The best surfaces to print on with Taulman T-glase

by Roy Worthington

Glass is best for most of the plastics. The reason being glass tends to hold its flatness better than perfboard, and it's also easier to clean too.

When printing with T-glase, we've had good results using two different adhesive products. One is Aqua Net Extra Super Hold hairspray, and the other is Staples Glue Stick (the purple colored stuff). Elmers purple glue stick also works.

The glue stick is a non toxic plastic that seems to bond with most of the plastic filaments that are sold at Octave Systems, and can often yield better results than using a dry bed, i.e. glass, kapton, or painter's tape alone.

The other option, hairspray, should be sprayed with the glass away from the machine as the spray can act as a glue for dust on the internal rails.

So glue is usually your safer bet, but you will have to experiment a bit with how you put it on and how much, as too much can make clumping of glue and won't make for good first layer adhesion. It's easiest to put the glue on when the bed is cool, because if done when warm it will melt the glue and make for too much glue being put down. You should just lightly see the layer of glue on the glass when done applying it. The hairspray however, is much more forgiving when applying it as all you need to do is give the glass a good cover coat.

It's also best to shake or fan the glass to air dry a bit before putting it onto a heated bed.

This method is what we have come to do as our basic setup for most printing. Hhowever, I wanted to quote some stuff from the Taulman3D site as it slightly differs in that they say you can use plain glass and other dry surfaces. We have not tried that ourselves as we tend to use the glue out of habit now since it works so well.

From the Taulman3D website:

"Temperature - Optimum temperature is about 212C to 224C, but will print down to 207C and up to about 235C.

NOTE: A feature of T-glase was to select a polymer that easily sticks to heated acrylic and glass print tables for the smoothest bottom surface possible."

"Shrinkage - Very low shrinkage makes printing large flat surfaces a breeze. And it easily prints to acrylic, glass, Kapton and other platforms."
