Um Robot Cortador de espuma, Actobotics, e 3 novos Materiais de Impressão

Este Instructable é porreiro primeiro, porque nos ensina a fazer um Cortador de espuma de rolo, e depois, porque nos apresenta este Sistema de contrucção, o Actobotics, que é incrível, e não só para Robots!

Vamos
primeiro ao Robot:




Robot Foam Cutter

jgschmidt

In the course of making stuff for myself and my customers, I frequently perform tedious tasks that could be automated. One of these is cutting foam sheets from a large roll. In the picture you see the roll of foam I start with and the desired end result, which is a stack of 12" by 71/4" pieces of foam. I've used paper cutters, rulers and razor blades, and so on and always dreaded when I ran out and had to cut more.
I've been experimenting with the Actobotics™ robot assembly system from ServoCity, and while cutting my last batch of foam realized that I should be able to make an affordable machine to do this for me. The second picture shows the result: the Robot Foam Cutter.
While you may not need a machine to do the same thing, this Instructable may give you some ideas for automating some of the tedious things you need to do.
UPDATE: I've attached a bill of materials (BOM) spreadsheet with prices in the parts section. My total cost for this project, not counting parts on hand, was about $300. Depending on your frame of reference, this may seem scary expensive or pocket change. For me time is money, and sometimes I have more money than time. For the amount of time this has saved me in the past, and will in the future, it is well worth it.








Passemos agora ao tal Sistema Actobotics, uam achado!
Imaginem um Meccano, mas com estrutura para coisas a sério, e estes furinhos todos que vos permitem atarrachar-lhe o que quizerem, e ONDE quizerem!
Só isto, por si, era muito bom!
MAS TEM MAIS!

É uma quantidade de Motores, Roldanas, Rodas Dentadas, Correias, Tubos, Kits, e mais um sem-fim de acessórios e peças, que fazem contruír um Protótipo, uma brincadeira...
...Mas com resultados de respeito!



DREAM. DESIGN. BUILD. REPEAT.

Actobotics is a ball bearing based precision building system. The unique overlapping hole patterns allow for virtually unlimited mounting possibilities, and the precision components offer structures with tight tolerances and low friction. The intuitive design makes building easy for both the experienced engineer and novice hobbyist. As you can see from the product categories shown below, the Actobotics line is vast and continues to expand at a rapid pace. We hope you enjoy working with Actobotics as much as we do!

Três de uma vez, que temos mais que fazer, cá vão Materiais novos para imprimirem em 3D, um, mais preciso, outro re-ciclado, e outro super-forte:

Mais preciso, dica da 3D Printers Online Store,um Material, que por ser mais bem-fabricado, garante Impressões sem problemas de Qualidade:


FILAMENTO - World's Next Generation 3D Printer Material
 
A new company Creadition produces a series of high quality printing materials has launched in KickStarter that will take you by surprise, especially if you have used other filaments before. I hope everyone would have come across bad prints. There are many factors that rely on the poor quality of prints mainly due to poor quality of filament, jumping, irregular extrusion, bubbles. If you have faced these problems before then you will prefer to order FIAMENTO.


Reciclado, notícia da mesma Fonte, eis algo que é produzido a partir de desperdício alimentar, sim, restos de comida!

 
Agridust - 3D printing filament from food waste

Is 3d printing a Green Technology? This is one question most people try to avoid, in fear that their answer might just start an un-ending debate. We have been pulled into many such debates and one thing that we have learned from it is that taking sides can make your best friend on of your fiercest opponent. According to us the debate supporting it or against it is completely unfair as consumer 3d printing is in its infancy. And like we all know kids learns from their mistakes, we should give 3d printing some time to mature as a fool proof solution to production of every day products.



E por fim, dica da Makezine, um super-resistente Filamento da Taulman3D, este, não dá de si tão fácilmente, e é alegadamente, tão resistente quanto o ABS:



Taulman3D Releases New, Super Strong Nylon Filament

Matt Shultz

Tom Martz of Taulman3D joined the crowds at the Midwest RepRap Fest this past weekend in Goshen, Indiana. While there, Tom took to the stage to present his company’s brand new Alloy 910, a high-strength nylon filament. Alloy 910 came about after Taulman’s corporate clients asked for a stronger nylon formulation with less flexibility than many other nylons. Tom and his team managed to formulate a new filament that has a tensile strength of 8,100 PSI, and only 25% maximum elongation (compared to ABS 5,800 PSI and 30% elongation). The Taulman team also claims that 910 has a comparable shrinkage as PLA, making it a great material for printing large rugged prints.

Dia de Instructables Impecáveis

O meu trabalho está facilitado, hoje, Instructables tão indispensáveis, para tanta gente, que, para bom Engenhocas, meia palavra basta!
Sem mais cá vão eles, que é uma limpeza...



Primeiro, não gastem mais que 30 Dólares para fazerem este bacano Scanner 3D, e começarem a digitalizar tudo o que sejam Objectos à mão.
Para que não vos falte nada, até o Software, o Sardauscan, é incluído!


Build a 30$ laser Scanner

Sardau
Introduction
This instructable will guide you to build a 3D scanner for less than $30, or even $12 if you already have a USB webcam.
Seeing the price tag and limitations of commercial scanners I decided to challenge myself to build my own. It had to be cheaper and easy for anybody to build one using a 3D printer.
Result
The "Sardauscan" is a laser scanner, comparable to other professional laser scanners but for less than 20-30 times the price, and it has twice the number of lasers.
My design principles were:
· Keep it simple
· Keep it low cost
· Make it evolutive
· Provide a complete solution
The scanner is completely open source and open hardware:
· The "Sardauscan" software is written in C# - the full source code is available.
· You can write plugins for your own hardware or for your tasks.
The software allows you to scan, smooth, build meshes and export to various formats.

