DIY Desktop 5-axis CNC Mill

i_nerantzis

OK, you bought your router and you are happy with it. If you are an artist. 

But... if you are an engineer... you probably are not so happy.

You cut some 2D stuff. Then try some 2.5D and start getting excited. And then, there comes a day when you start wondering... What if I can make something more out of my 3-axis router?

Then it comes to your mind that you can always convert one of the axis from linear to rotary! Yes this is it! You start doing it... you succeed, but deep down inside you know it.

You have to go all the way to the end and do it properly. You need to make the conversion to a full 5-axis machine to be satisfied! If you feel like it, then follow my lead...

An Unexpected Bioprinting Advantage Over COVID-19

Kerry Stevenson

Researchers have been using bioprinting technology to assist in the development of COVID-19 treatments.

According to a report in the New York Times, researchers at the Wake Forest Institute for Regenerative Medicine unexpectedly discovered a new approach: 3D bioprinted miniature organs. These human-like replications mimic much of the actual body functions, and thus are ideal for use in testing.

The miniature organs, which apparently include lung and colon analogs, offer a trouble-free testing platform that doesn’t risk any human or animal well-being. In addition, these miniature organs are far more closely related, biologically, than mammals that have previously been used for testing.

There’s another advantage in that these bioprinted organ analogs can be continually monitored, unlike, say the lungs inside of a test subject, which are a bit hard to access. In this way those performing tests can directly observe the effects of their prototype treatments.

A tecnologia LIDAR em Apps vai-os permitir scans com muito mais fidelidade:

First LIDAR 3D Scanning Apps Appearing

Kerry Stevenson

There’s now at least one new app that takes advantage of Apple’s new LIDAR capability.

A few months ago Apple unexpectedly announced a new iPad Pro model equipped with LIDAR. LIDAR is a range-sensing technology that is often used in high-end equipment for 3D scanning, particularly for landscapes. Seeing it appear in an affordable consumer tablet was quite a shock.

Apple’s intention was to provide additional sensor information to aid their Augmented Reality operations. In other words, when you’re pasting that virtual IKEA couch in your living room view, the couch is positioned more accurately.

However, the presence of a new 3D scanning sensor in an iPad obviously hints that someone would, sooner or later, develop a specialized 3D scanning app to make good use of it.

That now seems to have happened, with startup SiteScape now beta-testing just such an app

Toy Crossbow

NobodyNothing13 

I started designing this crossbow in Tinkercad a while back, and it came out pretty well. After I finished, the design just sat untouched. Recently, I have looked back at my old design, noticing it still had many issues, like the fact that you had to use hot glue to assemble it, the striker was very short, nothing held the marble in place, it wasn't very powerful, and so on. So, I started refining this design, and fixed a lot of problems and made this crossbow easier to use, easier to assemble, more powerful and more accurate.

I made this toy crossbow to be a toy, and also part of a game. You can just launch marbles around for fun, but you can also play a game with these, with as many players as you want. In the game, you have a crossbow, some marbles, and 5 targets (I used plastic army guys). Then, you take turns shooting at your opponent's targets. You launch a marble, they launch a marble, and so on. I usually draw boundaries of how close your crossbow can get to your opponent's targets. You are eliminated if all 5 of your targets fall, and the last person who still has standing targets wins!

In the rest of this instructable, I will tell you how to print, assemble, and use this crossbow.

2D to 3D, Image to Svg to 3D

Edgar

I've become fascinated with those X-Ray Videos of working Mechanisms, and so, I wanted to make some MDF cut plates of them, just for fun.
So, I went to the Net to search for some 3D Files, but the ones I've found are crap, either Homemade Firearms, or 3D for movies, so I went to do them from scratch.
Here's my tips on how to do it;
How to turn any 2D image, into an Object, or into many parts of a 3D Project.

