The Asiga does have a built in heater... My old one has a hot air heater that can be turned on and is temperature controlled. The price on their material is just way out of line...And you don't know if it will work or not!
I had a sample of the yellow super wax when it first came out. It was easy enough to get good prints from my Asiga printer, but they were so very fragile that they were completely unusable. I tried about 5 times with different models and not one survived gentle handling. I see the colour appears to be pinky red on their website now so it might be a new formula that is more durable??
