Shapesmith! E um Quadracóptero em Papel, soldar Alumínio sem Soldador, e marquem com um Isqueiro!


Do Grupo Impressora 3D Brasil, vem o nosso amigo Cláudio Luís Marques Sampaio dar-nos esta estupenda Dica, Shapesmith, um Programa 3D, paramétrico, e online!
Categoria!
Uma boa solução para imprimirem sem problemas.


Shapesmith 
Parametric, Open source, 3D modelling- in your browser 

Parametric
Shapesmith is parametric, so it's very quick and easy to modify your models. You can also use variables with expressions to quickly change models, like changing the radius of holes:
3D-print ready
Import STL models and edit them, and export your models to STL and print it on your 3D printer:
Browser-based
No install required - if you have a WebGL-capable browser you can use Shapesmith. Shapesmith is built with pure HTML5 and Javascript, and makes use of various new web technologies.
Open source
Shapesmith is completely open source under a permissable license (MIT). You don't have to worry about the hosted version disappearing, you can always run your own server. You can also run you own server in your school or business to keep your models private.

Eis algo de igualmente fantástico, o vosso Quadracóptero em PAPEL! 
E com as Instrucções para construírem este, vem também um Link para um Site só dedicado a construír 'Cópteros em Papercraft!
É bom! 



PaperQuad DIY Quadcopter

YoseiI 
A few months back, my friend, Kevin, came up with the brilliant idea of melding the art of papercraft with his newfound interest in quadcopters. Naturally, being an engineer myself, I quickly fell into the rabbit-hole that is the multirotor hobby and together we began developing paper frames for our small micro-scale quads.
The basic idea went something like this: After flying the factory-built quads for a while, we began to get curious about altering the configuration -- what would longer arms do? What if we flipped some motors upside down and ran them backwards? What if we made a long and narrow quad? Short and wide? We figured that folding up some paper and gluing it together would be a great way to test these different configurations quickly and cheaply.
After some tinkering, we thought that this could actually become a great activity for kids of all ages (including distinctly adult-looking ones) -- it's inexpensive, offers endless possibilities for customization, and is incredibly fun! What's more, if the quadcopter crashes and breaks, you aren't dead in the water -- just recycle the old frame, print out a new one and you're off to the races again.
This Instructable is meant to be a getting-started guide to making paper quads. Feel free to share designs, knowhow, and let's see what comes out of it! Kevin and I have started a website dedicated to this project where we will post more PaperQuad-related content: PaperQuad.com

O Alumínio é um Metal fácil de fundir, cortar e maquinar, mas um Pesadelo de soldar, ao que parece...
Mas se seguirem este Instructable, umas barritas e um bom Maçarico, resolvem-vos este problema bicudo, atenção, Malta das Impressoras, maior rigidez significa maior precisão na Impressão... 


How to "Weld" Aluminum Without a WelderDrunken Woodworker 
Using a propane torch and some aluminum brazing rods is a quick way to bonding aluminum without using a welder. It makes for a very strong bond and with a little practice can be done quickly with great looking results. 
http://www.instructables.com/id/How-to-Weld-Aluminum-Without-a-Welder/








E ficam a saber que com um Isqueiro Bic, também podem marcar, isto é, marcar a Ferro! 
Madeira, Couro, Plástico, etc, e tudo, apenas com esta Inovação bacana!



Make a Custom Bic Brander
JamesH76
In this Instructable I will show you how to 3D print your very own custom Branding Iron that snaps onto a Bic lighter!
You don't need a 3D printer, just an image, an image editing program like Pixlr and Shapeways.com to print your brand in real steel.
Disclaimer:
Yes, this is a branding iron, they get hot! Don't do anything stupid with one of these, like burn yourself or an animal! If you do, please don't blame me! :)
Second Disclaimer:
I am the designer of the branding iron, I 3D modeled the base file that your custom image gets extruded from on Shapeways, as the designer of the brand I get a bit of the profit for the sales on Shapeways ;) Don't hate me, your dollar is like a high five and makes my day more awesome :)

Juntas para corte de Placa, uma sugestão para a Impressão, façam uma Impressora Delta, e usar Material pré-maquinado

Cortesia da Make Magazine, quando cortarem Placa por CNC, tenham em atenção estas Juntas que vos podem poupar muito tempo e chatices...
Um autêntico Manual, cheio de truques, porque vem com um sem-fim de Juntas, mas, por exemplo, também as separa entre Juntas mais aproporiadas para Corte Laser, e Juntas para Fresa CNC!
É bom! 


