Kinetic bonding– polymers that can’t be chemically bonded easily, can be fused with ultrasonic welding or with high heat. [except with superacids and other complex chemistry.
PolyLactic Acid can be dissolved in Bases like, weak concentrations of Lye and Isopropyl Alcohol … however this mix can cause damage to the nervous system. PC has a pretty good friction/heat fusion like PLA. A better alternative for polycarbonate friction fusion. Nalgene /Poly Carbonate – Methylene Chloride dissolves this along with a long list on MeCl based cocktails. It is best to avoid these polymer solvents It is fairly solvent resistant, but polyurethanes will interact with the polymer. PP will fuse to most of the polyethylenes. Polyurethane based adhesive can bond on a molecular level with polyurethane parts. Gorilla glue is cheap effective and readily available, flooring and wood finishes offer a mixture for finer applications. Ninjaflex is a good example of a flexible polyurethane. Bestine makes a good rubber (with N-Heptane) cement that can bond to both. However latex and many robust rubbers need to be primed or dissolve with N- heptane is a good solvent for latex and most rubbers. “High Impact PolyStyrene”īoth rubber and latex are important for 3D printing allow parts to be designed with flexible joints, gaskets, sleeves etc. Rubber cement can work surprisingly well. ABS will not have this behavior, but it is good to do a test piece before address other styrene polymer eg. This is when the benzene ring breaks open and releases a fair amount of energy. Styrene groups are prone to ring opening. Sidenote: Acetone can often instantaneously dissolve polymers with lots of styrene. More explanation here: ABS plastic & Solvents: 4 good ideas It essentially adds enough chemical energy to allow the polymer to move around an re-order itself for several minutes before the polymer runs out of energy and sets. => Acetone and Methyl Ethyl Ketone will dissolve both ABS and PVC and chemically rebuild the joint in a less ordered manner as the solvents dries. Cyanoacrylate and acrylic based polymers can get good bonding at the molecular level. When to use Super Glue generally if it has the word acrylic in the name. =>Super Glue – water on the surface of the part neutralizes the stabilizer in the super glue and causing to set quickly

When a part takes 15 hours to print and it breaks, a little chemistry can come in handy.
