Novo Método de Impressão 3D! E Woodworking Tips, um Arduino feito em casa, e ainda mais uma Impressora 3D feita por vós

Dica da 3D Printers Online Store:
Por ser baseado num Gel que endurece com Ultra-violetas, exibe a facilidade de impressão da Impressão de Filamento, e a resolução incrível da DLP, e ainda, com um Volume enorme, e uma rapidez fantástica, parece-me que ISTO é mesmo o Futuro do Fabbing:



MASSIVit 3D: GDP Gel Dispensing 3D Printing technology  
When we think about 3d printing more often than not we are thinking about a small desktop printer, but not everything can be printed on these small printers. If we have to print larger models we have to slice it into smaller parts so that it can fit the build base of the printer. This is actually a crude stop gap solution to a problem at hand, but FDM 3d printing being extremely slow and the inability to control failed prints makes printing large objects a real task at hand. The Biggest 3d printer that we know of is the BigRep ONE.2 which has a 1M³ working volume, but it still inherits the shortcomings of the FDM printing technologies we discussed earlier. So is there a solution at sight? There certainly is and it’s coming from the promised lands of Israel. - See more at: 







Ora vejam lá... Se isto não é uma solução bacana também para o Laser Cut!
Pois é, pode-se aprender MUITO com estas Dicas de Carpintaria, da Woodworking Tips, que serve também para o Fabbing, e Engenhocas em geral: 




 Wedged Mortise & Tenon
 
Tap, tap, tap. The wedges go home, the glue squeezes out and a big smile lights up your face. “This joint isn’t coming apart for a hundred years,” you say. “It’s as solid as a rock!”
 






E se têem pouco dinheiro disponível, mas precisam dum Arduino, porque não, fazerem o vosso próprio Arduino, em casa?
É o que podem fazer com este Instructable: 



Beeduino : Homemade Arduino on a Budget 
bjkayani
 
Hey what the cost of this blue board thingy, "Arduino" i think its called?? Well the cost is about $30 per board. Woah $30 for just this simple circuit. Whats so special in it? Well nothing actually. Its just a simple open source development platform with awesome I/O and programming potentials. Open source eh? Doesn't that mean we can make our own possibly much cheaper? Well i think so....
These were my thoughts when i got into the world of ARDUINO. After having bought many original and chinese arduinos i have finally decided that its time for me to make my own arduino. Now i wouldn't recommend people starting arduino to make this but people who have worked with arduino even a little should try this. 
 




 




Como não quero que vos falte nada, aqui vai, ainda mais outra Impressora 3D para fazerem nas vossas Garagens, Oficinas, ou Cantinhos das Ferramentas... 




A low cost 3D printer with basic tools

Introducing the 'Ad(str)apto'
Welcome to our 1st attempt at doing an instructable. This is a cheap, quick and very 'hackable' bootstrap printer loosely based on the reprap 'Adapto' (http://reprap.org/wiki/Adapto) The print volume of this printer is approximately 8 litres (200x200x200mm), but could easily be adapted to print a bigger volume.

Fresa CNC de 5 eixos, por 3.300 Dólares! E uma Impressora 3D por 299, um Aspirador impresso em 3D, e um Retrato dum Inventor!

Isto é incrível, podem agora fazer objectos complexos em Cera, Madeira, Plásticos E Alumínio!
É uma máquina topo-de-mesa, mas não se esqueçam de que podem fazer peças grandes em segmentos, e desenhar as Engenhocas de forma a usar Tubos e Chapas nas partes menos complexas...
Impecável! 



Pocket NC - The first 5 axis CNC mill for your desktop.

