Main issue: temperature. Is there a material that can sustain a cigarette's temperature for long time? I think not, but one can never be sure so I ask to you experienced producers here on the forum
https://wiki.answers.com/Q/The_temperature_of_a_burning_cigar ette https://www.shapeways.com/materials/glass https://www.shapeways.com/materials/ceramics Both are heatproof to 500C/932F degrees. https://www.shapeways.com/materials/steel It is heatproof to 831C/1528F degrees.
Hey thank you very much! I think I'll go with the steel so that it will be more durable on time, the other two materials are just on the line with temperature and I think on the long time there would be some distortion or clear change in colour etc.
