E uma dica de 陈英, na paǵina Facebook, 3D Printers PT, estes bacanos estiveram com o seu Projecto no Kickstarter, e conseguiram passar a ser uma Empresa...
Porque são bons!
Uma Impressora DLP, que imprime Objectos com uma Resolução e rapidez incrível, e por menos de 1000 Dólares, é simplesmente fantástico, e eles até estão à procura de representantes, por isso, vão lá:


New Uncia DLP 3D printer


We have engineers, designers, and leaders in our 3D Printing Department of QSQM Technology Corporation. In 2012, QSQM corporation launched 3DP department, a department focused on developing high-end desktop 3D printers.
We reinvented the light-curing machine with our passions and our visions. We are presenting you the best desktop 3D printer with high resolution and low cost !
QSQM  invented the first layer-by-layer forming rapid prototyping machine in China-the high resolution 3D printer based on DLP technology, and improved the normal UV resin formula to visible-light curable formula. It’s the only company obtains the visible light-curing equipment and supplies of patent in China. We provide you with a professional 3D molding technology and customized manufacturing integrated solutions.

Our DLP technology is based on TI’s Digital Light Processing DLP technology, and implemented by professor Mr. Pineaul. QS series 3D printers based on DLP technology can greatly improve the speed of 3D printing and rapid prototyping, and reduce the time and cost of production and design.
Eis uma Dica da Make Magazine, para quem já tem um outro tipo de  Impressora 3D, as de filamento, um Vídeos sobre como conseguir que aquelas primeiras camadas de Material impresso saiam perfeitas, para uma boa Impressão:

First Layer Problems: Quick Tips For 3D Printing Beginners
Caleb Kraft

Doodaddoes is back with another very clear and helpful video for 3D printing beginners. This time he’s exploring some very common problems with the first layer of a print. If anyone has been printing for a while, they can tell you that the first layer is extremely important and that they probably spent a lot of time figuring out the tips in this video. I know I would have appreciated this when I was just starting out.

If you’re just starting out, you may notice that his printer is the Delta configuration, which has 3 dangling arms. That makes no difference on the lessons he’s teaching. These tips will apply to you no matter which type of filament based printer you use.

E a HP, das Impressoras de escritório Papel A4, está a planear arrasar a Concorrência, com esta Impressora 3D, que promete, por também ser de Jacto-de-Tinta, para Imprimir 3D...

HP's 3D Print Breakthrough Could Push Rivals 'Out of Business'
George Anders

After years of tinkering in the labs, Hewlett-Packard finally is making a big bet on 3D printing. Although HP is targeting a crowded market, the company’s inkjet technology — announced today — looks so revolutionary to analyst Terry Wohlers that he predicts “it could even put some other companies out of business.”
Factory bosses around the world are intrigued by the potential for 3D printing, which rapidly fuses together layer after layer of plastics or other materials, until a full-fledged object is created. In recent years, pioneers such as Stratasys and 3D Systems have transformed this technique from a science-fair curiosity into a mainstream manufacturing technique. In the auto and aviation industries, 3D printing (also known as additive manufacturing) helps prototype all kinds of parts. In dentistry and jewelry, 3D printing is part of everyday production, especially for intricate, customized items.
By choosing inkjet technology, HP is sticking with methods that have helped it make billions over the years, as the dominant player in conventional, two-dimensional printing on paper. HP officials earlier this month showed FORBES some massive inkjet print heads that have been configured by engineers in Barcelona, Spain, to handle finely powdered versions of the nylon plastics frequently used for 3D projects. Video footage of the print heads in action is here.
