Casio Mofrel 2.5D printer makes realistic fabric and leather samples
Brittany A. Roston

Casio is the latest company to showcase a cool new technology at Japan’s CEATEC event. The company recently demonstrated Mofrel 2.5D printing, an almost-3D printer that can produce materials with a texture like that of leather or fabrics. With this technology, sheets of textured ‘leather’ and ‘fabrics’ can be printed on-demand with various designs, then colored through a separate printing process.
Whereas 3D printers produce objects layer by layer out of plastics, Casio’s 2.5D printer is able to print very thin layers onto sheets of paper. These layers mimic the texture of materials, giving designers a fast on-demand way to test out a design, including getting a real-world feel of it, before creating actual samples with actual materials.

Enquanto não se vislumbram Impressora 3D de Metal, a preços mais acessíveis, eis como se faz, para transformar os vosso objectos, em peças metálicas:


Molding metal by conventional casting methods can be an expensive, time consuming endeavor. However, with 3d printed molds and low temp alloys, it is now possible to create 3d printed molds quickly and cost-effectively as shown here. The final molded pieces can be sanded, polished or painted and withstand more punishment than 3d printed pieces will. Now, you can go from concept to CAD to metal casting in less than a day!

Se se perguntam como é que arranjo tantas boas ideias para divulgar, cá vai uma pista, uma só imagam no Pinterest leva a várias Colecções de tema semelhante, o que nos permite encontrar estas jóias, 507 Movimentos, um brinquedo rastejante, e um sem-fim de outras Engenhoquices...
É bom!


507 mechanical movements, crawl wooden toy, simple Theo Jansen Mechanism, plus 240 other Pins!

E se não o sabem, as Impressoras 3D foram feitas mesmo para isto, criar MOLDES, dos quais se fazem N cópias diferentes, por isso, aprendam como poupar tempo e dinheiro, criando a vossa própria Fabriqueta em casa!

Making a 3-D Printed Mold

I recently had a project where I needed to create a couple dozen identical foam ear shapes.  Casting from a mold is the clear solution here.  However, the ears needed to fit onto an existing product, so I knew some tweaking of the design would be necessary to get it right before I could make the dozens. I was able to use Instructables' Objet Connex printers to make my molds, based on CAD drawings I made, and after a couple tweaks I got the design right and was able to make the full run.
In this Instructable I'll share what I learned about how to draw a CAD for a mold and 3D printing it out. I will assume you have access to and moderate proficiency with a CAD system (it doesn't matter what kind). For the printing, if you want to make your own but don't have access to a 3D printer, there are many services which print for a fee, or Instructables may be able to do that for you. The actual casting I will leave out as I was using an expanding polyurethane foam, which is not a generally applicable material.

E cá vai um autêntico alívio para os vosso Sofrimento, o que fazer, quando a Impressão falha, caso por caso!
Isto é que é ser vosso amigo!

Construír Robots! E Visão para os quase cegos, uma Serra de lixar(?) Óculos de sol de frascos, e Lego das Impressoras!

Querem fazer o vosso Robot, em casa?
Aprendam com o nosso amigo DJ Harrigam, como o podem fazer, um Manual de categoria, para fazer toda a espécie de Robots:

Designing And Building A Robot
DJ Harrigan
Introduction To Robotics And Robot Making  
For a hundred years, robots, automatons or otherwise synthetic assistants have been part of our popular culture. While they’ve mostly been restricted to the silver screen, thanks to increasingly affordable and powerful electronics, making robots has never been easier. Now, if you’ve got the determination and a few bucks to spare, you can design and build a robot to your liking. Maybe even a cool MeArm as depicted in the illustration above. 
Although robotics is more accessible than ever, any robot is a complex system and requires at least a basic understanding of electricity, mechanical design and programming to create. Never fear! My goal is to explain the high level concepts that make for a successful robot as well as point to the right tools and materials that the bot builders of today are using in their designs. It is a challenge, but there’s nothing quite like taking raw materials and making them come to life. Let’s get started! 

