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.

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!

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.

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.

Researchers Make Robots Out of Paper 

A team of researchers from the University of Illinois Department of Mechanical Science and Engineering has made a pair of crawling robots, Peri and Poly, out of little more than a sheet of paper, a few 3D printed parts, and a handful of screws.

The researchers used origami paper folding to create cheap robots that move like earthworms.

Poly is 51 mm wide and uses a pair of origami towers that expand and contract when twisted to make the worm robot crawl forward. The robot has directional feet made of hard plastic and rubber. The 3D-printed toes allow the robot to slide forward while the rubber heal stops it from backsliding. This particular example of bio-mimicry was inspired by the setae on earthworms.

Peri is more than twice the size, and fully mobile. Peri is 106 mm wide and runs on batteries unlike the Poly, which is tethered to the power source. Peri also uses on-board controllers to navigate.

The Problem

 

Over 1.2 billion people globally have no access to electricity and millions more have an unreliable supply. Instead they use dangerous, polluting and expensive kerosene lamps for light.

A typical kerosene lamp is made by taking an empty bottle or tin can, putting a wick in the middle, filling it with fuel and lighting. Using kerosene for lighting is extremely inefficient, dangerous and expensive, and it has extensive health and environmental drawbacks.

How It Works

Combining kinetic and potential energy, GravityLight works by connecting an elevated weight — filled with rocks or sand — to a pulley system that slowly powers a generator as the weight falls to the ground.

Para se divertirem um pouco, fiquem com esta ideia, que é uma boa maneira de renovarem a Novidade dos Fidget Spinners:

Electromagnetic Fidget Spinner Accelerator

tanner_tech  

Fidget Spinners are little plastic toys with a bearing in the center. They are fun for a little bit, but get boring after a while due to their slow spinning speeds. There are ways to make them spin faster, but these methods involve using a bulky air compressor or an expensive can of compressed air. Luckily, I have found a cheap way to accelerate these fidget spinners to extremely high speeds with the power of electromagnetism. You can even hold the spinner in your hand while you accelerate it! I have clocked a spinner that is spinning with this accelerator at speeds up to 1440 RPM, that is fast. You can build this accelerator too, it is really cheap and really simple to build.

Uber Lighter 2.0

lonesoulsurfer

Burn everything in your path with the updated, ups-scaled and most awesome of lighters
This build is easier to build, you can change the wick simply and without any fuss and ascetically, it’s a much better looking and hardier lighter (in my humble opinion). Also it's around 40% larger as well! The size of the lighter will depend on how long you make the body section. I decided to make this version even bugger than the first.
Instead of fabricating a sparker section as I did in this 'ible, I went down the easy road and brought one on eBay. I’ve also added a screw cap to the end so filling-up the lighter and changing the rope (which you probably won’t do for years) is a tonne more easier to do. Also, the lighter is all made from off the shelf parts that you can buy from most hardware stores.