Pocket NC 

What is the Pocket NC?
The Pocket NC is a 5 axis desktop CNC mill. 
Now let’s break down exactly what that means: 
Milling Machine: Today, most people are familiar with the concept of 3D printing which is an additive manufacturing process. The part is built up from the base by adding a layer of material at a time. Milling is a subtractive process where material is removed from a solid piece of stock using a sharp tool to reveal the part inside. 
CNC: CNC stands for Computer Numerical Control. This means that the machine is controlled by a series of codes and numbers output by a computer. These codes can either be output by software, or written line-by-line in a text file. For more information on the software you need, keep reading. 
5 Axis: If you are having a hard time visualizing what “5 axis” could mean, don’t worry. It’s a lot more simple than it sounds. Conventional milling machines typically can move in 3 linear axes at a time. An example of this would be a milling machine where the part fixed to the table can move back and forth in two directions (X and Y axes) and the cutting tool can move up and down (Z axis). The extra 2 axes of movement are rotational, which for the Pocket NC means that the part can also rotate about the X axis (A axis) and about the Y axis (B axis). The main advantage of this is that you can now machine on multiple faces of the part without having to refixture it.

New High Quality Portable Afinibot Creality 3D Printer Launches for Just $299

WHITNEY HIPOLITE 

The majority of 3D printers are large, clunky, and somewhat fragile machines. The idea of moving them back and forth between rooms, or in and out of a closet just isn’t very feasible. We have seen several “portable” 3D printers come to market over the past couple years, but most are expensive or simply don’t do what they say. This may be about to change though, with the new Afinibot Creality 3D printer now available at 3D Printers Online Store.
The new 3D printer kit features a decent size build volume of 130 x 150 x 100 mm and can print with a layer resolution of 100 microns. It is built with a sturdy aluminum and acrylic frame, and weighs just 4.9 kg (approximately 10.8 pounds). Best of all, it’s priced at just $299 with even larger discounts available for higher quantity purchases.









Como o lixo se acumula à volta do PC duma forma assustadora, eis uma simpática ideia para usarem as vossas Impressoras 3D, que vai agradar à Patroa, um Aspirador que funciona alimentyado por uma saída USB do mesmo Computador:

Uma Impressora DLP por 60 dólares! Outra por menos de 500, mais Crowdfunding em Português, e

As Impressoras DLP são as que resultam numa Impressão mais fiel ao modelo, nada das "escadinhas" das Impressoras FDM, de Exrtusor e Filamento, e agora, podem construír uma, com 60 Dólares, o que é fantástico!
Com umas tralhas que praí tenham, um Projector Vídeo em 2ª mão, e um DVD velho, mais isto e aquilo, vão poder fazer esta pequena Maravilha: 




Chimera: $60 DLP High-Res 3D Printer

matstermind

I have been on a hunt for the past several years to find a cheap and simple, yet moderately high resolution 3D printer. I had 3 different 3D printers partially constructed when I heard about the amazing technology of DLP Stereo lithography (SLA) printers. I have finally found enough parts at the right price to construct a fully functional printer capable of amazing quality with spending less than $100. Top down DLP printers in their simplest form have only one axis of motion, a video projector, and minimal electronics. They do not require a heated or perfectly level bed, there is never a clogged or wrong temperature in the extruder as it does not use an extruder. And the resin used has a comparable price to FDM printers.
The chimera (ky-meer-a) is a mythological creature that is made up of 3 different animals, this printer is made using the recycled/modified parts of 3 different categories (projector, toys, and old computer stuff), hence the name.
I am always looking for constructive criticism, let me know if you think i can improve on the project, or the instructable! 
http://www.instructables.com/id/Chimera-60-DLP-resin-3d-printer/








E se quizerem uma Impressora capaz de imprimir objectos maiores, têem esta, que fica um pouco mais cara, mas faz com que a diferença valha a pena!
E, francamente, é bem mais sólida.