Triple Threat: BoXZY Puts Printing, Milling, and Lasers in One Small Box 

Matt Schultz

On my way to the Midwest RepRap Fest, I stopped in at HackPittsburgh to meet up with the BoXZY team and take a look at their new machine in person. BoXZY is doing well on Kickstarter; with its promise of being an all in one 3D printer, milling machine, and laser etcher, it’s enticing backers. The BoXZY features a thick aluminum case that creates a stiff structure to help support its milling function. All movements are achieved with precision ball screws instead of the belts often found in 3D printers. I expressed my concern about the exposed screws getting “gummed up” from the milling operation, but the team ensured me that through their testing they have not seen any contamination in their bearings from milled material, and that they are working on a system to help ensure this.

Impressora monobloco, um Corrector de Impressões, um Mini-Torno de Madeira, e Tekever na Fox!

Eis uma Impressora 3D que aposta na simplicidade, e assim há pouco que estar constantemente a calibrar...
Para além de outros truques porreiros:


Tiko "unibody" 3D printer hits Kickstarter

Dario Borghino 

Tiko, a new budget 3D printer seeking funding through Kickstarter, takes a number of interesting design choices to minimize costs without sacrificing the quality of the print – chief among these is the use of a cheap, single-part "unibody" frame that requires very little calibration.
Ordinarily, the frame is one of the most expensive components of a 3D printer. To allow for precision printing, the multiple beams that make it up need to be machined to a high standard and then regularly aligned during their lifetime to ensure a consistent performance. This raises costs and makes it so that users often need to spend time calibrating the beams before they can start using their printers.
The Tiko gets rid of these complications with an enclosed "unibody" design that incorporates the pre-aligned beams on the inside of its frame. According to its creators, the result is a strong and lightweight chassis that is virtually impossible to misalign and that can 3D-print with accuracy (down to 50 microns) despite the lack of high-precision components.










Algumas Impressoras, algumas Impressões deixam muito a desejar, em termos de Qualidade...
Pois agora, podem corrigir isso com este Corrector de Impressões!
Alguém tinha de pensar nisto.





Retouch3D cleans up the glitches on 3D-printed items

Ben Coxworth

If you've never used a 3D printer, then you might not be aware of the fact that the objects they create don't always emerge in their final, flawless form. They often contain small printing errors, fringes of stray material, and supporting structures that need to be removed. Retouch3D uses heat to melt away those imperfections.
People already use things such as soldering irons, razor blades and sandpaper to finesse their 3D-printed creations. According to the designers of Retouch3D, however, their device allows for much more precise control.
This is partly because its heat level can be set to the melting point of the printing material in question – examples include things like PLA (polylactic acid), ABS (acrylonitrile butadiene styrene), resins or even wax. Users can look up those temperatures on the company website.










E que tal terem em vossa casa um Mini-Torno?
Este é para Madeira, e já ajuda muito, para uma data de coisas, como Modelagem, e trabalhar Plástico e até Alumínio.
Parece que com cera de Parafina, nas Ferramentas de Madeira, pode-se trabalhar Alumínio, sem arruínar as tais ferramentas...
Lembrem-se é que o Alumínio não muda de cor, quando aquece!




Mini Wood Lathe
laffinm 

Before I begin, I would like to ask you to vote for this instructable. It was made as an entry for the Tools Contest here on Instructables, and I would very much appreciate your vote. Winning contests helps me build, upgrade and stay interested in this hobby, and continue creating more content for you readers. Thank You

A little over two months ago, I found plans for this mini lathe in an issue of Shopnotes, and decided that I would try to build it in time to be entered in the Tools Contest. I had never built a wooden machine before, but seeing lots of them over on woodgears.ca, I was very excited to try one on my own. I am only 15 years old now, so my experience in woodworking is quite limited, but I still managed to complete it without too many problems along the way. Along with the lack of experience, I also do not have a large lumber supply. I built the entire lathe out of scrap plywood found in the garbage. My dad occasionally finds cut-off pieces of 3/4 inch plywood on job sites, and having a few around was enough to complete the project. (The only parts I had to purchase was a longer v-belt, and some large nuts and bolts.)

    Flexures

    © Marcel Thomas

    1 Introduction
    Flexures are bearings that allow motion by bending load elements such as beams. The arrangment of beams can be designed to be compliant in its degree(s) of freedom (DOF), but relatively stiff in its degree(s) of constraint (DOC). This allows engineers to provide motion in desired directions, but constraint in other directions. Flexures are important for engineers because they allow stiction-less, controlled, limited-range motion. These well-designed, well-understood springs can then be implemented in precision machines to allow the development of medical devices and machines for electronic fabrication. This entry is about understanding the most important parameters for flexure design. The functional requirements for flexures include (but are not limited to): desired kinematics, range of motion, stiffness, load capacity, repeatability, mode shapes/frequencies, and an error budget.
    Designing flexures involves developing a model, using FEA, and experimentally verifying the models. There should be a pencil-and-paper approximation that allows you to see which variables are most important and it gets you in the ballpark of the correct dimensions. In other words, the model shows you which direction to go and by how much. How short can I make this beam so that it can be at 30% of the yield stress? The model should answer questions like that, keeping real-world constraints in mind.
    By carefully applying these equations to your system, you should have a decent approximation for its behavior. Once the equations are developed, you should put these variables in a MATLAB script or an Excel spreadsheet. That way, you can change one variable at a time and see how that affects the entire system. Flexures are typically modeled using FEA, which is the subject of another entry.
