DIY Desktop Spot Welding Machines

I was looking for a cheap spot welder to make some welds on few 18650 modules, but I couldn't find aynthing affordable for my country. I found two projects with upcycled transformers which are the basis for DIY spot welder.  Making this could be dangerouse. Stay safe!

DIY Bench Clamp Made On a 3D Printer

Chuck designed and made this very useful bench clamp on his 3d printer. It uses some M6 metal bolts and nuts but it can easily be converted to other sizes.





It goes through a hole in a workbench and holds objects safely in place so you can work on them.

3D Printable Mortise and Tenon Jig for your Dremel

If you need a cheap DIY jig for mortise and tenon making for your woodworking projects here is a simple 3d printable version that uses a Dremel tool for cutting out the wood.
It was developed by Crafted3D since he needed a cheaper alternative for a 1000USD standard router.

There are a few non-printable parts like a metal clamp, but this is a great low-cost shop tool. You could also design different templates for the shape of your tenon/mortise parts.

3D Printable DIY Rotary Tool aka. Dremel Clone

Makernaut developed and published this great 3d printable rotary tool or Dremel. It looks easy to make even with entry level electronics skills and has three 3d printed enclosure parts.

It is powered by 12V DC motor (listed as 6000 rpm, RS-550S motor, diameter~37mm), it has PWM DC motor controller (3A) and mini chuck / collet set for 3.17mm shaft to hold the tool bits.


Here is the build guide video with a short demonstration:

3D Printable Hand Saw Made from HTPLA Carbon Fiber Filament

Josh Hughes 3d printed a somewhat functional hand saw from carbon fiber filament. It is made from Protopasta HTPLA carbon fiber material and it can cut tough small pieces of soft wood but the laers separate due to cutting forces.
Josh notes that it could be prevented by applying a cyanoacrylate coating.




Josh has a currently small YouTube channel, but I think it will be worth following:

What if you could carry a small 3d printer everywhere?

What if you could carry your 3d printer with you as a small bag? What if 3d printers were everywhere? Researchers at HPI explored this possibility with actual hacked 3d printers and 3d printing pens to  test the implications on everyday life.
It would basically give you magic power to repair and replace everything on the spot with incredibly low cost. Sure, we are not there yet, but technologies and concepts are slowly converging to this point.

Here is a detailed talk by Thijs Roumen about the entire concept, the research conducted and the results:



Here is a video focused on the mobile printing process:




They used modified M3D machine which was cut down to more compact size of 9cm in hignt, equipped with a UDOO control PC computer, shoulder strap and a battery. I expect that someone will make simillar open sourced machine soon.

NinjaFlex 3D Printed Metamaterial Mechanisms

Team of researchers at Hasso Plattner Institute, Potsdam, Germany developed a technique that gives internal structure to objects that they printed on Ultimaker 2 in NinjaFlex filament. Since the structure is designed it gives the object mechanical movements enabling it to act as a tool or a device. 

From project description:

Recently, researchers started to engineer not only the outer shape of objects, but also their internal microstructure. Such objects, typically based on 3D cell grids, are also known as metamaterials. Metamaterials have been used, for example, to create materials with soft and hard regions.

So far, metamaterials were understood as materials—we want to think of them as machines. We demonstrate metamaterial objects that perform a mechanical function. Such metamaterial mechanisms consist of a single block of material the cells of which play together in a well-defined way in order to achieve macroscopic movement. Our metamaterial door latch, for example, transforms the rotary movement of its handle into a linear motion of the latch. Our metamaterial Jansen walker consists of a single block of cells—that can walk. The key element behind our metamaterial mechanisms is a specialized type of cell, the only ability of which is to shear.

In order to allow users to create metamaterial mechanisms efficiently we implemented a specialized 3D editor. It allows users to place different types of cells, including the shear cell, thereby allowing users to add mechanical functionality to their objects. To help users verify their designs during editing, our editor allows users to apply forces and simulates how the object deforms in response.

Personally I find that the software for design of those metamaterials is the most interesting part and would be of great use for DIY and Maker community. I don't know who has the property rights to that code, but I think if the research was funded by public money the code should be open sourced.
