A Impressão 3D gasta muito Filamento, por isso, cortesia da  Kas' Embedded Projects and Review, aqui vai a notícia desta máquina que produz a vossa própria mistura de Filamento:

Kas' Embedded Projects and Review
Kasriel Lewis

Possibly the biggest growing technologie today is the 3D printer, this is partly due to its decreasing cost. This drop in cost of 3D printers is largely due to the standardization of the technology as more printers use the same base technologies. The cost of filament however, whether standard or exotic, still remain relatively high.

D3D Innovations has been working to change this. Their filament fabricators allow anyone to create their own filament using various plastics, combinations and fillers. While the Filafab is meant for plastic “beads” the Filafab has had no issue working with plastic regrind from recycling plants.

THERMOFORMER / VACUUM FORMER / PATTERNMAKERDajoM  

Hi !

Let me introduce ourselves

We are a group of Industrial Design Engineering students from Belgium. For our product engineering course we had to make a tool that can embed a pattern in a sheet of PMMA. After looking for the best method we came up with a home made thermoforming machine.

In this instructable we will show how we did it.

If you have any suggestions to improve our design or you have any questions

please let us know in comments bellow

Have fun building it !

Como usar micro-switches e chaves de fim de curso como sensores (MEC097)Instituto Newton C Braga 

Este é um artigo didático de 2007 mas que se mantém atual, pois os micro-switches sempre serão utilizados em projetos de mecatrônica. Pela maneira simples como o assunto é abordado , sugerimos sua utilização como texto básico ou mesmo apostila nos cursos de tecnologia ou mesmo técnico.

Micro-switches, deep-switches, chaves de fim de curso e até mesmo push-buttons podem ser usados como eficientes sensores para projetos mecatrônicos. Mesmo a sua limitação de fornecer apenas um contacto pode ser contornada em aplicações interessantes com o uso de circuitos eletrônicos relativamente simples. Veja nesse artigo como fazer isso.

Micro-switches, deep-switches e chaves de fim de curso com uma infinidade de tamanhos e formatos podem ser encontradas com facilidade a um custo muito baixo. Na figura 1 temos exemplos dessas chaves.

Conheça a rede de montar no interior do carro. Veja o vídeo

EDIMARCIO AUGUSTO MONTEIRO 

Se você já teve que dormir em seu carro, sabe que não é o lugar mais confortável mundo. Mas, às vezes, devido às circunstâncias, é preciso, nem que seja para tirar um cochilo. Mas uma empresa norte-americana quer mudar essa situação e lançou a Car Hammock, uma #Rede removível instalada no interior do veículo em 5 minutos.

Ela é presa nas partes traseira e dianteira do carro, ficando suspensa no interior. De acordo com a fabricante, a rede suporta o peso de dois adultos, ou seja, pode ser usada por um casal. Ela somente não pode ser utilizada em veículos de duas portas ou com bagageiro no teto porque não dá para montar. Outra exceção são os veículos mais antigos que não têm os bancos dianteiros reclináveis.

Polaroid launches new 3D printers and modeling pens at CES 2017

Anthony Thurston

Polaroid, the company that many of you still associate with instant photography, has announced several new products at CES 2017 with a very different focus — 3D printing and modeling. The new 3D printers and pens are aimed at making the technology easy to use and more accessible to the general public. 

Starting off with the 3D printers, Polaroid is launching three models to choose from, varying in size but with each of the units manageable in a home or small office environment.

Uma soldadura em forma de COLA?
E capaz de fazer coisas inimagináveis, até agora, como ligar vidro e filamento...

Mesoglue - A cola metálica que pode substituir a solda

Igor Kipgen 

Uma startup nascida dentro da Northeastern University tem o objetivo um tanto quanto intrigante, por assim dizer. O professor Hanchen Huang e os seus orientados de doutorado, Stephen Stagon e Paul Elliot, pretendem colar algumas ?coisas? que para o senso comum pode parecer impossível.

Essas "coisas" são tudo, desde a unidade central de processamento de um computador e uma placa de circuito impresso, até o vidro e o filamento em uma lâmpada. O forma de anexá-los é, surpreendentemente, uma cola feita de metal que cura a temperatura ambiente e requer pouca pressão para selar. "É como soldar, mas sem o calor", diz Huang, que é professor e chefe do Departamento de Engenharia Mecânica e Industrial. O novo estudo foi publicado na revista Advanced Materials & Process. 

We bridge the gap between nanotechnology and real world applications. Meso is the space in-between.

MesoGlue was founded by Huang and two of his PhD students: They had a dream of a better way of sticking things together.
“Our first inspiration came from the desire to make dye-sensitized solar cells last longer, giving this technology the longevity necessary to become an important energy solution. We then heard reports of iPhones exploding, and realized that not only could we make devices safer, but could make them run cooler and last longer as well. We are excited to be using our expertise in nanotechnology to advance the state of technology and hopefully make the world a safer place.”

Uma espécie de escultura nova, que, quando em rotação, e sob luz Estroboscópica, aparenta mover-se, num movimento infinito e fantástico, um Zoétropo 3D, mas com a animação intrínseca ao próprio Objecto! 

Blooms: Phi-Based Strobe Animated Sculptures

edmark 

This instructable demonstrates and explains blooms, a unique type of sculpture I invented that animates when spun while lit by a strobe light (or captured by a video camera with a very fast shutter speed).

