DIY Spinning Wheel Made On a 3D Printer

Peter Kobrin design and 3D printed a spinning wheel for his wife. Spinning wheel was used to make yarn or thread from fiber (like raw wool) which were then woven into fabric. All parts are 3D printed except bearings, hooks and tubing. Parts are made on Prusa I3 in PLA.
It is a great example of how you can use modern technology to recreate a device which was used in centuries past.

He will publish the designs when he is finished with the development.

Lum Continuous Build Belt Platform 3D Printer

Andreas Bastian developed this very interesting 3d printer with continuous build belt platform. Since it is a movable belt you could, in theory, print continuous or infinitely big objects. Yes, it is a DIY project and it is in development so the builds are rough but the concept is innovative.
The name "Lum" is a version of  the word "loom" as the developer is known for his work in textile-like 3d printed structures.

Here is Lum printing its own print bed! First part of a print platform belt is made on different 3d printer and then finished on Lum.

Build guide can be found at for a lower part of it, further build guides will follow:

Disney develops innovative textile 3D printer for soft objects

Disney researchers have developed a completely new 3d printing technology for making soft objects out of textile. They call it "Layered Fabric 3D Printer for Soft Interactive Objects". It works by laser cutting fabric layer form a continuous band and then binding them with heat sensitive glue.

Video of it in action:

Description from the project page:

We present a new type of 3D printer that can form precise, but soft and deformable 3D objects from layers of off-the-shelf fabric. Our printer employs an approach where a sheet of fabric forms each layer of a 3D object. The printer cuts this sheet along the 2D contour of the layer using a laser cutter and then bonds it to previously printed layers using a heat sensitive adhesive. Surrounding fabric in each layer is temporarily retained to provide a removable support structure for layers printed above it. This process is repeated to build up a 3D object layer by layer.

Our printer is capable of automatically feeding two separate fabric types into a single print. This allows specially cut layers of conductive fabric to be embedded in our soft prints. Using this capability we demonstrate 3D models with touch sensing capability built into a soft print in one complete printing process, and a simple LED display making use of a conductive fabric coil for wireless power reception.

Laser Engraving Machine Problems And Solution

Laser Engraving Machine Problems And Solution

The reason of material surface is uneven or too shallow  after engraved by laser engraving machineand Solution:

1. Check the focus distance is ok or not

2. If there is wet paper on the processing material, check if the paper is too much or the water in the paper is too much;
3. Check if the laser tube is ageing
4. Confirm is laser beam path is right
5. The mirror is covered with dust too much
6. Mirror is broken
7. Laser tube head is dirty

Solution For No Laser Given Out

Solution For No Laser Given Out

Solution for No Laser Given OUT
When you use laser engraving machine, you may encountered the issue of no laser given out. There are 3 reasons for no laser given out.  1. Laser tube, 2. Laser power supply, 3. The wire between laser tube and power supply.
Exclusion method: 1. Find another wire to short connect with P and G port. If laser comes out, then it means laser power supply and laser tube can work, the wire connection is with problem.
2 Find laser power supply, pull off its signal terminal, like the below photothen press TEST, connect the cathode clip to the casing to see if there is fire comes out. If there is, then it means that the laser power supply can work, if not, then it means that the power supply is with problem. 
3 Check if the wire between laser power supply and cathode/anode of laser tube, to see if burnt.
4If you press TEST key, it is with laser given out, while no laser given out when engraving, then measure the voltage of Y2 terminal on the control card when the machine is engraving.

  If laser given out normally, voltage between G and IN is 0-5v, H(high level) is with different voltage according to the different power
Voltage is from a few tenth of voltage between G and L  L(low level)              
      If no laser given out, the voltage between G and IN is 0V   L(low level)
       Voltage between G and L is 5V      H(high Level)
Please be sure there is configuration program( file) in the machine, and no fault of power configuration and software.
Pull off signal wire between laser power supply and control card(Y2 terminal on control card), connect the red cathode with casing, then short connect LPG on the power supply, turn on machine, to see if the red cathode can be on fire. If there is fire, then it means power supply can work, it is laser tube with the problem.  
Turn off machine, connect the cathode of laser tube with casing, turn on machine, press TEST key, see if there is fire out from cathode. 
Check Laser power supply instruction:
when the laser power supply is under standby condition, press TEST, LASER lamp is lighting, there is laser from laser tube; if the LASER lamp is not lighting, then laser power supply is broken; if LASER lamp is on, no laser from laser tube, then the laser tube is with problem.