"Little Dipper" SLA/DLP 3D printer for under $500 (projector included)

marshallpeck


A brief overview:
This Instructable is about building a simple yet versatile resin (SLA) 3D printer that uses a cheap DLP projector to build the part from the "top down". This orientation of the light source is similar to other large scale industrial SLA machines. It has some advantages in simplicity, scalability and disadvantages in minimum feature size and print time.
This version build is budget conscious, has a low part count, can easily be upgraded and scaled in size. The entire 3D printer (projector and resin included) can be built for just about $500 or less which makes it one of the cheapest bang-for-your-buck 3D printers using SLA resin out there.
There are many good Instructables and resources that contain more exhausting detail about DLP resin 3D printers and background information. If you are interested in learning more about this http://www.buildyourownsla.com/forum/ will be one of your best community resources for knowledge relating to the topic.

Freaks3D, uma Oficina no Quintal, como encontrar o Centro, Bricolage, e Bitmovel

Dica do nosso amigo Eddy de Ridder, cá está mis uma Impressora 3d, esta mais portyátil, fácil de operar, e barata...





[Pre-Order] Freaks3D - a reliable and affordable 3D printer. Take It Everywhere !

FREAKS3D PRINTER
As makers, we love 3D printing.3D printing makes our lives easier. We use it to print mechanical parts, tools, prototype our product, verify our assumptions or just make gadgets we love. It’s easy, fast and low cost.
We are amazed by 3D printing technology. However, the 3D printers on the market are far from satisfying. Most of them are bulky, not light-weight enough to be carried around, hassles to use, plus price ridiculously high. We want a reliable, affordable and portable 3D printer that we can take everywhere. Moreimportantly, it should be easy-to-use for general consumer crowds like artists/designers, educators, household wives, even children who are curious about creation.

2 Car All-Metal Workshop For 2 Grand

gizmologist

Overture: A Tale of Two Cards...
It began as a blueprint on an index card...
It began with a Lowe's credit card...
Based on a True Story,
Building Steel!
You say you'd love to have a two car garage, but you can't afford it? Or you need a workshop to build your dream airplane/car/boat/World Domination project? Here's a 400 square foot (20 X 20) all-metal shop for a little over two thousand dollars (A slap in the face to the bank!), built entirely from common parts available at any home improvement center.
This shop fits our budget because it's built without using a concrete $lab, expensive framing or siding. It's based on the old Quonset Hut design dating to World war II, although the construction method is different. The original Quonset Hut was a 20 by 48 foot hemicylinder (half cylinder); this one is slightly less than half the size of the original. Anybody that knows anything about structural design will tell you the dome is the strongest shape possible for a building - Buckminster Fuller made geodesic domes a household word. But domes are hard to build, and don't make the best use of floor space. The Quonset Hut is a "dome" in one dimension, while still maintaining a rectangular floor plan. It's much easier to build, because there is no need for tricky angles (as a geodesic dome requires) or compound curves, and it's still very sturdy.

Máquina-Maravilha! E façam uma Lixadora de Cinta, Ebooks sobre 3D, mais um Misturador acessível.

Rida Banaki partilhou um Vídeo que figura em Hergunyeni.com, e ficamos agradecidos a ambos, porque esta Engenhoca é FENOMENAL! 
Não será preciso enunciar as vantagens duma multi-mãquina que se leva numa mão, para todo o Engenhoca com pouco espaço ou pouco tempo, ou para o Modelista que leva tudo para onde possa testar os Modelos, e ainda menos para os Inventores, que tẽem de expôr as suas Invenções em Exposições onde falta sempre alguma coisa por fazer, ou precisam de consertar algo à última hora...
Boa ideia! 





POWER8® Workstarion
The world´s first cordless workstation. Ideal for professional tradesmen and DIY enthusiasts, the set includes a stainless steel armoured case which when combined with the four 18-volt cordless tools transforms them into their powerful benchtop equivalents..







