Faceshield slim no strap and stackable

thingiverse

After over 40 days of relentless searching, trial and error, adjustments, and countless setbacks, I finally managed to assemble a G-code model that meets my quality standards, can be easily disassembled, and boasts a smooth finish at the bottom of each piece. The conventional method of leaving a gap between copies didn't work for me. I encountered too many layers that failed to connect or stick properly at the bottom copy (printed in mid-air) or became super-adherent at the bottom layer, causing numerous problems when trying to separate the two pieces. Another major issue was the poor quality of the bottom layer on each copy, with lines featuring significant gaps between them. My wife, a nurse, pointed out that this is unacceptable as it can harbor contaminants that are difficult to clean and sterilize. There were several modifications made, including manual changes to the G-code, but my key breakthrough came from using a "problem" as part of the solution. Do you remember when printing at low temperatures causes layers to split? I applied this principle to just one layer – the first and bottom layer of each copy in the stack. As the printer begins that layer, the hot end drops its temperature to its lowest setting to achieve this goal. Once the layer is complete, it returns to its default temperature. I plan to record a video explaining everything I did and post it on YouTube. Unfortunately, it will be in Portuguese due to time constraints. These quarantine days have been challenging for me (my wife is a nurse, so I'm taking care of our home, daughter, working from home, studying computer engineering, and creating face shields for donation). After using CURA to slice the first three models, I utilized Qlikvire (a BI/dashboards application) to reproduce the layers and manage the gaps effectively.
