The Build Platform
After building the Moai 3D printer platform lowered onto the Vats and it was time to level it by adjusting the four knuts underneath it. This ensured that the build plate would be perfectly aligned, allowing for accurate and precise prints. The instructions provided were clear, but I did have to refer to them a few times as I worked through the process.
I also had to cut out a circle template provided by the manufacturer and place it inside the Vats. This was used to test the functionality of the laser system. To do this, I used the SD cards with the included Yuan test code. The results were impressive, and I was able to see that the laser system was functioning properly.
While working with such a laser, even though it only has a power of 150 M, it is always recommended to use laser safety glasses. This may seem unnecessary for a low-powered laser like this one, but it's still an important precaution to take. As I worked with the laser, I had to be careful not to look directly into its beam.
The First Test Print
Once I realized that I accidentally connected the X galvo to the Wi driver and vice versa, I knew that the printer was properly calibrated. It was now time to attach the remaining two side covers and install the QR software. This involved entering the machine set settings provided by the manufacturer and importing the printing profile.
I then imported a ring test STL file and saved it to slice g code on my SD card. With the QR software installed, I started the first test print. To my surprise, the printer produced a dry print, meaning without the resin in it. This was done to see whether the printer moves like it's supposed to. It did.
To further test the printer, I put on disposable gloves and opened the can of UV resin. The resin had a very neon green unnatural color, but I filled up the vat to 1/5 of its height with the resin. I then started the print. During the printing process, all the motors and lasers seemed to work as they should. However, no traces of solid resin were found.
I tried recalibrating the machine and started a couple more test prints with the Benchmark G-Code of the manufacturer. Unfortunately, this didn't change anything. The laser spots looked a bit unfocused, and changing the position of the laser itself did not fix this problem. Thankfully, however, the manufacturer sent me a new one, which I immediately secured in its rightful place.
Once again, I tried out the ring code without the build platform. This time, without any issues, I noticed that the laser was much brighter and also focused. Therefore, it was no surprise that finally something solid was created with the resin. After reinstalling the build platform and restarting the print, the machine finally worked like it was supposed to and produced the intended object without any problems.
The Final Print
To finalize the print, I got isopropanol, which I filled into one small container. I then brought in another container with plain water and removed the print from the build platform. After dropping it into the isopropanol, I moved it around, cleaned it in the water, and repeated this process three times before letting the print dry and cure for a couple more hours.
While that was happening, I downloaded a model of a whistle and a boat from FY Wars, sliced them, and printed them as well without any problems. Once I treated those objects with isoprenol buff, I was pleasantly surprised with the quality of the print. The boat, in particular, which is like a benchmark for 3D printers, came out way better than I expected.
It's amazing how much detail this SLA 3D printing technique can capture. By comparing the noise level of my Delta printer to the noise level of the SL printer, it's clear which one can be used in a quiet work environment. While I printed the ring model on the Delta printer, which was not a good idea to begin with, it took around 17.5 minutes. In contrast, the SLA printer required around 22.5 minutes for the same task.
