ABS Plastic 3D Printing

Additive Manufacturing Using Augmented Deposition Modeling For ABS Parts

3D Printed Parts of Acrylonitrile Butadiene Styrene [ABS] plastic offer physical properties of your choice for various industrial and medical applications. We utilize three variations of this material: Plain (unenhanced), Carbon filled and Glass filled. At Macfab, we deliver ABS parts for implants, electric plug holders, hardware, jigs and fixtures, and other components by leveraging high-tech industrial 3D Printers.

These parts are light weight, highly resistant to abrasion and capable of achieving geometries not attainable by machining. Our ABS parts are created utilizing Augmented Material Deposition and Fused Deposition Modelling [FDM] techniques.

ABS Thermoplastic Composition

ABS, also called Terpolymer, remains one of the initial plastics to be used in 3D Printing. The material, ABS, is obtained by polymerization of 1/4th acrylonitrile and a little more than ½ of styrene. This polymerization reaction takes place in the presence of 1/5th of polybutadiene.

A specific composition in ABS makes it highly resilient and machinable.

Understanding The Process Of ADM/FDM 3D Printing

3D printing process where a filament of solid thermoplastic material is pushed through a heated nozzle, melting it in the process. The printer deposits the material on a build platform along a predetermined path, where the filament cools and solidifies to form a solid object. In this way, the printer adds multiple layers of thickness ranging from 0.06 mm to 0.25 mm for a final deliverable. Base Material or water soluble materials are used for printing support structures.

Applications of ABS 3D Printing

Medical Implants

Like prototypes, ABS is also good for low-cost medical prosthesis and implants. Prosthetics need to be lightweight for the comfort of amputee and hence ABS is the most suitable one.

Electronics Industry

ABS has very good electrical resistant properties. As a result, it is extensively used in manufacturing electrical enclosures.

Automotive Industry

ABS plastic is used in the automotive industry for jigs and fixtures, and interior customized car components. When reinforced with carbon fibers, even car frames can be developed using ABS in one-off cases.

Benefits of using 3D printed ABS plastic prototypes

Low-Cost Prototyping
ABS has physical properties with high ductility and machinability. This makes it easier to be manufactured and needs no specialty tooling. It reduces the overall manufacturing cost even for one-off prototypes.
Quick Design Verification
Rapid prototyping qualities of ABS facilitate easy, fast, and affordable manufacturing of prototypes for physical testing. You can develop two different design concepts and obtain proofs for each of them, compare, and make informed decisions.
Desirable Physical Properties
ABS polymers are stable with several different chemical compositions. Thus, the proportion of primary elements can be manipulated to get desired properties. For example, two of the three main primary materials of ABS, styrene, and butadiene impart rigidity and impact resistance respectively. By changing the proportion of these two components, one can achieve ABS parts with varying physical properties.
Good Machinability
ABS thermoplastic has a very low melting point and very high heat resistance. Secondly, with a glass transition temperature of 221°F, they are safe to machine. Both these mechanical properties are suitable for easy machining. They support the ability to produce complex and irregular shapes with a fine surface finish.
