How to repair abs plastic
From which supplier is the plastic? Maybe the compounds that are added to give it color, or other derivatives to reduce costs, make it something similar to ABS in terms of performance, but change its composition in such a way that acetone does not dissolve it.
You can try to dip a piece of filament in pure acetone, it dissolves and becomes like chewing gum, very malleable. Easy to remove with a pin. Another thing is if it is a ‘carbonized’ piece or other material.
I am trying to apply the acetone vapor method to a piece made with ABS from the forocoches joint, and this does not work, it seems to me that the acetone does not dissolve well this plastic (in the videos I’ve seen it says it takes 10 minutes, here I have an hour and not much noticeable).
The thing is that they gave me a gray ABS coil from another store. Well, they have nothing to do… you leave an ABS billet in acetone and in 5 minutes it does not exist… not an hour or two, 5 minutes… the normal thing that is expected of a soluble material in another. And watch out, nothing of threads or deformed mass after a while… it eats it and eats it…
How to melt ABS plastic
ABS has been and is one of the most popular plastics in 3D printing, but with the arrival of new materials that are easier to print or even more resistant its defects are becoming more and more evident: it is difficult to print, it emits an unpleasant smell…
The reasons why ABS is so popular are mainly historical: it is a thermoplastic that was already used in the traditional manufacturing industry when the development of additive manufacturing began and ended up being one of the first 3D printing polymers. It is also a plastic with very good mechanical properties.
Because of its availability and applications, ABS was one of the best positioned thermoplastics to be used as a material at the dawn of 3D printing. It is the primary material for Stratasys printers, the pioneer of FFF 3D printing. When the RepRap movement began publishing the printers from which most of today’s desktop models are derived, ABS was the most popular and readily available 3D printing material, as well as printing better than PLA in those early DIY printer fusers.
What can I glue abs plastic with?
Any analysis of a plastic starts with preliminary tests. In addition to observing characteristics such as solubility, density, softening and melting behavior, heating in a combustion tube (pyrolysis test) and in a flame (flame test) is very important.
Due to the high molecular weight of the polymers it is necessary to chop the sample as finely as possible. If the sample is difficult to cut, it can be frozen with carbonic snow or liquid nitrogen, which will make it glassy, more brittle and easier to cut.
Among the numerous plastic solvents, the most widely used are benzene, tetrahydrofuran, dimethylformamide, diethyl ether, acetone and formic acid. In certain cases, chloroethylene, ethyl acetate, ethanol, methanol, toluene, hydrocarbons and even acids or bases are often used.
Nylon has a high breaking strength, high elasticity and low density. It melts at temperatures of around 260 ºC and softens at 180 ºC. By condensation polymerization, a filamentous, whitish paste is obtained, which becomes elastic and resistant when cooled. It burns smoothly and melts. It is quite stable against chemical agents.
Best glue for abs
ABS plastic (acrylonitrile butadiene styrene) stands out for its high resistance to violent impacts, which is why it is widely used at industrial level. To glue this type of plastic, UV and cyanoacrylate adhesives are ideal, as they improve adhesion durability. Follow the steps below to perform the process properly:Another alternative is to glue ABS plastic using pure acetone. If you want to implement this option, follow the steps below: If you were interested in this article on how to glue plastic, you may be interested in this one on How to bleach plastic, as taking care of your objects is essential to avoid breakage.
