Façam a vossa Impressora 3D! E magia LED, Acabamento 3D, Peltier para Câmaras, e Craftware

Se têm acesso a uma Impressora 3D, dalguma Fablab, ou de alguém que conheçam, podem, em troca dumas Bobinas de Filamento extra, e mais uns Trocados à parte, ter esta bestial Base CNC, que pode ser uma Impressora 3D, uma Fresa CNC, uma Cortadora Laser...~

Ou as três, com 3 cabeças de encaixar!

É bom!

Cheap Scalable Arduino CNC (Plotter, Mill, 3D Printer...)

mendelecha1 

In this Instructable I'll show you how to make a cheap scalable CNC machine controlled by Arduino. My printer has a usable volume of 1500x1000x200mm. It will provide a computer controlled plate where you can add any kind of tool for your application: laser, mill, drilling machine, 3D printer head, pencil…

THIS IS MY FIRST INSTRUCTABLE, PLEASE VOTE IT IN THE First Time Author Contest!!!

In order to maximize customization capabilities and reduce costs:

Most parts are 3D printed

Open source hardware / software

Tube profiles work as Rails

If you are looking for a CNC but don’t want a single purpose thousand-dollar machine, this is your project!!

Be sure to watch the video above, and if you like it please consider subscribing to my channel which has been recently created and will be updated with new amazing projects.

Before starting you should know the usable length, width and height you want for your machine. The less heigth (Z) the better.

This project is based on Allted's design CC BY-NC 3.0

Algo fácil de fazer, mas espectacular, é este Globo LED que podem fazer, e ter a satisfação de criar, sem dar cabo da cabeça...

Claro, isto vai-vos convencer a mererem-se em mais Projectos, mas há Vícios bem piores! LOL

Make Your Own POV LED Globe

GreatScottLab 

In this project I will show you how I combined a couple steel pieces with an Arduino, an APA102 LED Strip and a Hall effect sensor in order to create a POV (persistence of vision) RGB LED Globe. WIth it you can create all kinds of spherical pictures or even letters which is a definite eyecatcher. Let's get started!

Uma Impressão 3D para uma Prova-de-Conceito, não precisa de ter um acabamento especial, mas há alturas em que o Aspecto vende uma ideia.

Para isso, ou seja lá para o que for, Montras, festas, Modelos para Arquitectura, etc. vejam bem aqui, como obter um Visual de fazer chorar as Pedras da Calçada...

Guide: How to Finish 3D Prints

brett 

While I have 3D printed hundreds of designs over the years, not once have I taken the steps to finish a single print. There are plenty of videos and articles covering the process but they are often a general overview and leave out small but important bits of information. For someone inexperienced like myself who prefers to follow explicit instructions, the artistic process can be a rather daunting task. Unfortunately I purchased my 3D Printers for costume and prop design and can’t leave them unfinished forever, where this guide will cover my successful, albeit awkward adventure into the task of post processing 3D prints.

Não sei se não se poderá usar isto para cabeças de extrusão das Impressoras, ou mesmo para os Computadores sobrecarregados dos Engenhocas, mas já para estas Câmaras espectaculares, é uma Maravilha...

A Impressão 3D depende em tudo duma boa traducção dos nossos belos sonhos em 3D, em GCode que produza algo de jeito.

Sem isto, é só Filamento estragado, acreditem que sei do que estou a falar...

Por isso, estes Programas Grátis, que encontram na Net, são tão importantes!

CraftWare

Overview 

CraftWare is a FREE, fast, easy-to-use slicer software that converts your digital 3D object into a .gcode toolpath format understood by most 3D printers.

CraftWare primarily works as a slicer for solid 3D digital objects, but it is also an excellent tool for many other tasks. You can interactively manage your prints, thus reducing build time and finding the optimal build supports. CraftWare also utilizes the most impressive gcode visualizer on the market; this allows you to see each print layer-by-layer, from any angle, easily allowing you to detect any places that you may want to modify before printing. It is basically like seeing a finished print in front of you before you press the start button.

CraftWare utilizes dual channel communication for real time interaction between the software and the printer -just another great tweaking option.
