Build Your Own (metalworking) Lathe - Part I
corradini

You can make an entire machine shop worth of power machine tools, using basic hardware store/home center supplies and scrap metal. Melt aluminum in a metal-pail furnace, using sand, charcoal, and a clay flowerpot! Cast sophisticated metal tool parts using supplies from a gardening shop and modified kitty litter! End up with a full machine-shop lathe ("the only tool capable of making any OTHER machine-shop tool, including itself!") for just the cost of your time, some scrap steel and aluminum, and a motor!

Customizing Indoor Wireless Coverage via 3D-Fabricated Reflectors
Abstract

Judicious control of indoor wireless coverage is crucial in built environments. It enhances signal reception, reduces harmful interference, and raises the barrier for malicious attackers. Existing methods are either costly, vulnerable to attacks, or hard to configure. We present a low-cost, secure, and easy-to-configure approach that uses an easily-accessible, 3D-fabricated reflector to customize wireless coverage. With input on coarse-grained environment setting and preferred coverage (e.g., areas with signals to be strengthened or weakened), the system computes an optimized reflector shape tailored to the given environment. The user simply 3D prints the reflector and places it around a Wi-Fi access point to realize the target coverage. We conduct experiments to examine the efficacy and limits of optimized reflectors in different indoor settings. Results show that optimized reflectors coexist with a variety of Wi-Fi APs and correctly weaken or enhance signals in target areas by up to 10 or 6 dB, resulting to throughput changes by up to -63.3% or 55.1%.

Build Your Own Inexpensive Powerbank with 3D Printing
Matthew Mensley

Instructables user Nematic! details how to make your own portable powerbank from laptop cells, 3D printing and a little electronics savvy.
We’ve all experienced that unique feeling of helplessness and anguish that only a dead cellphone battery can bring. Cut off from the internet and contact with others it becomes impossible to navigate, and what the heck are you supposed to do while sitting around waiting for the bus/train/plane. It sucks.
Fortunately there’s no shortage of inexpensive power banks knocking around to keep you topped up with juice on your travels. But for the thrifty with time to kill and a handful of old laptop batteries lying around (a common scenario, we know) there’s an alternative.
In a short-and-sweet post over on Instructables, user Nematic! shows us how with nothing more than a few tools (3D printer, soldering iron and glue gun), a cheap powerbank module and some 18650 cells, you can make your own smartphone powerbank lickety-split.

Moldes impressos em 3D? E uma Oficina arrumada, um Manual de Injecção de Plástico, Parafusos & Porcas, e Salvemos o Filamento!

Isto é que é explorar a 100% as possibilidades da Impressão 3D!
Porque é lenta e cara, a Impressão 3D deve ser usada para produzir Moldes para injecção de Plástico, o que só DEPOIS resulta na producção em série de objectos, como deve de ser...
Aprendam como é que o podem fazer, com estes nossos amigos da Pinshape, que aconselho a subscrever:




Low-Cost Injection Molding Using 3D Printing
Pinshape Blog

It’s no secret that 3D printing is a great tool for affordable production of custom objects. With new 3D technology like the Formlabs Fuse 1, there are a variety of options availible for small batch production needs that help manufacturers save on cost-per part. However, in some cases injection molding is still ideal for scaling production needs.
In this post, you’ll learn how to combine 3D printing and injection molding for small batch production. By using 3D printing to cost-effectively produce your molds and injection molding to rapidly produce identical copies, you leverage the benefits of both technologies. In this tutorial, we’ll go through the process of designing your mold, choosing a material, and producing injection molded parts. By the end, you’ll have the knowledge to access the speed and cost-efficiency of injection molding processes.

Prova brilhante da Graça e Génio Femenino, a nossa amiga darbinorvar mostra aqui como se pode ser Engenhocas sem deixar a casa num Caos, com este Instructable que ensina a ter uma ordem e organização invejáveis, sem ter medo, no entanto, de trabalhar nos vossos projectos...
Muito bom.