CNC Panel Joinery Notebook 

Sean Michael Ragan 


I’ve been collecting clever ways of slotting flat stock together since I first read Nomadic Furniture back in 1999, well before the advent of the accessible hobby-class CNC tools that today make manufacturing parts like these pretty easy. Now, the world is full of people designing models, project enclosures, sculpture, furniture, and all kinds of other cool stuff to be assembled from parts made on laser cutters and CNC routers. I keep expecting a definitive book or website to emerge that covers the “bag of tricks” in an organized way, but so far, I haven’t found it. Maybe this article can serve as a jumping-off point. In any case, I think it’s time to share my notebook of CNC panel joinery. 












Para dar destaque a quem, por compartilhar ideias, como eu, lá vai avançando isto das Engenhocas, cá vai esta simpática sugestão do nosso amigo Lucas Corato, do Grupo do Facebook Impressora 3D Brasil:


 
Sistema de "contrafortes" e "arcobotantes"   
Lucas Corato  
Gostaria de compartilhar com vocês aqui um sistema de "contrafortes" e "arcobotantes" externos para ajudar a combater o warp especialmente em peças de ABS que não grudam nem com reza braba e pai de santo.
Chamo de "contraforte" e "arcobotante" pois o conceito estrutural é o mesmo que esses elementos exercem nas catedrais góticas: conduzem as forças para fora da estrutura principal. No caso das construções medievais trata-se de forças de compressão da gravidade, mas para nós são as forças de tensão resultantes da retração do ABS..
Basicamente são peças com uma base de "orelha" desconectada da peça principal, que a partir da 5ª camada aproximadamente faz uma ponte fina, com 2-4 perímetros somente, ligando-a à peça. Dessa maneira a retração sofrida por esse apoio externo é mínima e não a faz desgrudar, mesmo que a peça principal solte. E a ponte segura o bicho no lugar. 
Na última foto verão uma peça da Delta que é complicadíssima de se imprimir em ABS, solta em 99,9% dos casos, e essa eu imprimi dessa maneira, e melhor: com a mesa fria e cola de isopor (este método da cola foi desenvolvido em conjunto ao pessoal da lsita RepRapBR)..
É fácil fácil de retirar, basta um creck pro lado (vejam foto com meu dedão) ou no máximo uma passada de estilete. E, se bem feito, não deixa praticamente nenhuma marca.Na impressão da minha extrusora uso esse sistema, vejam aqui no idler, na peça principal e no carro X, por exemplo: 









Pois se queriam era construír uma dessas Impressoras 3D, modelo Delta, de maior rapidez e qualidade que as de treliça, e todas em metal, aqui vejam como o podem fazer:




Delta Bot: Perfect DIY 3D Printer

Danny Lu 
Build the efficient and reliable all metal structure 3D Printer. Improved significantly with new concepts for printers. Great quality and up to 400 mm/s print speed (very fast). Built with heated bed, hybrid bowden suspended extruder, and counterweight (tested printing 21 hours straight with no motors hot). Does not require many tools to be created. If tuned well it can last forever printing. Optional smart controller for computerless printing. Print any kind of thermoplastic.
Cost: ~$400
Build Area: 230mm (9 in) diameter, 230mm height (extend towers for higher if needed)
FDM 3D Printer:
Beginner
Intermediate (Recommended some experience with 3D Printers)
Professional
Would love to hear suggestions or improvements below.










Para rematar, cá vai um bom conselho da eMmachineShop, não re-inventem a roda, se precisam de fazer algo, usem o máximo de Material já em parte aquilo que vocẽs querem, isto é, Material pré-maquinado:



Pre-shaped Stock 
At eMachineShop, pre-shaped stock is material that comes in special forms other than sheets, plates, blocks or rods. For example, a round or square tube is considered a pre-shaped material. You might be able to reduce cost by specifying a pre-shaped material. For example, a shape that can be made by drilling holes in a hollow tube requires less machining time than starting with a block of material or rod. A part having a one inch square cross section may be more efficient to cut from one inch square bar stock. Note that specifying to use pre-shaped stock does not always reduce price.

