The Lucien Yeomans “secret” that was almost lost.
Your developing world school needs almost-free machine tools?
Your developing world factory needs unavailable spare parts?
You need a complex part that is too expensive to have made?
Need to bootstrap a factory but only have a few bucks?
No problem!
You just need a metal lathe. Metalworking lathes are necessary to the production of almost everything but are very expensive. In 1915, special lathes made from concrete were developed to quickly and cheaply produce millions of cannon shells needed for World War I. Lucien Yeomans, the inventor, won the nation’s highest engineering award for it but sadly the technique was almost forgotten after the war. We re-discovered it as a way to quickly make inexpensive but accurate machine tools for use in developing countries and in trade schools and shops everywhere. We made modern construction practical by replacing the original poured, non shrinking metal with cement grout.

DIY Microwave Kiln | Fuse Glass in Your MicrowaveShakeTheFuture 

In this Instructable, we'll look into way to make a microwave kiln.
For those who don't know what is a microwave kiln, here is a quick introduction.
Microwave kiln is a kiln that you can put in your regular microwave oven.
It does not use a wire heating element or gas to heat up. Microwave kiln is covered with silicon carbide.
Silicon carbide absorbs microwaves and turns them into heat.
Microwave kilns are usually used to fuse glass.
You can turn broken glass into amazing jewelry.

DIY 3D Printed Dremel CNCNikus
When I got my first 3D printer I was extremely happy with all the new possibilities to create things but after some time I noticed the limitations of 3D printing. Plastic is easy to melt, sometimes it's not mechanically resistant enough and most importantly sometimes doesn't look good. Don't take me wrong here, I love 3D printing and I like plastic (except plastic waste) but there are things that look, work or feel way better when made out of nonplastic material. Imagine all your furniture made out of plastic. Sometimes I prefer wood, when I need strength, metal (mostly aluminum) is a way to go. That's where CNC milling machines are used. Usually, the cost of such machine is really high, most of the hobbyist, small makers can't afford such expensive equipment. That's why the idea of building my own CNC machine sparked in my head

5 Best Open-Source 3D Scanners in 2019Melanie Griffin  

3D scanning is a great companion to the additive manufacturing family. It lets you create models of real-life objects and spaces without you needing to know their design specifics beforehand. 3D scanning does the measuring for you so you can ditch the measuring tape. This is super helpful in a wide variety of industries and hobbies, as it’s a non-intrusive way to replicate 3D objects.
If you’re not familiar with 3D scanners, you can think of them kind of like advanced video cameras. Using a variety of techniques, they capture light in order to generate digital maps of 3D objects.
Once this map is complete, the appropriate software helps you create a replica design of the object you scanned. Within that software, you can either leave the design exactly as is for a direct clone, or you can adjust design details for any improvements or deviations you might want to make.

How To Print Resin-Like FDM Minis on $200+ 3D Printers (Printing The Game #3)

3D Printed Tabletop

In this video I show you how to get even your $200, stock FDM printer printing nearly layerless, detailed, miniatures in no time. No, these aren't meant to be a replacement to resin prints - but this is a great alternative until you can afford an SLA/DLP resin printer. I used a Creality Ender 3 to print the minis in this video, but the profile down below works with other printers in the Creality family as well (like the Ender 2 and CR10/CR10S). I also share the secrets of this profile for those who don't have a Creality printer so you can make your own profiles and/or adjustments to start getting better quality minis on your FDM printers in no time.

Spot Weld Plastic

zimitt

I'm a big fan of the plastic milk jugs. They're a strong, flexible, accessible, free material. There's hardly a jug that makes it to my recycle bin, without a gaping hole of some sort, in the side.
The only problem I had was the HDPE (high density polyethylene) plastic is, it's almost impossible to glue. Glue just won't stick.
I decided I wanted to develop a method to weld this plastic and make it even more versatile.
In his instructable, I'll show my process, successes and failures and I hope you'll find some tips for your own creativity.

Desktop CT and 3D Scanner With Arduino

jbumstead

Computed tomography (CT) or computed axial tomography (CAT) is most often associated with imaging the body because it enables clinicians to see the anatomical structure inside the patient without having to do any surgery. To image inside the human body, a CT scanner requires X-rays because the radiation has to be able to penetrate through the body. If the object is semi-transparent, it is actually possible to conduct CT scanning using visible light! The technique is called optical CT, which is different than the more popular optical imaging technique known as optical coherence tomography.
To acquire 3D scans of semi-transparent objects, I constructed an optical CT scanner using an Arduino Nano and Nikon dSLR. Halfway through the project, I realized that photogrammetry, another 3D scanning technique, requires much of the same hardware as an optical CT scanner. In this instructable, I will go over the system I constructed that is capable of CT scanning and photogrammetry. After acquiring images, I have steps on using PhotoScan or Matlab for computing 3D reconstructions.

Cheap precision drill stand

andrea biffi

When I begun to etch my custom pcb I felt the need to improve circuit drill tecnique. I drilled my first circuits by free-hand with my Dremel, but despite it's very fast, it's subject to errors, and it's also dangerous, because the drill bit is very narrow and weak.

I've searched a column drill as the "Proxxon Bench Drill Press TBM 115" but it's a little too expensive. I've found also a vertical stand for Dremel alt 50€, but it was a model with a single metal column as rail, similar to the most you can see with a "drill stand" search, and it had a low precision in horizontal movement of the bit. In fact you felt the head moving of about a millimeter, which is a lot when your bit is so narrow. So I decided to build it by myself.

3D Printing is So Last Week...Say Hello to "5D Printing" at Mitsubishi Electric Research Labs!

Clare Scott  

 

We all know what 3D printing is – obviously. (If you don’t, here’s a handy overview. Welcome, newcomer.) We’ve also explored 4D printing, which involves printed objects that mutate and morph into different shapes when exposed to an outside stimulus such as light, water or temperature changes. So what’s involved in 5D printing? Printed objects that levitate? Printed objects that teleport? Time-traveling printed objects?!

Well…no. You can 3D print a TARDIS, but you still can’t make it travel. 5D printing is simply another name for five-axis additive manufacturing, and while it may not be as exciting as teleportation, it’s still pretty cool – and useful. The term “5D” as applied to five-axis printing is being used by Mitsubishi Electric Research Laboratories (MERL), the North American subsidiary of the multinational corporation’s research and development branch. They’ve been experimenting with a print bed that actually rocks back and forth on two axes, creating a fourth and fifth axis as a result.

What this means for the final printed part is that instead of being created as a series of flat layers, the layers are curved. William Yerazunis, Senior Principal Research Scientist at MERL, describes the advantages of this process as applied to a pressure cap. A cap printed using standard 3D technology will be quickly ripped apart along the adhesion lines when pressure is applied, he explains. But if that same part is printed with the 5D method, curving the lines where the maximum stress will be applied, the part will be three to five times stronger – and will use 25% less material.
