Imprimir em 3D, Ferro-Magnético, Gravar em Laser, Impressão em Papel, MAS, em 3D, e Engrenagens Cónicas no Tico-Tico!

Podem agora imprimir nas vossas Impressoras 3D em Material Ferro-Magnético, o que abre toda a espécie de novas possibilidades, como Sensores, relays, e Motores magnéticos, tanto dos rotativos, como dos Lineares!

Functional 3D Printing Looking Attractive with New Magnetic Filament from Graphene 3D Labs
Graphene 3D Lab Inc. has already demonstrated some success with the release of their Conductive Graphene Filament, which at least one of our team members thought was fun to play around with. Now, the Canadian company is introducing yet another functional filament and, this time, it’s sure to attract some attention. Currently for sale on the company’s online store, BlackMagic3D, and on Amazon is Graphene 3D Lab’s all new Ferro-Magnetic PLA filament. 
As must as one might like to create fridge magnets with the material, the new magnetic filament from Graphene 3D Lab can actually be used to make functional objects like sensors, mechanical actuators, and motors.  I won’t pretend to know how to build these, but there are plenty of tutorials online describing how to make magnetic motors, sensors, actuators, and more.  Combined with conductive filament, we are slowly approaching the day in which all the parts necessary to reproduce a 3D printer will be 3D printable, fulfilling the dreams of RepRap founder Adrian Bowyer.

Com o dinheiro que fizerem, bem podem comprar depois uma máquina mais potente!

Arduino Laser Engraver Wood Design!
Hi everybody, my name is Michiel and I am going to show you how to make an awesome looking laser engraver!
A couple of months ago, there was a CNC challenge here at instructables, while checking out the entries of that contest, I saw some pretty cool engraving machines and I thought: "Why shouldn't I make my own?". And so I did, but I didn't want to make someone else's project, I wanted to make my own. And so my story began... :)
This laser engraver uses a 1.8W 445nm laser module, of course, this is nothing compared to the industrial laser cutters who use lasers of (a lot) more than 50W. But this laser will do well for us. It can cut through paper and cardboard and it can engrave all kinds of wood. I haven't tested other materials yet, but I'm sure it can engrave many other materials. l will let you know! It has a large engraving surface of about 500x380mm.
Who can make this laser engraver? Everybody, if you are an engineer, a lawyer, a teacher or a student like me, you can build this thing! All you have to do is follow this instructable. 

Para Modelos e Maquetes bem realistas, mas numa máquina acessível, esta nova Máquina da Mcor vem-vos ajudar, agora ainda mais, porque vem com uma data de truques novos!

This 3D Printer Builds Full-Color Paper Models!


Traditional desktop 3D printers use melted plastic as their build material, but Mcor's printers layer sheets of paper on top of each other to create their models. We check out the new Mcor Arke, a printer that cuts from a large spool of paper, glues those sheets together, and then prints color on them to turn digital files into large paper models!

235 Dólares, e feito em 7 horas, não há razão para não tentarem!

How to assemble very cheap 3D printer
3D printing is great tool, you can print almost everything that you need. For example my lamp was broken since few weeks but now I design part that I needed to fix it and it works!
Cheap printer maybe mean for somebody bad printer. But I think that for this price ($235)it works great. It can print offline, has heated bed (without glass table but I will show you how to make it). Assembling it is very easy. I made it without instruction (I didn't check SD card, on it you can find some video tutorials). It took me 7 hours to build, calibrate and print first thing (small 1cmx1cmx1cm cube). 

..Mais esta, como, com a vossa humilde Serra Tico-tico de Bancada, podem fazer Engrenagens Cónicas, as tais a 90º!
Para quem queira fazer maquinetas em Madeira, isto é indispensável... 
E até vem com os Planos para o Helicóptero que aqui vêem!
É bom!
