For love of ancient architecture I created a ciment model of the Cathedral's Rose, I hope you'll find it inspiring :) !
La rose du transept sud de Notre Dame de Paris
link https://fr.wikipedia.org/wiki/Cath%C3%A9drale_Notre-Dame_de_Paris
Original is made of limestone (CaCO3), so I used the 3DPrinted models to make silicon molds and I used white cement which has a good touching feeling, (and costs only 3 Euro/kg)
To reproduce the effect of stone assembly I cut the rose is different parts assembled in circular pattern.
And to make it stand vertically, I glued magnets on parts so they can be easily placed on a metal panel.
To improve the mechanical properties of ciment, I use plastifier (ref : "Superplastifiant béton et mortier DELTAPRO 300 ml(Code EAN : 3306940056358)
Overall Price:
-3DPrint: a present form DS. Thank you boss.
-silicone model: 70 Euros for 2kg of resin
-magnet: 70 euros (Supermagnet.com, a good site)
-cement 10 Euros
time spend on this:
3Dprint: 1 day
mold: few hours for each
creation of part: about 3 hours per set of 6 parts (because I have 6 molds)
To complete the overall assembly, I needed 12 sets of 6 parts, plus central one
I created one more set to have spare parts in case of accident...
thanks for reading until the end !