Algo que importa divulgar por todo o Mundo Lusófono, os quase-cegos poderão VER outra vez, com esta maravilhosa Enhenhoca, por isso, cá vai a Referência:

How Does eSight Let The Legally Blind See? 
eSight houses a high-speed, high-definition camera that captures everything the user is looking at. eSight’s algorithms enhance the video feed and display it on two, OLED screens in front of the user's eyes. Full color video images are clearly seen by the eSight user with unprecedented visual clarity and virtually no lag. With eSight’s patented Bioptic Tilt capability, users can adjust the device to the precise position that, for them, presents the best view of the video while maximizing side peripheral vision. This ensures a user’s balance and prevents nausea – common problems with other immersive technologies  

Lixar como deve de ser, não é brincadeira...
Por isso, vejam só esta bela ideia para lixarem Madeira com um resultado fantástico, bem fluído e contínuo:

Sanding Saw
For those of us who collect homemade sanding blocks or need to sand around corners and curves, may I present to you this homemade bow sander.
This bow sander is great for tight, curved places and works from both top and bottom.
Maybe your great grandchildren will look at yours someday and ask, “What was that thing for anyway?

Blue Light Blocking Glasses From Pill Bottlesthe6thstar 
So recently I read an article about how wearing orange glasses at night can help you sleep better at night. I wanted to test this for myself, and being the cheap person that I am, I made my own and it took me about an hour and a half. So yeah, that's what this instructable is.

Uma pequena Maravilha, tanto para terem peças de Lego à vossa maneira, como para aprenderem como mexer no porreiríssimo Programa FeeeCad, é esta quantidade de peças de Lego que podem imprimir.

Lego bricks in FreeCADmase 
People of FreeCAD
SO.... What about to create a LEGO BRICK libary for FreeCAD :)

The aim for this projekt is learning useful stuff:

Façam a vossa Impressora 3D! E magia LED, Acabamento 3D, Peltier para Câmaras, e Craftware

Se têm acesso a uma Impressora 3D, dalguma Fablab, ou de alguém que conheçam, podem, em troca dumas Bobinas de Filamento extra, e mais uns Trocados à parte, ter esta bestial Base CNC, que pode ser uma Impressora 3D, uma Fresa CNC, uma Cortadora Laser...~
Ou as três, com 3 cabeças de encaixar!

É bom!

Cheap Scalable Arduino CNC (Plotter, Mill, 3D Printer...)

In this Instructable I'll show you how to make a cheap scalable CNC machine controlled by Arduino. My printer has a usable volume of 1500x1000x200mm. It will provide a computer controlled plate where you can add any kind of tool for your application: laser, mill, drilling machine, 3D printer head, pencil…
In order to maximize customization capabilities and reduce costs:
Most parts are 3D printed
Open source hardware / software
Tube profiles work as Rails
If you are looking for a CNC but don’t want a single purpose thousand-dollar machine, this is your project!!
Be sure to watch the video above, and if you like it please consider subscribing to my channel which has been recently created and will be updated with new amazing projects.
Before starting you should know the usable length, width and height you want for your machine. The less heigth (Z) the better.
This project is based on Allted's design CC BY-NC 3.0 

Algo fácil de fazer, mas espectacular, é este Globo LED que podem fazer, e ter a satisfação de criar, sem dar cabo da cabeça...
Claro, isto vai-vos convencer a mererem-se em mais Projectos, mas há Vícios bem piores! LOL

Make Your Own POV LED Globe

In this project I will show you how I combined a couple steel pieces with an Arduino, an APA102 LED Strip and a Hall effect sensor in order to create a POV (persistence of vision) RGB LED Globe. WIth it you can create all kinds of spherical pictures or even letters which is a definite eyecatcher. Let's get started! 