Unlike a traditional 3D zoetrope, which is essentially a flip book of multiple objects, a bloom is a single coherent sculpture whose ability to be animated is intrinsic to its geometry.

3D printing metal on a desktop FDM printer, exclusive interview with The Virtual Foundry founderMichael Petch 

Is 2017 going to be the year for 3D printing metal? Recently 3D Printing Industry reported announcements from Markforged about their forthcoming Metal X 3D printer, a drop in the price of metal additive manufacturing with the OR Laser machine and a decrease in the size of machines with InssTek’s DMT MS250.
I spoke with Brad Woods of The Virtual Foundry to find out more about his plans to bring 3D printed metal to a wider user group. 

3D printing with copper
“Suddenly every industry is starting to realize what 3D printing can do,” he tells me. Woods has developed a range of 3D printing materials called Filamet™. This material is sold in rolls and bulk pellets. It is currently available in copper, with more metals planned for release this year.
Filamet™ is a highly infused 3D printing filament and early adopters have found a range of uses for the product. The combination of FDM 3D printing and Filamet™ produces attractive and unique prints with a satisfying weight. Once printed, secondary processing using a kiln and The Virtual Foundry’s “Black Magic Powder” produces a pure metal print.
A photo sent to me illustrates the end result. “We leave the print layer lines in these so you can see the level of detail that is reproduced. It also helps with the skeptics, but I think we’re past the unbelievers by now.”

Sculpteo’s Laser Cut Metal Service is available!

Eole Recrosio  

In our quest to provide access, online, to the Factory of the Future, we decided four months ago to launch our laser cutting service in addition to the online 3D printing service. The purpose is to allow you to combine the best of the two technologies for your projects. Whether it is for 3D Printing or for laser cutting, we are constantly seeking new materials to expand our offer. We unveiled at CES 2017 our new metal 3D printing offer, with stainless steel, aluminium and titanium.

We are now launching laser cut metal! With our 3 new laser cutting materials: steel, stainless steel and aluminum.

For us, 2017 is the year of metal digital manufacturing.

Laser Cut Metal is now live!

In July 2016, we were announcing the launch of our laser cutting service in a beta program. Two months later, it was time for laser cutting to be available for all our customers, with more than 60 types of our 4 main materials: acrylic, MDF, cardboard and plywood. Since then, we’ve been expanding our offer to other materials, thickness and colors.

After our technical thermoplastic POM, we are now proud to announce the laser cut metal materials!

Metal is only the logical follow-up to widen our catalogue of over 65 laser cutting materials. With metals, we allow the completion of technical and engineering projects.

Accessible everywhere in a few clicks, you can now choose among 3 specific metals for your laser cutting projects.

Down Draft Sanding Table (On the Cheap!)*

RichFarwell 

I had a commercial down-draft sanding table when I had my own shop. It was great at keeping the dust in the shop at tolerable levels. But that table is long gone now. These days, I volunteer at our local SLO MakerSpace as the Woodshop “Guru.” We had a few “extra parts” sitting around, so I thought I’d build a new table for the Space because I really liked mine.

CES17: ARDUINO UNVEILS LORA MODULES FOR THE INTERNET OF THINGS
Brian Benchoff 

WiFi and Bluetooth were never meant to be the radios used by a billion Internet of Things hats, umbrellas, irrigation systems, or any other device that makes a worldwide network of things interesting. The best radio for IoT is something lightweight which operates in the sub-Gigahertz range, doesn’t need a lot of bandwidth, and doesn’t suck down the power like WiFi. For the last few years, a new low-power wireless communication standard has been coming on the scene, and now this protocol — LoRa — will soon be available in an Arduino form factor.

The Universal Multipurpose Workbench

Dui ni shuo de dui 

On Instructables, more than everywhere else, almost all projects will come out from some kind of workbench. However, and after quite a bit of research, I didn't find any model of workbench actually fitting my expectations. Some looked pretty nice, some other were easy to build, heavy duty, suited for wood working, mechanics or electronics, but none of them seemed to regroup all those characteristics together. This workbench was my attempt to solve this problem.

You are poor? Don't have much tools, space or woodworking experience? You are tired of sitting on the floor while you want to work on something? You are interested in every technological field and often will do electronics, woodworking, mechanic or 3D printing or milling? You want a workbench good for everything?

Then this workbench is for you!

3D Print a Programmable Musical Instrument

TINGYU QU 

This Instructable is for you to build a 3D-printed programmable musical instrument. I was inspired by the beautiful sound from a real music box so I designed, printed and assembled a 1:1 model.

This is an interesting project for us to apply mechanical engineering ideas to create a music box. I designed the model by CAD Solidworks and printed the components by UP BOX and Form 2. The mechanical motion of the device is realized by the worm-and-gear system.

In reality, I do not own a 3D Metal Printer so the "reeds" of the musical instrument do not sound very graceful. However, the project shares useful experiences about how to 3D design and fabricate a delicate musical artwork.

To build the musical instrument, the following tools and materials need to be prepared.

1. 3D Printers: UP BOX, Formlabs Form II

2. 3D Printing Materials: PLA Filament, Tough Resin, Alcohol

3. Tools: Pliers, Tweezers

In this Instructable, both the Solidworks Part Documents and the STL Files are attached.
