What print parameters should I use for a successful print?

1. Print on a glass bed heated to 100 C.
2. Use a light layer of Elmer’s disappearing purple glue on the glass for adhesion. Other PVA adhesives have not been as effective.
3. Print with a single layer 10 – 15 mm brim attached to the part.  This is not required for Fluorinar-C™
4. Maximize part surface area in contact with the print bed.
5. Print at 250 C.
7. Layer height can be 0.1 – 0.2 mm.
8. Print speed should be around 20 – 40 mm/s.
9. If the part is small it will help to print in duplicate as the most recent layer on the first part is allowed to cool while the layer on the second part is printing.
10. Keep the cooling fans turned off. Fluorinar-H™ and Fluorinar-C™ like to run hot.