Uma Impressão 3D para uma Prova-de-Conceito, não precisa de ter um acabamento especial, mas há alturas em que o Aspecto vende uma ideia.
Para isso, ou seja lá para o que for, Montras, festas, Modelos para Arquitectura, etc. vejam bem aqui, como obter um Visual de fazer chorar as Pedras da Calçada...
Belas Dicas do Site: Let's Print 3D

Guide: How to Finish 3D Prints

While I have 3D printed hundreds of designs over the years, not once have I taken the steps to finish a single print. There are plenty of videos and articles covering the process but they are often a general overview and leave out small but important bits of information. For someone inexperienced like myself who prefers to follow explicit instructions, the artistic process can be a rather daunting task. Unfortunately I purchased my 3D Printers for costume and prop design and can’t leave them unfinished forever, where this guide will cover my successful, albeit awkward adventure into the task of post processing 3D prints. 

Não sei se não se poderá usar isto para cabeças de extrusão das Impressoras, ou mesmo para os Computadores sobrecarregados dos Engenhocas, mas já para estas Câmaras espectaculares, é uma Maravilha...

Peltier Cooling for ZWO Astro Camera

After stumbling on these two YouTube vids showing how to add cooling to an uncooled ZWO Optics Astro Cam
DIY Guide Making a Peltier cooling fan mod for ZWO ASI120MC S
Peltier Cooler for ZWO Cameras - Based on Martin Pyott's Vid
I thought I'd give it a go myself.
My completed mod is shown in the image above. 

A Impressão 3D depende em tudo duma boa traducção dos nossos belos sonhos em 3D, em GCode que produza algo de jeito.
Sem isto, é só Filamento estragado, acreditem que sei do que estou a falar...
Por isso, estes Programas Grátis, que encontram na Net, são tão importantes!

CraftWare is a FREE, fast, easy-to-use slicer software that converts your digital 3D object into a .gcode toolpath format understood by most 3D printers.
CraftWare primarily works as a slicer for solid 3D digital objects, but it is also an excellent tool for many other tasks. You can interactively manage your prints, thus reducing build time and finding the optimal build supports. CraftWare also utilizes the most impressive gcode visualizer on the market; this allows you to see each print layer-by-layer, from any angle, easily allowing you to detect any places that you may want to modify before printing. It is basically like seeing a finished print in front of you before you press the start button.
CraftWare utilizes dual channel communication for real time interaction between the software and the printer -just another great tweaking option.

Robots de Papel! E Inventores de Drones, um Móvel para as Ferramentas, Electricidad de pesos, e um fidget!

Robots de Papel! 
Isto é muito bem achado, da Industry News... 
Robots que se movem como Minhocas, e podem mover-se por aí, muito mais baratos, pequenos,  e fáceis de fazer.
Não vai passar muito tempo até que se faça disto por toda a parte, e nem sei se não vai alguém fazer uma espécie de micro Stepper, e daí uma micro-CNC! 

Researchers Make Robots Out of Paper 
A team of researchers from the University of Illinois Department of Mechanical Science and Engineering has made a pair of crawling robots, Peri and Poly, out of little more than a sheet of paper, a few 3D printed parts, and a handful of screws.
The researchers used origami paper folding to create cheap robots that move like earthworms.
Poly is 51 mm wide and uses a pair of origami towers that expand and contract when twisted to make the worm robot crawl forward. The robot has directional feet made of hard plastic and rubber. The 3D-printed toes allow the robot to slide forward while the rubber heal stops it from backsliding. This particular example of bio-mimicry was inspired by the setae on earthworms.
Peri is more than twice the size, and fully mobile. Peri is 106 mm wide and runs on batteries unlike the Poly, which is tethered to the power source. Peri also uses on-board controllers to navigate. 

