3D Printing - "It's all about design and quality output. Not how fast the printer can run."
Best invention since sliced bread. Ah... Make that …since sliced .stl’s.
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.”
Delta Construction Error
The accuracy of the Delta printer is very good. It prints with far less “ringing” than my Cartesian printer. Very impressive smoothness of the outer printed shell. The Delta prints much faster than the Cartesian. I have mentioned that before. It’s all about the mass and inertia thing. Less weight moving means faster and smoother printing.
On my Delta, the print surface is 200mm in diameter. The printing area is claimed in writing to be 180mm diameter. That’s 10mm short of the outside edge. The measured maximum round printing area is only 140mm when built following the kit instructions. There is a design problem with the Delta I own.
