I am a teacher and the pricing on the draftboard would be too expensive for my 400+ students.
I have looked at blick hardboards: https://www.dickblick.com/products/hardboard-panels/?clickTracking=true&wmcp=pla&wmcid=items&wmckw=14945-1066&gclid=EAIaIQobChMIt87ItLKL3wIVmoqzCh1L3wfaEAQYASABEgIoTPD_BwE
Cant get a confirmation that they dont use formaldehyde. The support person said it was laser safe…
I am very paranoid and in a school so i want to make sure that the laser isnt off gassing horrible fumes. But like i said i need a cheaper substrate we can paint thats somewhat sturdy and still safe.