How to Create an Amazing Workspace at Home
darbinorvar

The idea is to create a functional and practical work area within the home that's accessible to all family members, friends, and co-workers. If you're looking to introduce your children to the world of making, or simply make it a bigger part of your everyday life, then there is a lot of appeal in creating a versatile area that automatically becomes the go-to place to fix broken things, learn new subjects, try out new projects etc.... While many people would automatically want to hide such a space in the garage or basement, it's a nice idea to make it a very central part of the home - by giving it such a prime location you communicate what an important part of your life this is or could be, and you make it easier for work to take place.

Adding Screw Threads to 3D Printed Parts
Downloads , Tutorials

At Formlabs, we design lots of functional parts for printing on the Form 2 (our stereolithography, or SLA, 3D printer). These parts include things like internal prototypes used for R&D, jigs and fixtures that will be used on our manufacturing lines, and parts for design reviews before the final part is injection molded from a material like nylon.
No matter the application, we often find ourselves needing to combine multiple parts using screws, and now that we’ve released an improved formulation of our Tough engineering resin, the differences between “looks like” prototypes and functional prototypes are decreasing.
This article is a guide to using screws in 3D printed SLA parts. There are many other ways to attach multiple 3D printed parts together, but if you need to repeatedly attach and detach components and want robust mechanical fastening, there's no real replacement for genuine metal threads.

7 Free STL Editors + How to Edit and Repair STL Files
Frederik Bedrich

How do I edit STL files? That is something any 3D printer owner sooner or later wonders. After all: Ready-made STL files are fine. But what if an STL file you downloaded lacks some features, is damaged or you need only a part of it? That’s when you need an STL editor.

How to Make DIY 3D Printed Parts for Just About Anything
Frederik Bedrich

We’ve all been there. You fiddle about with a gizmo or furniture piece of some sort in the home and a piece just snaps off. Shoddy flimsy plastic is the culprit, and the irritation it brings is endless. Gluing the piece doesn’t help, and you resign to living with the original doodad as a shadow of its former self; functionally fine, probably, but still not quite right.
What if we were to tell you that there’s an answer to replacing such non-essential but easily missed parts? It’s rather simple — make it yourself! With the lowering in costs for personal home 3D printing, and the rise in competitively priced print bureaus, acquiring replacement 3D printed parts is a cinch.
So settle in and read along as we outline the ins-and-outs of creating 3D printed parts for games, toys and other such home objects.

Casio Mofrel 2.5D printer makes realistic fabric and leather samples
Brittany A. Roston


Casio is the latest company to showcase a cool new technology at Japan’s CEATEC event. The company recently demonstrated Mofrel 2.5D printing, an almost-3D printer that can produce materials with a texture like that of leather or fabrics. With this technology, sheets of textured ‘leather’ and ‘fabrics’ can be printed on-demand with various designs, then colored through a separate printing process.
Whereas 3D printers produce objects layer by layer out of plastics, Casio’s 2.5D printer is able to print very thin layers onto sheets of paper. These layers mimic the texture of materials, giving designers a fast on-demand way to test out a design, including getting a real-world feel of it, before creating actual samples with actual materials.

Enquanto não se vislumbram Impressora 3D de Metal, a preços mais acessíveis, eis como se faz, para transformar os vosso objectos, em peças metálicas:





fusion3dmodels

Molding metal by conventional casting methods can be an expensive, time consuming endeavor. However, with 3d printed molds and low temp alloys, it is now possible to create 3d printed molds quickly and cost-effectively as shown here. The final molded pieces can be sanded, polished or painted and withstand more punishment than 3d printed pieces will. Now, you can go from concept to CAD to metal casting in less than a day!

