3D, que se farta

Eis um Post que tem Impressão 3D, que se farta, de todos os tamanhos...
Começemos pela Impressora 3D de bolso!
Esta notícia, veio pelo amigo Maurício Martis, se já não o fizeram, adicionem-no como amigo, ao Facebook e ao Google Plus.
Temos aqui,  uma boa ferramenta para Modelistas, Cientistas, Coleccionionistas, Ilusionistas, e sei lá mais quem, Joalheiros e Designers, por exemplo, obra duma equipe onde figura um engenhoso Luso-Descendente, o nosso amigo Tiago Rourke, da Diatom:

Piccolo is a pocket-sized stand-alone CNC platform. For less than $70, you can assemble your personal Arduino-compatible kit for tinkering, developing and deploying basic 3D output. Be it plotting quick graffiti, printing a one-off business card on the fly, or multiple Piccolos working together to create a large mural, this kit provides a platform for experimenting with 2D or 3D digital fabrication at a small scale. This open-source design emphasizes simplicity, and is entirely composed of digitally manufactured components and inexpensive off-the-shelf hardware.

Força, pessoal!

Um pouco maior, eis outra Impressora 3D Portátil, notícia que apanhei da Ponoko, e não a ùltima deles que cá figura:

Portable 3D printing with the Tantillus
Cute, portable, printable

RepRap aficionado Brad has designed a portable, mini-3D printer called the Tantillus. Not only is it pretty cute, it’s also capable of running on batteries!

The inspiration for the printer came when Brad found that his Prusa was too large to bring with him on holidays, and that full-size 3D printing capability was unnecessary during travel.

As expected, the build area is small (100mm x 100mm x 110mm), but actually isn’t too far off of the original MakerBot Cupcake’s intended usable build area. Also, printable extension panels are planned in case a larger print is required.

The most intriguing planned feature to me is the daisy chain option. Two printers sharing a single set of electronics could be used to mass-produce duplicate sets of prints at a reduced cost. (Like fleet of Tantillus devices printing copies of themselves, for example.)

Mais uma dica da Ponoko, este, dá para todos os gostos, e tamanhos.
Um sistema configurável ao que queiram, atenção, é só a parte Mecatrónica, sem a parte electrónica, nem extrusor, mas disso, também se pode comprar à parte, e usar uma fresa CNC, etc.

ORD 3D printer kits using MakerSlide now available for pre-order

A mechatronics kit for a clever DIY 3D printer.

The ORD 3D printer from Buildlog.Net that we posted last month is now available for pre-order. It will offered as a mechatronics kit, which means that it does not include the extruder or any electronics. These kits are intended as a starting point for your own project, not as a complete 3D printer, although there is a note on the site that a complete kit may be offered if enough people express an interest.

That being said, it looks like an excellent and highly adaptable system. The two kits are nearly identical except for the length of MakerSlide, so the system scales up and down very easily. The smaller Quantum ORD kit is projected to cost $225-$300 and the larger Hadron is expected to be $275-$350. The reservation fee for either is $30.

Homemade 2'x4' Wood CNC Router

Here I am going to show how I made my CNC (Computer Numerical Controlled) router. The table measures 24"x48" and the cutting envelope is about 19”x38.” I made this CNC when I was 17 and if you would like to see more on this CNC, visit my website at

Para acabar, sem CNC, e para a Páscoa, um Ovo da Páscoa, para o grandinho...

Giant Easter Eggs
Easter is coming soon and I hope that a lot of you will find this instructable helpful. I'm going to show you how to make giant Easter eggs out of regular insulation polystyrene. I used 100 milimeters thickness polystyrene for making 1 meter eggs. You can use this technique for making almost any round shaped object.
