 ## Variants
 ### PET-CF (Carbon Fiber PET)
+- Almost as easy to print as PETG
+- Extremely stiff
+- Hard to find, expensive
+
+# PVB (Polyvinyl Butyrate)
+- Printing qualities similar to PLA
+- Behaves similar to PETG, weaker but more flexible
+- When exposed to isopropanol alcohol, the layers melt and fuse together, resulting in a very glossy, seamless finish.
+
+# ABS (Acrylonitrile Butadiene Styrene)
+- Very common in consumer injection-molded parts.
