Cimento 3D! E Cortar por Waterjet por tostões, Protótipos feitos à medida, Um Robot para todos, e um Torno de Metal DIY(!)

Que tal, o vosso Laboratório, ou Oficina...
Impressos em 3D?
Foi o que foi feito em Dubai, pela Empresa Holandesa CyBe, isto é um Mundo fantástico:

Dubai’s New Drone Laboratory is 3D Printed from Concrete

Matthew Mensley 
And the award for the most “the future is now” headline goes to this story, and the news that concrete 3D printing company CyBe has completed its first project in Dubai.
The Dutch firm has been working on the city’s new R&Drone Laboratory, one of a number of progressively technology-focused projects commissioned by Dubai’s numerous authorities.
Located in the desert at the city’s Solar Park, it will be home to exciting research facility. Exciting indeed, since 3D printing will be one of the areas of focus, alongside the building’s titular drones.
The Dubai Electrical and Water Authority, architects Wanders Wagner, engineering consultants Witteveen + Bos and construction firm CONVRGNT all have a stake in the project. But it is CyBe that planned and physically constructed the structure.
To achieve this the company used its array of proprietary, concrete-based products. This includes software, material and the CyBe RC 3Dp mobile printer.

Abram os olhos, Engenhocas! 
Cortar por jacto-de-àgua, a 150 Dólares!

Há quem tenha muito Tempo e pouco Dinheiro...
Mas há quem tenha Dinheiro que chegue, mas pouco Tempo!

Para esses, e para quem tem de apresentar um Protótipo já num  nível muito mais avançado, já para a pré-producção, eis esta empresa, que vos resolve o problema:

Eis um simpático Robot Open Source, o One, e é mesmo para todos, Programadores, Educadores, Hobistas, ou mesmo os mais novos!

Porque pode ser programando com um Interface de programação intuitivo, o Scratch, ou para Engenhocas mais sabidos, em  C++, Java, PHP ou Python, vai ser uma ferramenta bacana:

The Perfect Platform for Kids, Educators and Developers
Qbo Robot One is built to be easy. It is easy to adopt because it is relatively inexpensive, it is easy to understand because it is interfaced with very simple parts and it is easy to build applications on because its hardware and software are open source.
Programming language such as C++, Java, PHP or Python can be used to program One. Notwithstanding, those with little or no programming language experience can always start with Scratch. Scratch is easy to learn, so much so that even kids can pick it up. Essentially, Scratch is supported by comprehensive and interesting tutorials together with references and discussion forums to get the learner up to speed. It is designed to be graphical so that users can just pick and drop various modules to write a program. It similar to building a jigsaw puzzle, only that this time, instead of putting an image together, the user writes a program. 

Quantas vezes já não vos falei do Torno Gingery!
Pois para vos inspirar a fazerem um, cá vai esta história de sucesso, para verem que sim, pode ser feito:

Re: Home made tools!
Here’s my ultimate home made tool. My lathe! It swings 10.5” over the bed. Turns 24” between centers. Threads the full compliment of SAE threads. Has steady and follow rests as well as a Southbend inspired taper attachment. Yep, I cut all the change gears, made most of the tooling (except chucks) including a sector type dividing head with hole plates. This little lathe still turns with +/- .001” (or better) accuracy and I still use it on occasion. I completed it back in the late 90’s and as I recall it took me about two years of pretty much devoting every spare moment I had to it. 
I was inspired by the David Gingery book Metal Lathe. The book outlines detailed plans and instructions for building a small lathe from aluminum castings. I used no castings for mine but the shop lore and techniques in this little book were all I needed to understand the processes and basic machining skills needed to complete the project. Even if you have no intention of building such a thing the book is well worth looking at. Gingery is a genius of what I like to call “bootstrap engineering”. He takes scratch building to a whole new level. He has several other project books out including how to build a drill press, a shaper, a horizontal mill, sheet metal brake, dividing head, etc.
