How to 3D Print Hollow Objects – Simply Explained

Pranav Gharge 

Have you ever wondered whether hollowing out a model is a good idea or not? Well, the simple answer is that since 3D printing is a volume-based production technique, there’s almost always a benefit to some degree of hollowing out of a print. Hollowing can save you printing material, time, and money, and of course, potentially improve your prints.

In this piece, we’ll discuss hallowing prints in general for FDM, SLA, DLP, and LCD (resin) printing. Then, we’ll focus on the three main ways to hollow out your prints: with a slicer, vase mode, or a modeling program (we choose Meshmixer as our example). And finally, we’ll go over some considerations for when and how much to hollow.

Bending steel with plastic 3D printed toolsStuff Made Here 

I've been wondering if 3D printed tools could possibly bend steel. It seemed possible unlikely. I designed and printed several tools which are used on a hydraulic press to bend and form steel sheet metal. This particular tool could be made by CNC machining the tools from metal but 3D printing it is much faster and easier

Designing a Parametric "Print in Place" Hinged Container Using Autodesk Fusion 360
gzumwalt

The eight different size and color 3D printed "print in place" hinged containers appearing in the cover photograph of this Instructable do have one thing in common; they were all printed from a single Autodesk Fusion 360 model using "parametric modeling".
In a CAD environment, a parametric model is a model whose size and / or shape may be altered simply by changing dimensional values. In this model, I specified the dimensional values in the Autodesk Fusion 360 "Change Parameters" menu for the Length, Depth, Height, Thickness and Tolerance dimensions of a simple "print in place" hinged container. I then designed sketches for the base, lid and ball and socket hinges, and extruded the various components, using the dimensional values I entered. Thus to change the length of the container, I simply change the Length dimension, to change the depth, I change the Depth dimension and to change the height, I change the Height dimension. When any of the dimensional values on the Change Parameters menu are altered, Autodesk Fusion 360 rebuilds the container to the new dimensions, creating a new model ready for 3D printing, thanks to parametric modeling.

Making Aluminum Bronze: Melting Copper and Aluminum
matt.e.jenkins

Aluminium bronze is a type of bronze in which aluminium is the main alloying metal added to copper, in contrast to standard bronze (copper and tin) or brass (copper and zinc). A variety of aluminium bronzes of differing compositions have found industrial use, with most ranging from 5% to 11% aluminium by weight, the remaining mass being copper. The alloy I made consists of 11% aluminum and 89% copper. I personally made these just for the joy of creating and learning how to make alloys. If you have the resources to safely melt metal, then give this a try.

Magnetic adhesive tape for flexible attachments

If you want to attach something quickly and flexible to metal surfaces, magnetic adhesive tapes are very helpful. As if by magic they can attach objects to a fridge or metal shelf, for instance. You can remove them without residue whenever you like.
You can also stick the magnetic adhesive tape to the backside of decorative objects and make them your own magnets.

Manifold applications for the magnetic adhesive tape for private and business use:

•  Hanging up of seasonal decoration, such as advent calendar, monthly calendar, etc.
•  Mounting temporary signage, e.g. "We are on lunch break" for the store, office or practice

Moving Things (and Lasers!) Using Printed Circuit Boards

marciot

In this Instructable, I will share my experiments in making a set of PCB electromagnets for motion control.
For about a year, I have been experimenting with dual-axis pointing mirrors for lasers. Initially, I build a laser steering module out of solenoids. Then, I acquired some Texas Instruments TALP1000B modules from a scientific surplus outlet and experimented with those.
The Texas Instruments module had the advantage of being fantastically small, but it was very fragile and is no longer available for purchase. My DIY module had the advantage that had a clear (rather than gold) mirror, allowing it to work with violet lasers and phosphorescent screens. The DIY module was also robust and could be made from easily sourced parts. The downside was the solenoids made the module large and heavy and they could only provide a pulling force, complicating the driver circuit and limiting control.

Pocket Pi - a Raspberry Pi Computer for Under $150
TheInventionMaker

This is a affordable $100 raspberry pi computer. This computer is not the thinnest or prettiest thing on instrutables. This is for getting the job done. The shell is 3D printed. There is 1 charging port, for the motherboard. The keyboard has a wire designated for charging the keyboard and will not be noticeable on the outside. There are 3 USB 2.0 ports are for input. 1 will be used by your bluetooth + wireless USB stick. Luckily, I have included a USB holder that holds your USB's.

The screen is 4.3 inches and is not a touchscreen. You can easily make it touch screen compatible. The raspberry pi is a zero. This is because the Adafruit Kippah currently does not support the zero w. You will still need a wifi network! It runs NOOBS, but you can still download PC games on it. All you have to do is to search on google how to install PC games on NOOBS.

You can use this to check up on things, play games, and use applications that are normally on PCs. It can do a lot of things that phones can do, but the computer is significantly cheaper. The parts are spread across 3 different websites. If you do not have a 3D printer or a soldering iron, you will have to but different parts. This will be explained in the steps. It should take you around 1 hour to build, but with shipping times and how long your 3D printer takes to print the parts, it could be longer.

Um Motor feito com Ímanes Permanentes, que é um Anel, com a Hélice no meio!
Vejam o Vídeo, para perceberem as vantagens dum tal Sistema, que vale a pena...

Rolls-Royce | Permanent Magnet Technology

The AZ-PM thruster is the latest in a range of Rolls-Royce propulsion products using its permanent magnet technology. This technology is based on electric drive where the motor is in the form of a ring round the propeller. The moving part of the ring is a rim around the propeller blades which carries a series of strong permanent magnets. The rotor, fitted within a series of magnets, turns within an outer ring which form the stator. When current is supplied to the motor from the variable frequency power supply the electromagnets are excited in a particular sequence and the resulting magnetic fields interact with the field from the rotor magnets creating a torque that turns the rotor and its propeller blades.

Revolutionary 3D printed magnets by Polymagnet can change engineering as we know it 

Alec 

We’ve all played with magnets when we were younger. And to a kid, they are pretty magical with one attracting and one repelling side – until you find out about magnetic fields in high school. However, those conventional magnetic are actually quite limited, as the pioneering work of Correlated Magnetics Research (CMR) proves. The startup has been working on revolutionary new magnets, featuring 3D printed magnetic fields called Polymagnets that can be customized for any purpose – from very tight magnetic twisting seals to ‘magnetic’ springs that seem to float thanks to equal amounts of attraction and repulsion. A technology that can change engineering as we know it.

Weaving baskets with newspaper

dezine

I have just discovered how easy it is to weave a basket using newspaper! It's so simple to roll paper tubes out of newspaper and then weave the tubes into a basket. You can bet I will be making plenty of these faux wicker baskets for future projects, as well as for storage in the home.

I discovered this post on a Russian website and the instructions don't quite make sense, so I started putting together my own paper weave basket using newspaper that I normally keep for cleaning windows and messy projects.