Podem pôr a Míudagem a fabricar Drones, aprendendo técnicas que os vão potenciar para um futuro emprego.
É bom!
Vem com mais de 16 Missões, mas o que é SÓ isso para um Engenhocas? As aplicações são INFINITAS!

Kids can create their own custom Droid and bring it to life it with littleBits electronic blocks.
Create a Droid from scratch
Go on 16+ missions in the free app
Customize & reconfigure for new powers

Cá está uma coisa que faz falta a todos os Engenhocas e Fabbers, para arrumarem a Tralha em que se transforma a vossa querida colecção de Ferramentas e etc.
Grátis, e para irem cortar na Fablab local, que eles quererão logo cortar umas tantas para eles mesmos!

The Amazing Tool Organizer (lasercut)jasonwelsh 
Have tools? Have a desk?  OCD?
You need this!

Da Página da Facebook, Zink, vem esta ideia muito bem-vinda, usar o velho mecanismo de pesos dos Relógios, para produzir electricidade para iluminar uma casa, em zonas sem Rede Eléctrica.
Muito Bom.

The Problem
Over 1.2 billion people globally have no access to electricity and millions more have an unreliable supply. Instead they use dangerous, polluting and expensive kerosene lamps for light.
A typical kerosene lamp is made by taking an empty bottle or tin can, putting a wick in the middle, filling it with fuel and lighting. Using kerosene for lighting is extremely inefficient, dangerous and expensive, and it has extensive health and environmental drawbacks.

How It Works
Combining kinetic and potential energy, GravityLight works by connecting an elevated weight — filled with rocks or sand — to a pulley system that slowly powers a generator as the weight falls to the ground. 

Para se divertirem um pouco, fiquem com esta ideia, que é uma boa maneira de renovarem a Novidade dos Fidget Spinners:

Electromagnetic Fidget Spinner Accelerator
Fidget Spinners are little plastic toys with a bearing in the center. They are fun for a little bit, but get boring after a while due to their slow spinning speeds. There are ways to make them spin faster, but these methods involve using a bulky air compressor or an expensive can of compressed air. Luckily, I have found a cheap way to accelerate these fidget spinners to extremely high speeds with the power of electromagnetism. You can even hold the spinner in your hand while you accelerate it! I have clocked a spinner that is spinning with this accelerator at speeds up to 1440 RPM, that is fast. You can build this accelerator too, it is really cheap and really simple to build.

Uma Roladora de Metal! E Bentonite, um Isqueiro todo-o-terreno, desenho Paramétrico, e a minha Delta 3D!

Mais uma bela dica da Construindoo, canal da autoria de Igor Kipgen, este impressionante Vídeo, de uma série de Vídeos, Make it Extreme,  sobre como fazer uma catrefada de Máquinas-Ferramenta, em vossas casas!
Esta, é uma Roladora de Metal, Chapa, e Tubo, que fazem com uma Rebarbadeira, (Esmerilhadeira, no Brasil), Soldadadoras MIG e TIG, e freeamental variado.
Não há limites, com este nível de Engenhoquice...

Homemade Roller Bender

This time we decided to MAKE this CONSTRUCTION to give to our viewers the opportunity to also, try to make their own METAL BENDER at their own home through electric welding, using an angle grinder and a drill.

Para a Fundição, em Moldes sobre Areia, é preciso Areia de Fundição, claro, e eis como se faz:

Bentonite Green Sand Recipe. Sticky, Oily and Just Great!

This is my new green sand mixture. This one consists of 87% of sand and 13% of bentonite clay. And some water of course :) I think in some way it's little better than my last green sand formula which consist brown clay. Bentonite clay is very sticky and oily. It's very different from brown clay. And this time green sand is really green! :)

Este Isqueiro é um Isqueiro para levar a todo o lado, e podem fazêw-lo em casa, para vossa edificação e delícia, e para terem uma ferramenta essencial, nestes dias em que nada é certo...