Battery Cases for Electronic Kits.

liquidhandwash

If you have built one of the cheap electronic kits featured in my previous instructable, you probably want to put in some sort of case. Having your project in a nice looking case will really make your project look great and will impress your friends much more than a naked PCB with wires and a battery hanging off it. Your project should be something you can be proud of, take to a job interview and say look what I made!
This instructable will show you whats possible with a little thought and a laser cutter.
There are four types of cases shown here,

•  Case without a battery or switch: The easiest to make but you will need to run a lead to your power supply.
•  Case with a battery: Great if your kit has a switch.
•  Case with a battery and switch: The most challenging to build, but some kits don't have a switch.
•  Case with a push button, battery and switch.

97 Examples of Tech-Free Toys

Katherine Pendrill

From DIY Paper Box Puppets to Wooden Coloring Books

While miniature robots and app-controlled playthings may be on the rise, there is still a growing demand from consumers for simple tech-free toys that allow children to embrace their imagination. Made from minimalist materials and featuring straightforwards designs, these timeless toys prove that children don't necessarily need the latest high-tech products.
For boys, there are a number of tech-free toys that are heavily focused on building. For example, there are home-inspired wooden building blocks, cardboard architecture kits and paper-based medieval toys, all of which offer boys the possibility of building their own creations from simple and uncomplicated materials.
For girls, these tech-free toys offer creative and artistic options that go beyond traditional plastic dolls. Some of the most innovative toys for girls are empowering coloring books, DIY paper doll crafts and miniature felt garden play sets. Despite their simplistic design and lack of smart technology, these tech-free toy options for girls are extraordinarily imaginative and highly educational.

The amazing science behind HP’s new full-color 3D printers

Garage Staff

Today, HP unveiled its groundbreaking low-cost, full-color 3D printers at the annual SOLIDWORKS World 3D design and manufacturing trade event. The new HP Jet Fusion 300/500 printers are an industry first: capable of creating production-quality prototypes quickly, accurately and affordably — making advanced 3D technology accessible to a wider swath of digital innovators. And this huge leap forward in 3D printing began as HP explored a surprising realm of light — one that we’re unable to see.
Cheryl MacLeod, HP’s Global Head of 3D Fusion Science, leads the team of scientists and engineers at HP’s 3D Open Materials and Applications Lab in Corvallis, Oregon who are charged with developing the science behind the company’s portfolio of 3D printing materials. “We ultimately think of printing as a way to convey information,” says MacLeod. “And with 3D color printing, we now have an entirely new language.”
Breakthrough 1: Seeing the light
In developing the new Jet Fusion technology, HP’s 3D R&D teams called on the company’s deep expertise in the science of ink to create black fusing agents able to absorb heat at greater speeds, as is needed for 3D printing. But printing color with exclusively black agents isn’t possible, so a new solution needed to be found.

The new HP Jet Fusion 300/500 printers are an industry first: capable of creating production-quality prototypes quickly, accurately and affordably.
HP’s scientists realized that they needed a primer coat of white on the outer layers of the black parts being produced so that color could be applied and fused. But how could you create a layer of white when all available fusing agents were black? A new kind of fusing agent was needed, so that the surface of the fused part remained white, but absorbed heat as well as black. And they found the answer in an unexpected realm of light — one that we’re unable to see.

Camera rig for Workbench hands-free videos

Edgar 

I wanted to film some workbench videos, and always got frustrated with the results of fixing the camera, and the small tripod, to the workbench, and so. So I got to thinking, how about some kinda rig for an handheld camera, that would leave your hands free, AND still allowed you to move back and forth, and around the workbench? Here's what I came up with, you strap a backpack, with a cardboard box inside, and a block of styrofoam with slots for the tripod, plug the camera&tripod into it, and with some rubber band, Voila, hands-free videos!

“Imagination will often carry us to worlds that never were, but without it we go nowhere.” – Carl Sagan

Let’s face it, Instructables community, rockets are cool!

Every type of rocket, from the AWESOME new SpaceX rocket that can actually land, all the way down to the tiny rockets like the Matchstick Rocket by IbniH, is amazing!

I have always wanted to have my own rocket. So, I did what any individual with imagination does, I built one. I used PVC pipe for the launch pad and rocket, and for my fuel, I use vinegar and baking soda.
