If you are new to 3D Printing, or unsure as to the "What do I need to do differently to use 618" ?  The answer is very simple..  Just load 618 into your printer and Hit "Print"!  618 prints over a wide temperature range and while your current temperature may be low for maximum bonding, you may not need a part that can survive a sledge hammer on your first print.  There are just a few items to note so you eventually get the best from 618's properties.

1.  618 will not print/stick to glass or aluminum print tables.  The best table material for a new user is a flat piece of unfinished poplar wood or blue painters tape. These are at all hobby stores or home depots.  For perfect adhesion, check the information below.

2.  618's bonding is best at a true 245C. 

3.  You may have heard nylon emits fumes.  618 does not emit any fumes for printing.  Actually, there is no odor at all from 618.  You may see what looks like puffs of smoke, but it is actually water vapor or steam.  If you are interested in seeing a full report on extruding Nylon based materials, please check this link as it's an extensive report used by all of industry.