Making a 3-D Printed Mold
rachel

I recently had a project where I needed to create a couple dozen identical foam ear shapes.  Casting from a mold is the clear solution here.  However, the ears needed to fit onto an existing product, so I knew some tweaking of the design would be necessary to get it right before I could make the dozens. I was able to use Instructables' Objet Connex printers to make my molds, based on CAD drawings I made, and after a couple tweaks I got the design right and was able to make the full run.
In this Instructable I'll share what I learned about how to draw a CAD for a mold and 3D printing it out. I will assume you have access to and moderate proficiency with a CAD system (it doesn't matter what kind). For the printing, if you want to make your own but don't have access to a 3D printer, there are many services which print for a fee, or Instructables may be able to do that for you. The actual casting I will leave out as I was using an expanding polyurethane foam, which is not a generally applicable material.

Construír Robots! E Visão para os quase cegos, uma Serra de lixar(?) Óculos de sol de frascos, e Lego das Impressoras!

Querem fazer o vosso Robot, em casa?
Aprendam com o nosso amigo DJ Harrigam, como o podem fazer, um Manual de categoria, para fazer toda a espécie de Robots:



Designing And Building A Robot
DJ Harrigan
Introduction To Robotics And Robot Making  
For a hundred years, robots, automatons or otherwise synthetic assistants have been part of our popular culture. While they’ve mostly been restricted to the silver screen, thanks to increasingly affordable and powerful electronics, making robots has never been easier. Now, if you’ve got the determination and a few bucks to spare, you can design and build a robot to your liking. Maybe even a cool MeArm as depicted in the illustration above. 
Although robotics is more accessible than ever, any robot is a complex system and requires at least a basic understanding of electricity, mechanical design and programming to create. Never fear! My goal is to explain the high level concepts that make for a successful robot as well as point to the right tools and materials that the bot builders of today are using in their designs. It is a challenge, but there’s nothing quite like taking raw materials and making them come to life. Let’s get started! 












Algo que importa divulgar por todo o Mundo Lusófono, os quase-cegos poderão VER outra vez, com esta maravilhosa Enhenhoca, por isso, cá vai a Referência:







How Does eSight Let The Legally Blind See? 
eSight houses a high-speed, high-definition camera that captures everything the user is looking at. eSight’s algorithms enhance the video feed and display it on two, OLED screens in front of the user's eyes. Full color video images are clearly seen by the eSight user with unprecedented visual clarity and virtually no lag. With eSight’s patented Bioptic Tilt capability, users can adjust the device to the precise position that, for them, presents the best view of the video while maximizing side peripheral vision. This ensures a user’s balance and prevents nausea – common problems with other immersive technologies

Guide: How to Finish 3D Prints

brett 
While I have 3D printed hundreds of designs over the years, not once have I taken the steps to finish a single print. There are plenty of videos and articles covering the process but they are often a general overview and leave out small but important bits of information. For someone inexperienced like myself who prefers to follow explicit instructions, the artistic process can be a rather daunting task. Unfortunately I purchased my 3D Printers for costume and prop design and can’t leave them unfinished forever, where this guide will cover my successful, albeit awkward adventure into the task of post processing 3D prints. 













Não sei se não se poderá usar isto para cabeças de extrusão das Impressoras, ou mesmo para os Computadores sobrecarregados dos Engenhocas, mas já para estas Câmaras espectaculares, é uma Maravilha...

Por isso, estes Programas Grátis, que encontram na Net, são tão importantes!







CraftWare
Overview 
CraftWare is a FREE, fast, easy-to-use slicer software that converts your digital 3D object into a .gcode toolpath format understood by most 3D printers.
CraftWare primarily works as a slicer for solid 3D digital objects, but it is also an excellent tool for many other tasks. You can interactively manage your prints, thus reducing build time and finding the optimal build supports. CraftWare also utilizes the most impressive gcode visualizer on the market; this allows you to see each print layer-by-layer, from any angle, easily allowing you to detect any places that you may want to modify before printing. It is basically like seeing a finished print in front of you before you press the start button.
CraftWare utilizes dual channel communication for real time interaction between the software and the printer -just another great tweaking option.
