Fabricação

No que diz respeito à Fabricação dos vossos objectos, eis uma conversão duma máquina de Loja numa máquina de Maquinagem CNC:


Não se esqueçam de ler as perguntas e respostas neste Vídeo no Youtube, são muito esclarecedoras.
E também não me esqueço da origem desta notícia, veio daqui:

Da Makerbot, uma nova e maior Máquina de dois extrusores, para Impressão 3D a duas cores, ou dois materiais, notícia da Ponoko:



MakerBot announces new Replicator dual extrusion 3D printer for pre-order
with bread-loaf size build area!

MakerBot has announced the latest model to their line of personal 3D printers, and this one’s not a kit. The new MakerBot Replicator™ is a fully assembled desktop 3D printer that lets you print 2 different materials or colors in a single design.
It features a wider shape and a larger print area. It also comes with a new MakerBot Strepstruder for extruding ABS or PLA plastics, and you can choose either a single or dual extruder version.
Bre Pettis, CEO of MakerBot, will show off the Replicator at CES tomorrow. But you can already pre-order the Replicator starting at $1,749. (Well, you can whenever their site recovers from the traffic crash.)

Da única e inegualável Mindsets, uma máquina do caraças, entre outras coisas porreiraças, este bólide de monocarril:
This amazing system has been designed to put the WOW into a range of STEM activities. Using a simple friction drive principle, small electric vehicles, running on an electrified rail, can achieve astonishing acceleration and speed from a standing start. The rail concept has parallels with both large-scale linear rail transport systems and small-scale goods transfer lines used in manufacturing - and offers pupils or students unlimited opportunities to learn through a highly motivating and enjoyable technical challenge.
The system has two parallel rails so that vehicles can compete and their performance compared. The rails consist of plastic strips, with an aluminium tape conductor either side, secured and connected by springy metal fishplates. Practically any length can be built up and – given sufficient ground area – can be formed into a circular track. The track can be energised from batteries or a PSU, but a custom-made dual rail controller has been developed to provide speed control, kick start function and an automatic acceleration and run program for competitive racing.
The vehicles consist of a flat chassis plate running on the top of the rail and driven by two DC motors whose silicon tipped spindles engage directly with the track to provide drive. This is the principle that gives such impressive performance.
Puro génio, dois motores do mais simples, um chassis em Fibra de Carbono, e dois contactos de cobre, de onde vem a electricidade, através do monocarril!
