

One of the first things I ever made from a 3D printer was a gear. But it wasn't just any old gear. The beauty behind this gear was that it was a replacement part for the very printer that was making it. This still blows my mind to this day. I love printing gears and still get excited about this new world that 3D printers have opened up. The problem is that designing gears have always been a bit of a challenge for me. That is until I learned what I'm about to teach you.
In the last step I also include a video demonstrating the entire process.

If you think knitting and crocheting are only for grandmas or that macramé and woven wall hangings were just a fad in the 1970s, think again. Thanks in part to festival fashion, yarn arts are alive and well…and growing.
In fact, 38 million people knit or crochet according to the Craft Yarn Council—including celebs such as Cameron Diaz, Daryl Hannah, Julianna Margulies, Sarah Jessica Parker, Julia Roberts, Hilary Swank and Vanna White. And the Association For Creative Industries says that the U.S. creative products industries are valued at $43 billion.
There are more craft-related blogs, websites and tutorials than ever before. YouTube has 12,000 woven hall hanging videos, 400,000 macrame how-tos, 2.6 million knitting tutorials and 3.6 million crochet trainings. You could spend days on Instagram getting inspired by #bohemianstyle, #yarnlove and #makersgonnamake. Pinterest is filled with DIY yarn craft ideas. Craftsy offers lessons in 18 types of creative arts.
While these kinds of artistic expression provide a creative outlet, reduce stress, improve mood and build confidence, many makers are finding there is a business opportunity as well. On Etsy, there are 13,000 listings for woven wall hangings, 228,000+ macramé items, nearly 700,000 knitted products and 1.18 million crocheted designs.
That’s a lot of yarn.

Build Your Own Electric Car!

(AUTHORS NOTE, July 9, 2017)
Hi Everyone, there' been a lot of views on this project lately! Thanks for coming by to read through it! Much has changed since I originally built this car, including the fact that there are a LOT of great commercially built electric cars available for sale, including used at good prices. When I built this car, pretty much the only electric car available was the $100,000 Tesla Roadster. Now, I'm driving a used Mitsubishi iMiEV electric car and power it with my Solar Garage! Please take a look at my other Instructables and at for the latest on my clean transportation adventures!)

Eis algo para os Joalheiros, Dentisas, e Inventores e Engenhocas abonados, (ou Clubes deles), uma Impressora 3D, que imprime com uma qualidade incrivel, ou não fosse uma SLA, obra dum Ex-Piloto de Caças, e Inventor com várias Patentes obtidas, que cobrem esta bela Máquina:


B9Creator SLA 3D Printer 

The B9 Creator has rapidly become the preferred desktop 3D printing machine of jewelers, dental laboratories and prototypers alike. The B9 uses stereolithography to convert liquid resin into solid objects of unbelievable definition and clarity. The B9 is the brainchild of ex-US Airforce pilot Michael Joyce.  With a degree in mathematics and a passion for technology, Joyce developed multiple patented inventions which provided the basis for the very first B9 Creator.

How to Make Playdough (Play-doh

Playdough (aka Play-doh) is easy to make at home, and fun for kids of all ages.  Here's how to make your own non-toxic toy with custom colors and fragrances.

This is the classic method that involves a bit of cooking on the stovetop - I prefer it because cooked playdough has a better texture than uncooked varieties.  If you want the kids to be able to do it all themselves, try this uncooked playdough recipe.

Warning:  Keep away from dogs and other pets.  Playdough smells like people food but contains lots of salt, and a hungry dog can eat enough to cause a dangerous salt imbalance.

Para cortar por Laser via CNC, é preciso fornecer à máquina um Desenho Vectorial.

Por isso, cá vai, através da Sculpteo, uma lista de 8 Programas que vos permitem criar um desses desenhos, cortesia da Sculpteo:

Top 8 Software for Laser Cutting

With the recent launch of our Laser Cutting service, it may be interesting to take a look at some of the software you could use to create awesome designs! As a reminder, the SVG format is the one suited for laser cutting, so be careful when creating your files. Without further ado, here is our top 8 of the best Software for Laser Cutting.

Continuando na linha de fazermos algo de bem útil, com as Impressoras 3D, eis uma Lixadora de disco, que podem fazer em casa, e assim, poupam tempo e dinheiro:

Benchtop Disc Sander

Disc sanders are extremely useful tools used for rough shaping wood. When I needed a dedicated sander that could take off a lot of material at once, I was less than impressed with what was available. After not finding any disc sanders with the size and power I wanted in my price range, I started thinking of other options. Looking at what others have made in the past, most did not include a tilting work surface. This was a great design challenge that turned out better than I could have hoped!
If you are looking for your own disc sander and not impressed with anything available for the price, a homemade disc sander may be for you.

Não que os Inventores precisem de ajuda para inventar, até inventam sem querer, mas de certeza que precisam de aprender a fazê-lo duma forma mais organizada!

Por isso, cá vai uma série de Instructables, que formam um verdadeiro Curso de invenção:



This class will focus on the process of invention and how to create quality designs (products specifically) through a straightforward series of steps that provide – even for those who consider themselves to be uncreative – a path to new, innovative, well executed ideas.
Using empathy, iteration, imagination, and a dedication to problem solving (let your inner Sherlock shine!), you’ll follow along with me as I design a portable smartphone amplifier to illustrate the concepts I’ll be covering in each lesson.
Inventing is by no means a mindless paint-by-numbers process, but a systematic way of thinking – both in and out of the box – to create meaningful products that solve problems and have the potential to change lives for the better.
Let’s design a thing!
