The fun part of inventing is creating exactly what is desired for a particular application. Inventing is discovering a need and finding a way to fulfill that need. I recently did that sitting here at my computer.
I often pull out the drawer in front of the screen to prop the keyboard at an angle and at a lower position than setting flat on top of the desk surface. It works well in that position and I decided I needed a more reliable system.
I have been wanting to do this since I purchased and assembled this 3D printer. The “standard” method is to use a spool holder that sets next to the printer. It takes up a lot of room and the filament is constantly being pushed back and forth by the “Y” travel of the print head. It works but I never liked that much flexing of the filament.
Kossel Heated Bed
One of my printers is an Anycubic Kossel A6 Delta. It is definitely a D-I-Y (do it yourself) project and a great value for the price. It is available only in kit form. Performance has been very good once I got every detail sorted. It produces very good prints and is fast.
One desirable feature it lacks is a heated bed. The controller (Arduino) has the necessary connections for controlling the heated bed. I ordered the hot plate when I purchased the printer kit. The delivery of the plate is another whole story of its own. I ended up with two of them, paying for one. I will send one back if manufacturer will pay or the shipping. I doubt they will see the value in that…
One of my most rewarding activities is designing jewelry and then creating the design using the process of Lost Wax Casting (LWC). This requires embedding the carved wax design in a plaster like material called “investment” within a metal cylinder called a “flask’.
This flask with the investment (which hardens on its own in about 15 minutes) and embedded wax master are fired in a kiln to 1350 degrees over a 12 hour period.
This visitor came into my workshop, obviously attracted to my 3D printer. I was in the process of testing the operation of the printer after making a repair to a broken strut. I was figuratively trying to, “work out all the bugs.”