Cheaper 3D Prints
markk7 
Have you ever uploaded a 3D design and been shocked at the high cost of production? Well I just spent the last few months getting one rude shock after another from various printing services. But I learned a few things the hard way during the process.
Getting your prints manufactured in laser-sintered nylon has a lot of advantages over printing at home. But for the first few weeks (okay, months) I was very confused. Two similar prints could vary in cost from $5 to $50. I tried making walls thinner because I thought all the costs were based on the amount of material used. Slowly I started understanding where a lot of the hidden costs were, and how to eliminate them to lower my prices
These tips are going to seem laughably simple to an experienced designer, but by using these very basic tips I reduced my average print-cost by over 70 percent since my first attempts at 3D printing through a service provider. For example, one of my very first designs dropped from $38 per print to less than $5, with no loss in quality... so I'm sharing the lessons learned.

MIT'S NEW 3D PRINTER CAN PRINT 10 MATERIALS SIMULTANEOUSLYKelsey D. Atherton
Right now, the typical 3D printer is a tool for making plastic objects. Assembling them in layers according to a pre-programmed plan, the printers can quickly make weirdly shaped parts, but they’re often limited to working with just one material at a time. Additive manufacturing, as 3D printing is also known, offers so much more. A new printer, created by MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), can print up to 10 materials into a single object —and incorporate other, finished parts directly into the design— all at a fraction of the cost of complex industrial 3D printers
Their new printer, known as the MultiFab, is a system of systems. A central computer runs the printing program, but as it does so it receives feedback from 3D scanners and machine vision, which map the object as it’s being made, allowing the computer to adjust the printing process and materials accordingly.

Basic Pulley Mechanismsprinteraction
From tank treads to bike gears to fishing lines, pulleys are used all over the place when it comes to mechanical transmissions. All types of pulley mechanisms consist of some sort of flexible belt (chain, cable, rope, etc.) turning around the circumference of a wheel, and pulleys can be incredibly useful in a variety of situations. In this Instructable I'll go over some basic pulley concepts and interesting mechanisms, and hopefully you'll be able to design your own pulley systems and make stuff like this!

..E para terminar em beleza, por hoje, que tal uma Fresa CNC por 20 Dólares?
Cá vai ela:


$20 CNC MachineTchbuilder
I got inspired for this instructable when I viewed the Easy To Build Stepper Controller
instructable .When I read the instructable I knew I could make a decent looking and functioning cnc machine for under 20 dollars with a recycled twist, Not to mention I did this in under a week.
I expect you to have basic knowledge on power tools and hand tools
and of course this instructable requires you to have a rotary tool such as a dremel.
Even if you don't have knowledge on power tools or hand tools I advise you to try this instructable because you will learn a lot about hand and power tools and you can build this for less then 20 dollars
so if you mess up it's no biggie and it would not cost to much to replace a part.
Let's Build!

Como há tanto Acidente por aí, por se usarem métodos artesanais, com o Fogo-de-Artifício, cá vai esta ideia para modenizarem a coisa, sem percalços:




Firework Control Module

JonBush

A few years ago I came across a firework control module built by Instructables user: systemf92. His module was a great design (found here) and I knew that I would one day have to build something similar because it combined two things that I really enjoy: Electronics and Blowing Stuff Up on Independence Day. Well, a few years passed and I finally decided it was time to build one of my own.
My module is Arduino powered for a few reasons. 1) I need to work on my programming skills. 2) I wanted it to be "smart" or "aware" of what connections were present. 3) I wanted to have control over timing adjustments that a more analog solution wouldn't allow. 4) I wanted a more graphical user interface that would be fun for my kids. The complete solution was a two part module that allows you, children, babies, etc to safely enjoy launching fireworks from a minimum distance of 50 feet. I wouldn't have felt comfortable sending my 3 year old up to a mortar tube with a punk, but I would let him launch them all day with this and its included safety features.
