Experiment: 3-D Printed Cameo Frames

Since metal jewelry parts can sometimes run out of stock, I wanted to see if I could create 3-D printed parts of a similar quality out of polymer materials. An additional benefit would be making them non-conductive to electricity, meaning easier integration of LED circuits and small coin-cell batteries. I began by making the above […]

The time finally came some months ago to replace the extruder module on my (now-venerable) XYZprinting Da Vinci 1.0 Pro. I can say with certainty that this, above any other possible maintenance technique, drastically improved the quality of all prints. A before-and-after image is displayed below:

It should be noted that, after successfully calibrating the level of the print bed, that simple PVA-based craft glue sticks are more than sufficient to firmly adhere a printed item to the bed until completion. This was originally an issue, as the aluminum surface of the print bed exhibited some oleophobic properties after unboxing.

What all of this means to you is that you can expect better quality printed items from my shop for some time to come. I hope to be of service to you soon.
