MAKERBLOCK! E o PulleyBot, poupar na Impressão 3D, e imprimir em 10 Materiais simultâneamente!

Podia só dar esta Notícia, hoje, e dava-me por satisfeito, isto é uma Ferramenta que faltava ao Inventor, ao Modelista e ao Engenhocas em geral.
Junte-se o Arduino a um Sistema de Construcção dedicado ao Automatismo e à Robótica, e teremos muita gente feliz... 
E vem com Instrucções, e tudo!
FANTÁSTICO!
Vejam a análise dum Kit, por estes Bacanos:




Makeblock, robots con Arduino al alcance de todos: Análisis

En Xataka Smart Home sabemos que os encantan las entradas dedicadas a la automatización. Hace tiempo nos contactaron de Makeblock para ofrecernos un Starter Robot Kit V2.0 para su revisión, y aquí os traemos la primera parte de nuestro análisis, en la que nos centraremos en la descripción del kit y el montaje de uno de los modelos básicos para comprobar que todo funciona y familiarizarnos con el conjunto.
En concreto vamos a construir un agente autónomo que se desplaza con un par de orugas y que cuenta con un sensor de ultrasonidos para evitar obstáculos y un sensor de infrarrojos para poder controlarlo a distancia. Y todo ello con una placa de control Arduino Leonardo que ya tiene todo lo necesario para que la construcción sea coser y cantar.
Makeblock es un sistema de construcción de elementos basado en Arduino, con elementos tales como actuadores, motores, interruptores y hasta controladoras bluetooth. Todos estos módulos electrónicos son de código abierto. Cualquiera puede descargarse las librerías CAD o esquemas que los forman. http://blog.makeblock.cc/makeblock-robots-con-arduino-al-alcance-de-todos-analisis/








Mas para que se lembrem que às vezes, o mais simples resolve melhor, eis um Robot que funciona por simples sistemas mecânicos:


PulleyBot: A Pulley Driven Robot

The PulleyBot is a simple, single actuator 3D printed toy with a transmission entirely made up of pulley systems. This instructable is a tutorial on how to assemble the PulleyBot, but if you are interested in pulley, cable, and chain mechanisms, then I would suggest checking out this Pulley Mechanisms Instructable. I hope you have fun building this, and even more fun designing your own!The PulleyBot is a simple, single actuator 3D printed toy with a transmission entirely made up of pulley systems.

Já mandaram imprimir um Objecto vosso, e custa uma Fortuna?
Eu, já!
Pois aprendam estas dicas, simples, DEPOIS de se descobrirem, de como reduzir dramáticamente os custos, ao som de, até 70% de Poupança!
É bom!


Cheaper 3D Prints
markk7 
Have you ever uploaded a 3D design and been shocked at the high cost of production? Well I just spent the last few months getting one rude shock after another from various printing services. But I learned a few things the hard way during the process.
Getting your prints manufactured in laser-sintered nylon has a lot of advantages over printing at home. But for the first few weeks (okay, months) I was very confused. Two similar prints could vary in cost from $5 to $50. I tried making walls thinner because I thought all the costs were based on the amount of material used. Slowly I started understanding where a lot of the hidden costs were, and how to eliminate them to lower my prices
These tips are going to seem laughably simple to an experienced designer, but by using these very basic tips I reduced my average print-cost by over 70 percent since my first attempts at 3D printing through a service provider. For example, one of my very first designs dropped from $38 per print to less than $5, with no loss in quality... so I'm sharing the lessons learned.

...E se imprimir Objectos para vocês, soa a Música para os vossos Ouvidos, cá vai Orquestra, obra do MIT, nada menos de 10 Materiais, sim, 10 Materiais diferentes, usados numa só Impressão!
E imprime sobre Objectos já existentes, e resulta pouco mais caro que os tradicionais Makerbots...




MIT'S NEW 3D PRINTER CAN PRINT 10 MATERIALS SIMULTANEOUSLYKelsey D. Atherton
Right now, the typical 3D printer is a tool for making plastic objects. Assembling them in layers according to a pre-programmed plan, the printers can quickly make weirdly shaped parts, but they’re often limited to working with just one material at a time. Additive manufacturing, as 3D printing is also known, offers so much more. A new printer, created by MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), can print up to 10 materials into a single object —and incorporate other, finished parts directly into the design— all at a fraction of the cost of complex industrial 3D printers
Their new printer, known as the MultiFab, is a system of systems. A central computer runs the printing program, but as it does so it receives feedback from 3D scanners and machine vision, which map the object as it’s being made, allowing the computer to adjust the printing process and materials accordingly.