Uber Lighter 2.0

Burn everything in your path with the updated, ups-scaled and most awesome of lighters
This build is easier to build, you can change the wick simply and without any fuss and ascetically, it’s a much better looking and hardier lighter (in my humble opinion). Also it's around 40% larger as well! The size of the lighter will depend on how long you make the body section. I decided to make this version even bugger than the first.
Instead of fabricating a sparker section as I did in this 'ible, I went down the easy road and brought one on eBay. I’ve also added a screw cap to the end so filling-up the lighter and changing the rope (which you probably won’t do for years) is a tonne more easier to do. Also, the lighter is all made from off the shelf parts that you can buy from most hardware stores.

O Desenho Paramétrico é aqui ensinado duma forma prática e divertida, mais uma vez um Vídeo de Maker's Muse, e ainda tem lá Links para Tutorials, na descição:

How to Draw a Geneva Mechanism in Fusion 360
Maker's Muse

In this video I'll show you how I drew the Geneva Mechanism in Fusion 360. Once you get your head around using constraints (relations) and construction lines you can create very complex, adaptable sketches with ease!

Não resisto a cá pôr este pequeníssimo vídeo, montei esta minha Impressora 3D, e ei-la a cantar...
Não aconselho ninguém a comprar Kits da China, foi um Pesadelo montar este bicho, curioso, os Vídeos são uma confusão, mas incrívelmente, têem uma boa série de Imagens 3D passo-a-passo!
Haja paciência

Eis com fazerem uma Ventnoínha estilo Dyson, porque está calor cmo sei lá o quê, e assim não levam com o "martelar" tão próprio das Ventoínhas tradicionais...

3D Printed Portable Bladeless Fan

"A bladeless fan (sometimes called an air multiplier) blows air from a ring with no external blades." Dyson is a very popular company who has utilized this technology to make a quieter fan that performs better than more traditional versions. A common misconception is that "bladeless fans" are not actually bladeless. Instead of being external, a small fan is located in the pedestal and forces air out of a thin ring.
Here I'm building a very basic model which won't perform nearly as well as the Dyson models, but will be a small fraction of the price. This small model is easily portable and can be refreshingly used in a vehicle or outside as well as inside.

Pode-se agora medir o Raio dos Cantos circulares de algo que queiram reproduzir, ou duplicar, com esta gigajoga impressa em 3D! 
Cortesia da JayconSystems, é perfeita para "reverse Engineering", e conserto, por substítuição, de peças que já não se fabricam mais:

How to Measure a Corner's Radius Using a 3D Printed Tool

The world is filled with millions of different objects all with different shapes, angles, lengths, heights, widths, surfaces, depths, volumes, geometries, etc… You get the point. There are many different ways of measuring all of these different objects. Here we will focus on measuring rounded corners on physical objects. This can be a difficult task without the right tools.
Our Mechanical Engineering Team at Jaycon Systems creates, reverse engineers, and tests hundreds of hardware projects every year, so in order to make our lives easier, we came up with a simple 3D printed tool to help measure the various radii (believe it or not that is the plural of radius) of the things we work on. We hope we make your life easier as well by making these files available to the public.

Cá temos uma Fresa CNC, mesmo a puxar pró grandinho, que pode estar mesmo a calhar para alguma Oficina de Garagem, por aí...
Um Sonho realizado, para muitos.

Build Big Cnc at Home 3x2m

So why this should be of any interest of yours?
This machine was build without any special tools, basicaly drill, clamps, saw and meter would do. Of course there is more, like drill bits or, taps... but i built this one without having even a proper table.
Machine was designed to use as few part as possible and to be as precise and strong as possible, also speed was desirable as i wanted to use it with plasma, then i also wanted to be able take the machine apart, build it from localy available components so no premade table parts are needed to make the build, and after all this this machine still needed to be nice and square. Weight of some components and force distribution was also thought over.
At the end here are some realy interesting solutions for problems i delt with, worth to check out, at least i believe so.
