Full print process of Kühling&Kühling 3d printer

Video demonstrating full print process of Kühling&Kühling  3d printer. It looks like very high quality print. The printer is available for 4.153,10 € plus shipping. The price is high and there is no independent reliability or problem reports due to novelty so it makes cost-benefit analysis harder at this moment. It looks like solid piece of German engineering and Kühling-s claim it is built for reliability. We will see ...

Open source watch with 3d printed case

OTM-02 is open source watch module project with DIY 3d printed case.

https://github.com/hairykiwi/OTM-02

http://forum.energymicro.com/topic/582-otm-02-open-source-time-machine-2/

 
Cases

A non-waterproof, DIY 3D printing optimised case design is at an intermediate stage of development.
Other cases designed to be 3D printed in metal or other high-resolution materials are also being worked on as time permits.
The intention is to publish the source CAD data for at least one DIY 3D printable case design before the end of April 2013, earlier if possible.


Objectives:

• Create a watch module that enables the end user to have complete control of its functionality and user interface,
• Discover the benefits - and any detractions - of (potentially selling) a product developed from the outset in true open source hardware style,
• Self-education,
• Discover how much technology can be crammed into a wristwatch designed - and possibly manufactured - 'on the living room table',
• Design a module that with only a little extra effort, could form the basis of other devices, eg cycle computer, dive computer, data logger, etc.

Features:

The project utilises the following parts and features:

• EFM32LG332F256 - A USB enabled, Energy Micro ultra low power Leopard Gecko,
• A 128x128 pixel (23.2 x23.2mm visible area) ultra low power Memory LCD from Sharp Microelectronics,
• Recharge and programming via USB Micro B connector,
• Programming via ARM Serial Wire Debug (SWD) protocol also available,
• 150mAh Li-Po Battery + on-board battery fuel gauge IC,
• Vibratory Motor,
• Piezo Electric diaphragm,
• Five miniature right-angle tact switch buttons, (By MCU pin assignment and feature-set native to the EM MCU, with minor board layout editing, provision exists for alternate UI methods such as capacitive touch buttons.),
• Provision for a LED based planar light-guide type back light (utilising a 0.4mm high right-angle Avago ChipLED and laser engraved light guide. (N.B. This is highly experimental and yet to be fully developed. Any derivatives of OTM-02 with commercial intent should be aware this technology is heavily patented.)
• Possible feature additions in modules developed subsequently include: accelerometer, Bluetooth LE, ANT+, GPS

Update (3.5.2014.):

Here is new OSWatch design that won Make's Arduino challenge:

3D printed knives projects

This post will compile news and data about 3d printed knives and blades.

This was the first video of 3d printed knife I saw:

I don't see it is good for anything except cake cutting.





Update (28.2.2014):

here is another 3d printed tanto style blade in ABS by Barancules. You can open cardboard boxes with it ... still, far away from usable knife IMHO

Here is  karambit style blade:




Update (16.3.2015.):

... and then someone has to ruin it for everyone ...
As 3dprint.com reports, mechanical engineering student at École de technologie supérieure in Montreal, Canada, named Antoine Rancourt Poulin made a hidden real knife blade with 3d printed comb attachment and handle. Probably highly illegal as concealed weapon ...

Source: http://3dprint.com/51252/3d-printed-comb-knife/

Update (24.4.2015.):

Group of Dutch students wanted to show security flaws and smuggled two 3d printed knives into a courtroom of the Palace of Justice in Den Bosch. The whole thing was done with courts permission as a sort of a test.
3D printed knives were tested to show that they can cut, stab and potentially hurt someone.

What is next? Taking some sharp wood sticks or stones trough metal detector to "prove" some sort of security threat?

From the source:

According to the court’s spokeswoman Ilse Westenenk, the courtroom regularly works together with the college. ‘That’s why we gave them permission, but obviously after checking they were actual Avans students,’ she said.

The spokeswoman further revealed that the court was already aware of these loopholes in the security system, but added that this experiment will not lead to a tightening of security.

‘We have known for some time that knives of this kind cannot be detected by metal scanners. 3D printed weapons simply require other security measures. But for now we will uphold the current balance between security and transparency,’ she said. The courtroom and its corridors are also patrolled by security personnel.

Update (23.6.2015.):

I attended an event about 3d printing in Osijek, Croatia and in a bunch of 3d printed stuff I saw a small 3d printed knife of the same design as used by Dutch students. I took a look and it seems completely useless. I don't think it would be capable of opening a paper envelope. Maybe it could be used to cut some very soft cheese. Waste of time. you can see it in picture bellow:

Update:

Here is a dagger printed on professional Stratasys SLS printer probably in nylon powder. Not much information is available. The source is unknown. It looks like Klingon design :-)

Update:

here you can see a knife prototype or fantasy prop developed and 3d printed/painted by SoupCan13

Update:

Here is a serious and fully functional sharp metal knife 3d printed by laser sintering in titanium. The knife was developed for a sailing team as a safety tool. It must be very expensive.

Here is a DIY steak knife printed in some unknown organometallic filament which looks like more usable eating utensil but still bends:





Here is a kitchen knife printed with Protopasta's HTPLA carbon fiber filament by Josh Huges. It "cuts" the fruit and veggies but it is probably not so sharp.

RepRap Therminator 5 Hot End

This is Kickstarter project for RepRap hot end for more demanding print jobs.

http://www.kickstarter.com/projects/1506241372/reprap-3d-printer-therminator-5-hot-end

Features of the Therminator 5

• A large heat zone for temp stabilization. 
• Machined brass for better heat transfer and durability. 
• Double heat power resisters for fast heat -up and heat zone stability for fast print jobs. 
• A thicker insulator (PEEK) for heat isolation and durability. 
• Only has five total parts making it very easy to maintain. 
• The nozzle comes off without taking the extruder or hot end apart. 
• Uses SeeMeCNC nozzles that are always available and cost less than other nozzles you have to buy (if in stock) 
• The mount is common for most RepRap Mendel and Prusa extruders.
• RepRap open source hardware
• Works with ABS and PLA. We are in the process of trying it with nylon based filament.
• 3mm and 1.75 mm filament
• .35mm and .5mm nozzles.
