Impressora Invulgar! E a Verbatim vende Filamentos, e o Gerador Whimhsurst

Isto é FENOMENAL! 
Trata-se da mais genial Impressora 3D que eu vi, porque pode ser construída por qualquer um que vá a uma Sucateira, e arranje uma Impressora Multi-Funções, mais umas peças...
Já não há desculpa para não imprimirem em 3D!




Plan B, an open source 3DP (powder and inkjet) 3D printer

dragonator 
Plan B is an open source 3DP 3D printer. It uses binder and powder to create it´s parts. It can be built for €1000,- ($1300,-) if the parts are sourced right. It uses standard 3D printer parts and electronics, off the shelf inkjet components, 3D printed parts and a sturdy laser cut (or water cut) aluminium frame.

It has a step accuracy of up to 0.05mm and has a printing accuracy of 96DPI (coming from it's HP C6602 inkjet cartridge). The inkjet technology on Plan B is based on the inkshield. It has a printing envelope of 150mmx150mmx100mm and has a layer thickness of 0.15mm to 0.2mm. It's current speed is 60mm/s, though with better firmware this speed can easily be doubled.

It currently prints in special 3DP printing gypsum with matched binder. Additional materials are going to be investigated.






Dica de Tozé Soares, no Blogue da 3D Printers PT, eis a prova de que a Impressão 3D ganha força no Mercado, até a Verbatim, a Marca que vende CDs e DVDs, já vende Bobinas de Filamento!

Verbatim Enters the 3D Printing Market with its New Filaments
The Engineer
Data storage giant Verbatim is using IFA Berlin running from September 5-10, 2014 to announce its entry into the fast developing 3D printing market with the availability of a top-grade range of PLA and ABS plastic filament materials.
The 3D printing process enables physical objects to be made from three-dimensional models by laying down successive layers of a material in an additive manufacturing process. The 3D printing industry is currently undergoing a massive transformation and enjoying unprecedented growth that is estimated to reach a value of $669 million (€500 million) in 2014, according to Gartner. Now, new and more technologically advanced 3D printers are increasingly being introduced that target use in homes, schools and universities, and key business and industrial applications.
 









E para rematar, um pequeno Gerador Whimhsurst, que podem fazer com Cartolina e CDs, e produzir as sempre tão satisfatórias, FAÍSCAS!
Muháháháhá!


Small Wimshurst generator from cardboard and CDs
Sparticles

The Wimshurst influence machine was a popular machine at the end of the 19th century to generate high voltages.
From it's development ~1883 it superseded other devices such as the "Holtz" and "Voss" machines. It was one of the first ways to generate high voltage to more or less conveniently take Röntgen pictures around the turn of the century. For example, this 1909 book on radiography: Radiography and the "X" rays in practice and theory with constructional and manipulatory details by S.R. Bottone has an interesting chapter on Wimshurst machines, how to hook them up to a Crookes tube and how to take X-ray pictures. My little Wimshurst machine should in theory be able to do the job, but it will take a very long time to get 10 good flashes. And the tiny crank is not ergonomic. And I don't have a Crookes tube.
