Esferovite CNC! E aprendam Moldes, Facturar com 3D, uma Prusa SLA, e gravar a Laser com uma Prusa!

Isto é muito importante!

Já imaginaram, podem construír uma Impressora 3D, MAS, com uma armação em BARRAS MACIÇAS?

E tudo o resto que possam imaginar, porque é só verter Sucata de Alumínio derretida, para peças sacrificáveis em Esferovite/Isopor...

E já está!

A note: This, and Lost Mold Aluminum Casting, will make great solid Projects, as in, solid frame 3D Printers, for example...

4-Axis CNC Hot-wire Foam Cutter (Arduino+Ramps1.4)

rahulsrajan

A CNC Hot-wire cutter is an awesome tool to have when you are building aeroplanes out of foam. It allows the ability to cut out any aerofoil shape from a CAD design accurately. A properly configured machine can save you a lot of effort and produce a smooth finish.
The machine has a Nichrome wire stretched between two towers. The wire is heated by passing current through it and the towers move relative to each other to define the shape of the cut. The 2D CAD design to be cut out is turned into G-code and fed to the machine, which moves in four independent axes to create complex contours like tapered wings.
The motion of each axis can be achieved by any means such as linear bearings on smooth rods or by using drawer slides of various sizes. Each axis is driven by a stepper motor through a Leadscrew, a GT2 belt and pulley can also be used depending on the size of the machine. The cutting forces involved is minimal and the construction only needs to be rigid enough to withstand the tension of the wire stretched between the towers.

Nem de propósito, aprendam aqui como fazer Moldes, nem que seja para técnicas menos radicais que a Fundição! LOL

MOLD MAKING & CASTING CLASS

Paige Russell

Welcome to the infinite world of Mold Making & Casting!
In this class, you'll learn how to make easy molds that will allow you to cast multiples of virtually any object – including 3D prints – in a variety of materials, like soap, plaster, chocolate, crayon, resin, metal, and more!
In this introductory class, you’ll gain a solid understanding of fundamental techniques that will empower you to tackle almost any mold making project.
You'll learn what undercuts are and how to recognize them on your models, determine what kind of mold and mold material to use, how to build and properly seal mold walls, and how to cast in numerous materials.
It may seem daunting, but I’m a product designer and ceramicist who has been making molds for over 15 years, and I'll be with you every step of the way. I look forward to teaching you how to cast your way to a customized world!

Laser Engraving on Your Prusa MK3

marzsolt 

Yes, your 3D printer is totally capable of making awesome laser engravings. Follow along to see how I did it. Hint: it's not complicated (well, probably just a manageable amount), and I created tools to make it easy for beginners and advanced skill levels to jump in and laser away.
There are many steps and I included a lot of details. I want to be sure you understand why and how things are happening.
Disclaimer: Lasers are very dangerous, so you need to use proper care and basic common sense to not get in trouble. I warned you, I will not be responsible if you shoot down a space pirate... or lose an eye. Arrr.

Tinkerbots, perfeito para Inventores!.E Moldar por Vácuo, corte por Fio quente, mais Treatstock, imprimir 3D por perto

Isto é PERFEITO para facilitar a vida a quem quer um Protótipo em meia-hora!

Um Jogo de construcção com partes que repetem um Movimento que sintam, com Tele-controle, e compatíveis com o Lego...

Algo a ter em conta, não só para a Criançada, mas para as vossas Engenhocas. 

THIS IS TINKERBOTS 

Tinkerbots means playing and learning at the same time. Through connecting the different modules, building roobts and even controlling them, kids learn about robotics, mechanics and sensorics. You just connect the modules in a swift movement and everything works and with our brick adapters you can combine them with LEGO® bricks.

I built a larger 18x24 bed vacuum former first, and then decided that

I needed a mini vacuum former for smaller pieces and for the leftover scrap plastic from the big former. This was a weekend project and it makes great pulls.

DIY Hot Wire Cutter for Plexiglass, Cardboard and FoamRCLifeOn
This Instructable will demonstrate how you can build your own hot wire cutter, able to slice through foam, cardboard and even plexiglass!
A hot wire cutter works by a wire, often nichrome or in my case kanthal wire, which is heated via electrical resistance. As the wire reach high temperatures it slices through materials by melting it just in advance of contact.

CNC Router Parts Unveils Their New Plasma Table

Matt Stultz 

When you think of a CNC (Computer Numerically Controlled) machine, you probably think of a machine with a router attached to it, capable of cutting its way through wood, metal, and a variety of other materials.

Really, a CNC machine is a generic term for a family of fabrication devices. If you change the tool head, you can change the function and often the name. Add an extrusion head, and you have a 3D printer; a swiveling razor blade and you have a vinyl, paper, or cloth cutter; or add a plasma torch and you have a CNC plasma table capable of cutting through sheets of metal.

While we have seen numerous CNC routers and 3D printers come to market, very few DIY or kit plasma tables have found their way into Makers’ hands.

Build Classic R/C Airplanes With New Method 

whiteboardwarriors2 

This Instructable will show how to build light-weight, electric versions of a couple of classic R/C airplanes quickly and cheaply using some simple methods. Other than a very simple hot wire foam cutter, which I will show, there are no special tools required. Using these techniques and materials, it should be cheap and quick enough that you can easily experiment with your own versions of your favorites and test many different designs with varying configurations of airfoils, wing dihedral, length, etc.

The impetus for this project was Das Ugly Stik, designed and built by Phil Kraft in the 1960's as a quick to build, semi-aerobatic plane to test his radios in (Here). It turned out to be one of the best flying, most popular R/C planes ever. My goal was to be able to test various air plane designs quickly and cheaply. A good example is the photo above which shows two essentially identical airplanes except that one is shoulder-wing and one is low-wing which were built to settle the debate about which was better for dog-fighting - high wing or low wing.

É fácil "cozinhar" plástico em òleo ou àgua, a 200 e  tal Graus, e fazer Placa de Plástico...

Mas eis um Engenhocas que viu um problema, a falta de reciclagem dos Plásticos, pois ele pôs Mãos à Obra, e tratou de fazer uma linha de máquinas para reciclar plástico, e está-se a dar bem com a Iniciativa!

Um exemplo a seguir, e sobretudo, um Site a visitar, pois ele explica como vós mesmos podem fazer exemplares estas máquinas todas! 

PRECIOUS PLASTIC

Plastic can easily be recycled. It needs relative low temperatures and pressures. Look around and you’ll notice plastic waste is everywhere around us. We just need to sort it and have tools to turn it into new things.

PRECIOUS PLASTIC – THE MACHINES

This project is a set of plastic machines, developed to set up a small scale plastic workshop. The machinery is based on general industrial techniques, but designed to build yourself. The machine is easy to use and made to work with recycled plastic. Whilst this entire project is still in development, the machines are shared open source online and improved by the community.
