3D Printing is SLOW
So, I took delivery of the 14kg box, and spent a couple of hours assembling the printer. It was partly assembled, as delivered, and if I had known what I was doing the final assembly would have been done in a fraction of the time. The assembly instructions were adequate. The wiring connections were well labelled. The wiring connectors were delicate, and I took care not to bend or break them.
The vertical frame bolts to the base frame, and it is surprisingly rigid. There are 2 Z axis stepper motors, and when not powered up, they can be individually turned. It occurred to me that the horizontal arm which the Z axis motors raise and lower should be exactly parallel to the base, so I placed the machinist’s parallels as shown in the above photo and screwed the horizontal arm down onto the parallels to set the horizontal position. I assume that the Z steppers will move the arm equally. (Hmm… I will check that assumption later.)
Next day, I downloaded the operating software. An older version was supplied with the machine, and the newer version would not work on my old XP Pro Windows computer, so I used the old version.
I spent some time manually levelling the bed, then ran the automatic bed levelling software.
The printed operating instructions are very basic. An Internet connection is assumed, and I did not have one available, so my first printed object was with default settings and the supplied white filament.
Somewhat to my surprise, it worked.
The filename was “dog”. I had no idea whether “dog” was a 3D dog, a picture, or whatever. Neither did I have any idea of its size. After an hour, I had printed a disk about 125mm diameter and 1.1mm thick. Then the disk came off the platten, so I aborted the print.
Today, after getting some advice from Stuart T regarding print adhesion I removed the glass platten cover and applied some special adhesive 3D printer cover. It is called “3M double coated tissue tape 9080A”. Then I printed 2 more items. Neither broke free. in fact they were difficult to remove at the conclusion of the prints.
The next print was a tool which I planned for the 3D printer…..
Not perfect, but too bad at all.
Great, I have a 3D printer too, you get used to the slowness, I’m printing a bracket which will hook my garbage bin to my Segway so I can use the Segway to haul the heavy bins up my steep driveway. I think it will finish printing about 3am tomorrow morning! 🙂
You’ll find yourself thinking of all sorts of uses for it.
My wife gave me a copy of a 70 year old book, “Mechanics in Miniature” by Percival Marshall for Christmas, amazing how far we have come!
