EYE GLASSES - MODEL B4 - SLA/DLP/LCD

Model Overview & Print Notes

*****THIS FRAME WAS DEVELOPED SPECIALLY FOR RESIN PRINTERS (SLA/DLP/LCD)***** *****It may work with FDM printers, but some details will just not be visible***** This is the model B4 with 153mm width. You will probably need to scale it for matching it to you. You can scale it in X, Y and Z independently, but it could be a problem for mounting the lenses if the scaling of X, Y and Z are too different. I printed with a small Creality Resin Printer and I used a transparent resin with properties similar to ABS and mixed with 20% of flexible resin. Without the flexible resin, the frame is very fragile, but with the flexible resin, finally I have a frame that didn't break after one month. It is very oversized, but the lenses will fit with the other B glasses since you printed them with the same scale factor. You print 3 parts separated, because the hinges would glue during the curing process. To assemble the parts you have to heat the Temples with hot water at around 80°C. Only then you can assemble the temples on the frame, otherwise it could break it!!! For exchanging the lenses you only have to press them from the backside to the front-side and they will detach from the frame. In order to assemble it, then from the front-side to the backside and you mount them. Only remember to heat the frame again with hot water. ## 3D Printing Settings For Resin printers be sure to use ABS-like resin mixed with 20% of flexible resin (high quality ones!!). Then it will be strong enough for wearing them everyday. For FDM Printers, ABS and PETG should work. PLA is not recommended.
