What are ABS prototypes

ABS stands for Acrylonitrile Butadiene Styrene a copolymer derived from polymerized styrene together with acrylonitrile in the presence of polybutadiene and therefore can be defined as a thermopolymer.

In use since 1950, it was made with the specific purpose of replacing polystyrene, which has a low impact resistance, to obtain a product that combines the characteristics of a rubbery polymer, such as polybutadiene, and a rigid high mechanical strength, such as polystyrene or acrylonitrile.

Today it is the most commonly used material in manufacturing production. A large part of ABS components are still produced using traditional methods such as injection molding. The increasingly widespread use has been the basis for the success of rapid prototyping and ABS prototypes. This is one of the key factors in the rise of additive manufacturing due to its versatility, aesthetics and dimensional stability.


If previously the use of traditional industrial printers was hampered by inaccessibility due to price and size, now the market is able to offer also competitive 3D printers in terms of price that use materials similar to ABS. We can create prototypes in ABS, or similar, through both additive manufacturing and CNC machining processes

Stereolithography (SLA) is a process capable of creating aesthetic prototypes with excellent surface finish with materials that simulate ABS prototypes. The technical characteristics of the materials used Accura 25Accura ClearVueHTM140ABS 3SP Tough can be found in the technical data sheets. This technology is also optimal for making masters for pre-series from silicone molds.

Sintering (SLS), on the other hand, allows the creation of prototypes with complex geometries, ideal for assembly checks and functional tests with rough finishes.

With MultiJetFusion (MJF) technology it is possible to create nylon prototypes with a lower roughness level and waterproof.

The FDM process creates prototypes in definitive material; the materials we can use with our machines are ASA, TPU, PA66, PA12 Carbon, PC, PC ABS, POM. Prototypes made with this process are suitable for functional testing. The accuracy of the prototypes fluctuates between 0.25 and 0.5 mm and almost always the layers are visible.

CNC mechanical processing is able to ensure a precision that rapid prototyping machines are not able to achieve, but with higher costs related to the processing and management of parts. The list of workable materials is almost unlimited, among which we find ABS.


The benefits associated with the use of prototypes made of ABS reside in the good properties of this material.

In relation to prototyping, the only processes with which it is possible to create models with definitive material are FDM and CNC. The processes maintain the performance of the material, among them they are different in precision and geometry. The choice between the technologies depends on the project needs, especially in relation to how the part was designed, which tests it must undergo and the precision required.


Thanks to its properties, ABS is used to produce many of the everyday objects. In the industrial sector there is no sector that does not use this material from automotive, electronic devices, household appliances, lighting, medical and fitness, military and much more.

To obtain a good finish of the ABS prototypes made in FDM it is necessary to work with a professional machine. The project we created for Promete is testimony to how a model for aesthetic use can also be obtained with FDM printing. To achieve this you need a professional machine and a lot of experience

Why choose Coesum for your ABS prototypes

We have all the industrial and professional technologies for the realization of ABS prototypes.

Our goal in over 20 years of activity has always been to satisfy even the most demanding needs of the manufacturing industry in the best possible way. The drive for continuous improvement is supported by the purchase of latest generation machines and by a continuous investment in materials and process improvement.

The ongoing collaboration with universities and research centers has also led to the development of new patents for the development of materials loaded with graphene and used in 3D printing.
