Additive Manufacturing or 3D Printing simulation in ABAQUS

The process of building a three-dimensional object from a CAD model or digital 3D model is known as additive manufacturing or 3D printing. In an additive process, an object is made by adding layers of material one after another until the product is made. This process can be done via several methods in which material is joined, deposited, and solidified under computer control. The materials being added together could be made of plastics, liquids or powder grains being fused, etc.

The production of high-quality, high-accuracy parts is made possible by the use of 3D printing simulations, which aid in comprehending and visualizing the intricate thermo-mechanical processes that take place during manufacturing.

When compared to traditional manufacturing methods, this manufacturing process has a number of advantages. These advantages include those related to design, time and cost, amongst others.

Why do we need to simulate 3D printing in Abaqus? Because of the same reasons we do other simulations. Checking if there is any residual stress, checking temperature and thermal conditions, deflection in the model, etc. Moreover, to see if the machine’s settings suit our model’s conditions before printing to avoid unnecessary costs. Conditions like material properties, temperature, etc.

Simulating the 3D printing process is very valuable, because it helps to:

·        Avoid print failures and parts rejected for geometric issues, saving time and reducing overall cost.

·        Evaluate the risk of production and give pointers to mitigate the probability of failure.

·        Understand the physics of the manufacturing process.

You can learn this simulation with two methods: The first method is based on the use of subroutines and Python scripting, and the second method uses ADM plug-in.
