3D SOBRE 3D! E Sintratech, não de Sintra, mas da Suiça

Eis algo que vai ser de uma enorme utilidade para quase tudo, porque se vai um dia imprimir em 3D, SOBRE um objecto, não uma placa, mas um objecto qualquer que caiba na impressora!
Por conjugar uma Impressora com um Scanner, a Impressorasabe sempre onde, e como, a superfície de impressão está.

Haverá melhor maneira de reparar tanta coisa, e de fabricar peças de artefactos muito mais complexos do que os de hoje?

Havia a Foto-Montagem, isto será a 3D-Montagem! 
E como aponta aqui Cabe Atwell, da Make Magazine, poder-se-há RETOMAR uma Impressão 3D, parada a meio!

3D Printer That Scans Objects to Print on Its Surface

Cabe Atwell

When it comes to unusual 3D printers and materials, MIT takes the proverbial cake. Students and researchers from the prestigious institution have designed printers that can print food (The Cornucopia and the latest machine to print ice cream), robots (Origami Robot), and even composite bones (CPU optimized designs of soft and stiff polymers).
Now researchers have designed a prototype 3D printer that is capable of locating and printing on objects that are positioned on its printing tray. Trying to print on an object usually involves ‘eyeballing’ the location or using specialized camera equipment to get the precise location. MIT’s solution was to combine the printer with a 3D scanner, making the job a heck of a lot easier to do, especially on irregular surfaces. Not only that, but it works for previously stopped printing projects that would otherwise become useless preformed objects destined for the trash.

Esta é uma Impressora 3D com um nome curioso, Sintratech, não é de Sintra, mas de Sintering, e são da Suíça.

De qualquer maneira, cá vai o Artigo, também da Make Magazine, onde podem ver, no vídeo, porque estas Impressoras 3D, de método SLS, valem a diferença de preço, são mais rápidas, executam peças impossíveis nas mais baratas, as de deposição de plástico fundido, e em plástico que permite criar peças muito mais resistentes!

Sintratec: Affordable Home SLS Printer Coming Soon

Caleb Kraft

Desktop Selective Laser Sintering, or SLS, is a highly sought after item in the 3d printing world. SLS printers print by layering fine powder, then selectively “sintering” or melting it with a laser. Since there is a solid “cake” of powder, no support materials are necessary. Typically these machines are extremely expensive and quite large. Sintratec is hoping to change that.

The Sintratec team currently consists of 3 electrical engineers based out of Switzerland: Joscha Zeltner, Christian Von Burg, and Dominik Solenicki. The three hope to launch a crowdfunding campaign in October to raise enough money to ship at least 60 kit printers. Their current target price is under 3999€ ($5,277), which is considerably cheap for an SLS machine, though still quite pricey compared to your typical FDM printer. However, as you can see in the video above, they are quite different machines.
