3D Printing

203 posts
I find that the best projects start with a purpose, however what most people don't tell you is that the purpose doesn't always have to be prophetic, necessary or groundbreaking. For a lot of people starting a project can be as simple as the intention:   "I want to blink an LED"   When I joined Leeds Hackspace this was the first concept I was introduced to, along with the Arduino platform. This small and, to me, humble beginning has led me down a path which resulted in a change of job, ...
Chemists at MIT have found a way to add new polymers to things already printed, which allows them to create more complex objects that have different chemical and mechanical properties. Blue LED light is used to add monomers to an existing polymer chain resulting in growth. (via MIT)   Research funded by the National Science Foundation helped MIT researchers discover a way to add to, and alter 3-D printed objects after they’ve been printed. Until this advancement, objects that were 3 ...
Possibly the biggest growing technologie today is the 3D printer, this is partly due to its decreasing cost. This drop in cost of 3D printers is largely due to the standardization of the technology as more printers use the same base technologies. The cost of filament however, whether standard or exotic, still remain relatively high.   D3D Innovations has been working to change this. Their filament fabricators allow anyone to create their own filament using various plastics, combinations an ...
A new software developed at MIT enables laypeople to 3D print prototypes of their own design. Much like traditional image editing software, Foundry lets you edit designs, with the added twist that they can be printed 3 dimensionally using up to 10 different kinds of materials (via MIT)   Printing 3 dimensional designs has been around for awhile, but the materials used have often been limiting. Most 3D printers can only print using one kind of material as well.  A lot of good designs e ...
The organ on chip has integrated sensors that allow scientists to test synthetic tissue instead of testing on animals. This organ on chip gets us one step closer to synthetic organs (via Harvard)   It’s easy to forget the importance of organ donors. Truth is there are still people waiting on long lists looking for their chance at survival. If everyone committed to being a donor, there may be chance for everyone waiting, but people are free to not be a donor and that’s just fine ...
A new kind of 3D printing uses flexible polymers that can change shape depending on temperature. Image: A 3D flower changes shape due to changes in temperature. (via MIT)   Making useful things with three dimensional printers has been changing a lot of design and manufacturing processes in recent years. There was the kid who made his own braces, and even 3D printed shoes given as awards at a recent athletic event. All of these objects, however, are rigid: they stay the same after the print ...
So I recently was allowed to play with a 3D printer for the first time (fashionably late to the party, I know), and I ran into a little bit of a problem, what modeling software should I use. I was going to do a once off design but for my employer so It needs to be free, actually free, not this "free until you try to print something" rubbish.   What I want to make is a small enclosure for a proof of concept product I created. I have no experience with big commercial CAD packages like Pro En ...
3D Printing will be available at various UPS Store locations (Photo via Fast Radius & UPS)   Ever wanted something 3D printed but don't have the money to shell out for a GOOD in home machine? Or maybe there are no 3D printing services close by (like a hackerspace or some person with a printer)? With this technology on the rise, it's in-demand and UPS is here to answer the call. The delivery company recently announced plans to launch a full-scale on-demand 3D printing manufacturing netw ...
This project introduces some tips to make a flexible but robust non-flat surface and some other common issues, explaining a possible solution through the making of a smartphone cover full 3D printed.   The object First of all the finished object.   The creation shown in the making of video required four main steps and some experiments: Taking the model dimensions Designing the CAD model 3D printing the components Assembling the components   Calculating the model dimensio ...
This motorcycle looks like it comes from another planet (image via APWorks)   3D printing can do a lot things from making clothes to making food. Now, thanks to the efforts of APWorks, it can make motorcycles. The Light Rider isn't the average hog you'll find riding down the freeway. For one, it looks like something out of the Alien franchise with its hollow, skeleton like design. It's also probably the world's lightest motorcycle weighing only 77 pounds. As mentioned, the bike was create ...

MP3 Player Amplifier

Posted by dougw Top Member Apr 24, 2016
I seem to often have a need to test small speakers, but audio sources these days tend to expect the speakers to have their own amplifier built-in. Rather than always having to hijack some other system and rig up appropriate amplifiers and wiring I decided to make a small test device that can directly drive speakers as low as 4 ohms. Originally, I was just going to build an amplifier, but I found an MP3 player with built-in amp for a ridiculous price of $1.78 with free shipping so this is what I ...
The idea to make yafrd (yet another filament roll dispenser) originates trying to 3D Print some of these useful support available on internet. Unfortunately I too frequently find objects (and not only in this case) that "in theory" will work perfectly but then when having the components in your hands arises mechanical issues making them almost useless or very difficult to use or build. Some of the tools I tried was too complex, other was too expansive and in some cases requiring components t ...

Curios 3D printed sun clock

Posted by gihu Apr 17, 2016
Hi all,   I just wanted to share with you something that I have recently seen, despite of probably many of you have seen it before... It is a digital-style sun clock, here is the link http://www.thisiscolossal.com/2016/02/a-3d-printed-sundial-displays-time-like-a-digital-clock/   For sure there are in this community people who can improve it !! ...

3D printers are great for printing iconic props from the movies. Here is my version of a Star Trek phaser: If you need the file, let me know. ...

Triple Gaff 3D Print

Posted by dougw Top Member Apr 2, 2016
The Triple Gaff project is a solution to carrying heavy objects with narrow handles that cut into your fingers. The Triple Gaff has hooks that grab narrow handles on objects to be carried, but the handle of the Triple Gaff has a large diameter to distribute the load over a larger surface area thus translating the concentrated high stress load from a narrow handle to a low stress load. The shape is designed to be 3D printed with no support structures. It can prevent finger pain while carrying ...