Uma Lixadora de Cinta que fazem em casa, é o que podem fazer, se seguirem as ideias bastante fáceis de implementar expostas neste Vídeo de Marcos del Aguila, que tem o detalhe de poderem lixar à volta duma roda, ou a direiro, e muitas outros detalhes a notar:

Vai ser preciso, um dia, melhorar o acabamento das vossas Impressões 3D, ou então,  pulverizar ou misturar algo, por exemplo, Bentonite, para Fundição em Areia, ou Ferrugem e Alumínio para Thermite, (MUAÁHÁHÁ, grandes pedaços de Sucata convenientemente cortados, e em segundos!).
Para isso, não gastam quase nada, se seguirem este simpático Instructable: 



  
Affordable Rock Tumbler
onkelgeorg 
 
This is my affordable rock tumbler designed to tumble 3D printed parts, printed with ColorFabbs metal filled filaments (BronzeFill, BrassFill, CopperFill). It is also possible to add a 'golden' shine to regular PLA when the parts are tumbled with brass screws. It should be possible to build this tumbler for less than € 40.- which makes it much more affordable than 'professional' tumblers that can do nothing better than this one ;-)
With the 110mm drum it turns with approx. 22rpm - feel free to adjust the speed with different gear wheels (see note below).
You can go with a drum of your choice (i.e. old tins, etc.) but I found that PVC pipe couplings that are sold in hardware stores are perfect and cheap. This tumbler is designed to run with either diameter of coupling like 110mm, 125mm or 160mm (latter not tested yet). The 110mm drum is large enough for most of my parts and should be the starting point for your first try. For those who like a rubberized drum it is a good idea to print the inset for the drum with flexible filament.

How to Make Your own Plasma Cutter....Plasanator 
Check out new video of the Plasanator on utube.com
This Ebook is designed for Guys and Gals who like to create tools and machinery.
I hope my Ebook gives you hope that no matter how hard a project may seem, keep plugging away until you finish and you will succeed.
I spent 3 years putting this together and now finally all my hard work and research has paid off.
I studied diagrams from commercial venders, but to no luck. They tend to leave a lot out – on purpose - so it’s hard to reproduce their design. I’ve see different attempts at people making their own on You Tube and other sites, but what a death trap. Messy water resistors and wiring like a darn Christmas tree.
So I began reading books and articles on their workings and took my home schooled-knowledge of electronics to build my own plasma cutter. I was determined; failure was not an option.
I started by collecting parts from old microwaves, stoves, water heaters, air conditioners, car parts and more in the hopes of creating a low budget way to create a plasma cutter for myself. I mounted it all on a simple piece of scrap wood; well it’s scrap wood now. We, didn’t need that table anyway (shhhhhhh don’t tell the wife).
Then one day it all came together. I hit the power switch, placed the head to the metal, started the arc, felt the air kick and then a second hard kick (the current being drawn into play). Then BAM, it was slicing through quarter inch steel like a hot knife through butter.












Podem apenas precisar de fazer Placas ou Blocos em Plástico Reciclado, para terem à mão quando precisarem, ou maquinarem como quizerem... 
Aqui está como fazerem Plástico à fartazana, sem mais, neste exemplo, um Bloco de todo o tamanho foi ao Torno, e já lá canta uma Terrina: 





Milk top bowl
matt.sims.37266
 
Hi
This insturctable will go through how I turn milk bottle tops (and various odd ones) into blanks for working with, mainly for turning but you can work it just like timber so your imagination is your limit :)
To start off with you need LOTS, just to be clear here LOTS of milk bottle/coke/fabricsoftner tops I get various places like cafes, staff canteens an family to save them for me just ask whoever you can.
A mold, this should be near the shape/size you want to use less caps, in my case im making a bowl so i used a bowl. If you want to be safe have one that you can melt into at 200 celsius because trying to melt it and move molds is unplesnt the lids retain loads of heat and stick to most surfaces so its just asking to cause serious burns.
An oven to melt it in. an expensive bit of kit but if you look hard in the kitchen (the place you take the lawnmower apart when it breaks before you manly shave the lawn) you might be as suprised as me that you already have one. (same applies to the mold the next cake my wife bakes will have plastic in it...)
And a work shop or tools to create! in this case a lathe was all i needed
