Simple Spool Bushing V2

December 31, 2013 · admin 3D Printing object

These spool bushings are simple. Use one or two elastic bands to install them on a spool. Nothing else is required. The center hole of the bushing is for a 1/4" smooth rod. It can be easily increased with a drill bit. I have supplied spool bushing of 31, 39 and 52 mm. They fit center holes of 32, 40 and 53 mm respectively. If you need another size, just give me the diameter of the center hole of your spool, and I will upload them. The minimum size is 30 mm.

Unclogging A 3D Print Head

July 29, 2013 · admin 3D Printing

Unclogging a 3D print head is not always an easy task, especially when you lack of the proper tools. They are sometimes hard to find. To unclog a .35mm J-Head fitted for 1.75 mm filament, I am using a strand of a steel cable and a stake flag. The steel cable strand is small and stiff enough to be inserted in the print head by the tip of it. Its diameter is less than .35 mm. The stake flag provides me a rod that I insert in the filament intake. It is stiff and long enough to push it down to the tip of the print head. Home Depot sells both for less than 4 dollars. !unclogging_tools The procedure to unclog the print head is:

Preventing warping when printing 3D ABS objects

February 17, 2013 · admin 3D Printing Prusa Mendel ABS

The biggest issue when printing 3D ABS objects is warping. As an example, this 8 cm x 8 cm bit holder is badly warped. In this example, 5 mm. !](http://www.ctheroux.com/wp-content/uploads/2013/02/dremel-bit-holder-warpage.jpg) Adding disks (1.5 cm x 1 mm) at each corners prevents warping almost completely. These anti-warping disks can be easily added on the plater of Slic3r. The printing end result printing is shown on the picture below. 1 cm x 0.6 cm disks also works fine.

Cannot reach 110 Celsius with a Prusa PCB Heated Bed Mk 1

December 2, 2012 · admin 3D Printing Prusa Mendel

I was not able to reach 110 Celsius with a Prusa PCB Header Bed MK1. My initial installation was with the PCB traces down with a borosilicate glass on top of it. I found out that installing it with the traces up as show below resolved the issue. Nevertheless, the thermistor does not read the real printing area temperature since it is underneath the PCB. There is a 15 Celsius offset and the glass is slightly offsetted. These are small inconveniences. The bed is getting hot pretty fast and is able to reach 110 Celsius.
