The amorphous acrylic polymer ABS is opaque and is made up of acrylonitrile butadiene styrene (ABS). This describes how it reacts to heat.
In the case of ABS plastic, thermoplastics become liquid (221 degrees Fahrenheit) at a certain temperature (i.e., they go through a “glass transition”). Heating to their melting point, cooling, and then re-heating won’t result in significant degradation.
A thermoplastic like ABS liquefies instead of burning, which enables easy injection molding and recycling.
Getting a thermoset plastic hot can only be done once (usually during injection molding). During heating, thermoset materials set (like a two-part epoxy), resulting in a change in chemical composition that cannot be reversed. The thermoset plastic would simply burn if heated a second time at a high temperature. Therefore, thermosets do not lend themselves to recycling. In addition, ABS is an amorphous material, which means that it lacks the ordered properties of crystalline solids.

Where Does ABS Come From?
The most commonly used polymerization method for ABS is emulsion (the mixing of multiple products into one). Milk is an emulsified product with a well-known example. A patented process known as continuous mass polymerization is also used to create ABS, although less commonly. ABS is most commonly created through the emulsion process worldwide.
The fact that ABS is a thermoplastic material means it can be recycled easily. Hence, ABS plastic is commonly made from other ABS plastics (i.e. ABS plastic made from ABS). Previously, we covered polypropylene plastic properties, a recyclable plastic.
What is the Purpose of ABS?
Chemically and physically corrosive impacts are not a problem for ABS. It is suitable for injection molding manufacturing processes and 3D printing with FDM machines since it is easy to machine and has a low melting temperature. Also, ABS is relatively cheap (currently, it costs around $1.50 per pound, similar to Polypropylene (“PP”) and Polycarbonate (“PC”). Because ABS plastic melts at a low temperature, it is not commonly used in high heat applications. ABS is therefore used in a wide range of applications across many industries due to its characteristics.
What is the Purpose of ABS?
ABS can be used for a multitude of purposes. Computer keyboard keys, power-tool housing, wall socket covers (often made of PC and ABS), and LEGO toys are among the most widely recognized.
3D Printing and Prototyping: ABS: Advances In 3d Printing And Prototyping:
Because ABS parts are readily available, Creative Mechanisms utilizes Fused Deposition Modeling over other 3D printing methods (such as SLA, SLS, SLM). When transitioning from prototype to production, we can be sure there will not be any significant delays due to material issues due to our FDM machine. The reason it is often used is because it offers a good middle-ground for a host of different applications.
It is easy to machine, sand, glue, and paint ABS. Consequently, it is a very good prototyping material, especially for CR packaging. ABS can also be easily colored, unlike many other plastics. In addition, it gives good cosmetic finishes. This is why enclosures (housing) with different textures or glossy surfaces are often used.
Does ABS Pose A Health Risk?
There are no known adverse effects associated with ABS exposure, since ABS does not contain any known carcinogens. As such, ABS implants are typically not recommended. Find out more about medical prototypes and 3D printing .
How Does ABS Work?
Plastics like ABS are very structurally robust, which is why they are used in things like camera housings, protective housings, and packaging. When you are looking for an inexpensive, tough, stiff plastic that can withstand external impacts, ABS is a good choice.
