AEROGEL!

Impecável!

Tudo, desde a aparelhagem, até aos diversos tipos desse sólido incrível que é o Aerogel, o que não é nem rápido nem barato, mas para Universidades, e diversos Grupos de Nardos, deve dar...

How-To: Make Your Own AerogelSean Michael Ragan 

The folks at Aerogel.org are serious about it: The “Make” section of their exhaustive “open source aerogel” site will teach you how to make high-quality monolithic aerogel the way the pros do it, from building your our own supercritical drying apparatus (“manuclave” is their neologism), to mixing up the wet ingredients, to actually performing the supercritical drying operation. It still won’t be easy or cheap, but all the information you need is right there, well organized and clearly explained.

É bom!

CNC Router Rotary Axis

mkmra2

My router was a 3-axis machine. Adding a 4th rotary axis allows considerably more flexibility as the part to be machined can be rotated to expose different faces for cutting. I'd previously done some 4-axis router work at Stamps School of Art & Design - here's that post. I really wanted to add this capability to my router.

After exploring a few options - most of which were very expensive - I chose to go with an inexpensive kit from China. It was only $358 including shipping. I'd have to figure out how to get it hooked in to the electronics then build my own mount.

Eis algo de nada banal, para fazerem com as vossas Impressoras 3D...

Um Modelo de Motor Radial de 7 Cilindros!

E sem complicações de montagem, por isso, de que estão à espera?

[Project] 7-axis Hand-Cranked Radial Engine ModelMika Yeap 

Hand-cranked and fully functional, this is a model of a seven-cylinder radial engine by plusalphaDesigns. It’s a “reciprocating type internal combustion engine configuration in which the cylinders ‘radiate’ outward from a central crankcase like the spokes of a wheel,” according to Wikipedia.
It’s a relatively painless model to assemble and print, requiring just a handful of plastic parts – you don’t even need any fasteners. So let’s jump right in!

Isto existe MESMO, uma Bio-Impressora para Laboratórios, e podem fazer uma destas por uma fracção do preço das do Mercado!

Low Cost Bioprinter

mechbioprinter

The goal of this project is to develop a low-cost bioprinter to make bioprinting more accessible to research institutions. Currently, low-end bioprinters cost approximately $10,000 while high-end bioprinters cost approximately $170,000. In contrast, our printer can be built for approximately $375.

Só coisas boas!

Não é que podem transformar a vossa Impressora 3D numa Gravadora Laser?

E não é muito difícl, nem caro!

Convert a 3D PRINTER to LASER ENGRAVER | Under 40$Jakes

- To start this project we are gonna need a laser that is strong enough to burn into most of the household materials. I found that 500 mw laser is just right for this project due to its low price and capability of engraving in almost every material with exception of metals and glass.
-I bought my laser on Aliexpress for a small price. Here is the link: https://goo.gl/obFmFD
-With laser you will also get a laser driver circuit and a safety glasses which are necessarry when operating with lasers.

Build Your Own 3d Printer Filament Factory (Filament Extruder)ianmcmill

UPDATE: Now with wiring diagram !
Long read:
3D printers are cool and they finally start to drop in price. Kickstarter campaigns like the one from QB-UP or M3D are popping up and they are finally "affordable". And with affordable I mean affordable like 200 $ and not "affordable" like 2.199$ affordable. However, once you are a proud owner of a 3D printer you will soon realize that your wallet is far from being let alone. No ! You need plastic filament of course to print those super awesome coat hooks and wheel chocks. Since the price for these filaments tend to top the actual material costs, printing before mentioned life savers is kind of expensive and could become a problem to the development of the ever growing 3D printer community
BUT FEAR NO MORE !! Some clever gents came along - Hugh Lyman with his Lyman Extruder may be mentioned here or the guys over at Filastruder.com - and saved the day ! YAY. And there was much rejoicing ! They have built plastic extruders everyone can build or buy at a decent price. However if you are a fellow Instructable.com user the first thing that should come to your mind is "I can build this by myself...and cheaper...". Building at lower costs is the nature of DIY after all.
