Alibre é agora Geomagic, limpar os vossos Vectoriais, imprimir 3D em translúcido, e imprimir 3D com Mindstorms!

Alibre design mudou de nome, para Geomagic(?)

Eles lá sabem, e eis mais informação acerca disso:

Alibre é agora o Geomagic Design - CAD 3D Paramétrico

Temos o prazer de anunciar a nova versão 2013 do Alibre Design com imensas novas ferramentas e funcionalidades. Mas em complemento às novas funções da melhor versão de sempre, há uma mudança significativa que irá reparar – O que era Alibre Design agora é Geomagic® Design.


Veja os que há de novo nas funcionalidades da nova versão, Geomagic Design 2013:

Para que os vossos Desenhos Vectoriais em formato SVG, da Inkscape, sejam legíveis e se carreguem para Sites como a Ponoko, sem problema, experimentem este Programa bacano, pela minha experiência pessoal, transformou um Ficheiro SVG de 900 Kbites, cheio de problemas, num de 500 Kbites, que carregou num instante:

Introducing SVG Cleaner 

If you do a lot of drawing in Inkscape, you know that unused elements tend to accumulate and blow up size of SVG documents. This is where recently released SVG Cleaner 0.2 comes to rescue.

Basically the application does two things:

• removing elements and attributes that don't contribute to the final rendering;
• making those elements and attributes that are actually used more compact.

While Inkscape's Vacuum Defs command only cleans up unused gradients and suchlike, and Scour-based exporter provides some additional options, SVG Cleaner provides far, far more options and works in batch mode.

Besides, you still need cleaning up files from Adobe Illustrator and Corel DRAW (Inkscape can do it for the former, btw).

Caso queiram fazer algum Projecto com Luz e Som, como as Colunas que vos mostrei ontem, eis um novo Material para imprimirem em 3D, translúcido, à vossa disposição pela SeeMeCNC:

Sold in 1# spools as shown
The NEW Taulman 645 Nylon Filament is now here!!!
Taulman 645 prints similar to the 618 Nylon. It prints at slightly above ABS temperatures, and has the same warping tendencies as 618 nylon, but with an increase in the structural strength, as well as imporved clarity and and bridging performance for complex prints

Features of taulman 645 3D Printing material

Very High Strength - Expected Tensile Strength, Yield = 16,533 psi
Extreme Durability - Expected Elongation at Break =120 %
Excellent Bridging performance
Advanced Chemical Resistance
1:1 nozzle dia to layer height capability at design strength
Superior Surface Texture
Color by dyes
Visual Non destructive evaluation - Designed to be clear and optically correct

E ainda na Impressão 3D, desta vez, imprimir em 3D, com Pistola de Cola, atenção, de barras coloridas, e que brilha no escuro, e com um exemplar devidamente programado da Lego Mindstorms!!!

DIY Glow 3D Printer

searx

If you  read my interests, you probably know that I love studying the 3D printer we have at school to see how it works. If anyone wants to know more about 3d printing, there is a really cool article here. Anyway,  I spent about a month (as an engineering student I know how important research is) sketching designs and building prototypes. After that I finally found a design that fit my needs. This printer is based on the brain of a mindstorm NXT because it is easy to program and my arduino chip is burnt out and I'm still trying to save up to buy a new one. This printer only prints as accurately as you program it, but I will show you the best method of programming. The design includes x-axis and  y-axis movement as well as z-axis movement used to pump down the printing material.
Time to make: about 4 hours if you have all of the pieces in front of you
