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)rahulsrajanA 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 CLASSPaige RussellWelcome 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!
...Uns bons duns conselhos que eu devia ter ouvido antes, é o que este Bacano, Angus, da Maker's Muse vos dá, e aprendam, que podem assim fazer uns cobres com a vossa Impressora 3D...
3D Print on Demand for Profit (Without 3DHubs!)
In this video I'll share my experiences in running a successful, profitable business around 3D Printing on demand, without using 3DHubs and similar style websites. NOTE! This video contains my opinion and experiences on this subject and is not legal or business advice. You are responsible for your own business decisions!

O grande Prusa, mais a sua Equipe, oferecem-nos esta pequena maravilha, agora, uma Impressora SLA Open Source, e com a Qualidade prusa!
É bom...
Introducing Original Prusa SL1 - Open-source SLA 3D printer by Josef Prusa
Prusa 3D by Josef Prusa
Introducing Original Prusa SL1 3D printer, which is based on the MSLA printing process. It uses a high-resolution LCD panel and a UV LED to cure thin layers of resin to achieve an unprecedented level of detail.

Falando de Prusas, podem também GRAVAR, e quem sabe, cortar por Laser CNC, com umas adaptações...
O que vos aumenta as capacidades da vossa Oficina!
Laser Engraving on Your Prusa MK3marzsoltYes, 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.
