Um Digitalizador 3D, uma Impressora/Scanner 3D, Electrólise em casa, Corian, e Cola para Acrílico

Começa-se pelo Scanner 3D da Makerbot, que vai ser posto à venda em Outubro.
Usando um sistema de rotação do Objecto, e lendo o scan duma linha em Laser, permite-vos pôr toda a espécie de objectos prontos a serem duplicados numa Impressora 3D, ou mandados para a Net:

Makerbot Digitizer set for October release

Ben Coxworth

This March, MakerBot gave us a sneak preview of its Digitizer – a 3D scanner designed to create three-dimensional design files based on scans of physical objects. At the time, it was still in prototype form, and not many details were available. Now, however, it’s a done deal, with shipping expected to begin in mid-October.

The Digitizer features a turntable-style platform, which accommodates objects measuring up to 8 x 8 inches (20.3 cm), and weighing no more than 3 kg (6.6 lb). As the object is rotated on that platform, a camera and two lasers jointly scan all of its exterior surfaces.
After a few minutes and “just two clicks,” a smooth and complete 3D design file of the object (in a format of your choice) is automatically created. This can be used with one of MakerBot’s Replicators, or on any other type of 3D printer, to produce a physical model.

...Mas agora, tal como as Multifunções em 2D, que fazem o scan e imprimem, aparece no horizonte uma Máquina que faz o mesmo... Em 3D!
Scan, e Impressão 3D, na mesma Máquina!
E já a partir de dia 4 de Setembro, começa a campanha Kickstarter desta Máquina, mais uma daqueas Kickstarters que ameaçam quadruplicar a quantia-alvo pretendida!

AIO Robotics teases Zeus all-in-one 3D scanner and printer

Lakshmi Sandhana
A new Kickstarter project is set to launch the world's first all-in-one 3D copy machine that can scan, copy, print and even fax 3D objects. Sporting a 7-inch touchscreen and four easy to operate buttons, the Zeus is a stand alone machine that can work independent of both an internet connection and a desktop computer. So instead of running out to buy a hammer the next time you need one, you could simply scan your neighbors or have a friend fax across their hammer scan and print it out on your end.
3D printers are becoming more affordable especially with MakerBot's recent announcement about the Replicator 2 3D printer being made available through select Microsoft retail outlets in the US for a price of $2,549. However these machines only print 3D objects. The field is wide open for a machine that integrates 3D scanning, copying and faxing abilities in addition to printing and that's where AIO robotics plans to step in with Zeus.
Set to launch on September 4 at Kickstarter, the Zeus features an on-board computer and a 12-inch turntable. While there's little information available on the official site, posts made by the company on the RepRap forum, state how initial tests demonstrate the machine's ability to print at a 100 micron resolution or lower.

Home Electrolysis Kit

Go Repairs

Electrolysis is a useful skill to pick up and the beauty of it is that it's super easy to do. Electrolysis can be used to plate materials, to clean, for etching and even to produce pure forms of a material.

In this article we'll show you how to make your own small electrolysis kit. With what you'll learn you'll be able to scale up the kit if you wanted to.


A Inventables pôe à vossa disposição placas deste Material, em Preto ou Branco, com o aspecto e a textura da Perda, mas que podem levar à Máquina de Fresa CNC, à Serra tico-tico, etc.
Podem até moldar a quente!
Vejam esta maravilha:


White Corian
The look and feel of stone in a millable sheet
Corian is a non-porous, solid surface material produced by DuPont. It is made of acrylic polymer and alumina trihydrate. The sheets are colored evenly throughout and have the look and feel of smooth stone.
While Corian is traditionally used as a countertop surface, its potential uses in the design world are limitless. The material can be milled as easily as most woods. It can be cut on a band saw and sanded. It can even be thermoformed when heated to 300 degrees F, meaning you can heat and bend it at interesting angles with relative ease. You can download the technical manual below for lots of additional information on how to fabricate Corian.
Because this material is manufactured with countertop use in mind, one side of the sheet and certain edges may contain writing or scratches. We can only guarantee that one side will be in pristine condition.


E a ùltima da Inventables, e a ùltima por hoje, uma Cola que cola uma data de Plásticos, e o Corian, ao Acrílico!


Acrylic Adhesive SCIGRIP Weld-On 3

Solvent cement for gluing or bonding acrylic

This is a water thin, non-flammable, very fast-setting solvent cement for gluing or bonding acrylic. It will also bond with other thermoplastics such as polystyrene, CAB (cellulose acetate butyrate), PETG (polyethylene terephthalate glycol) and polycarbonate to themselves. It will not bond to cross linked acrylics and does not work on mirrored acrylics. The technical term to describe it would be an acrylic adhesive but commonly it might be referred to as an acrylic glue. Please note that this is the same as IPS Weld-On 3.
