Mechanical Engineering Design Software

The Advantages of 3D Printing in Your Projects

3D printing is a wonderful manufacturing method for both production and prototyping. 3D printing for mechanical engineering projects will allow you to perform many modifications and iterations very quickly and at a low cost, which is very convenient for a prototyping process.

In fact, all you need to do is use 3D modeling software and make all the necessary modifications to improve your 3D model step by step. Using mechanical engineering software allows you to work directly on production.

You can even use different materials to design really complex parts. You can also use metal 3D printing as it will enable you to create really precise, heat-resistant, and well-designed parts. It is used, for example, in the automotive industry, but also for aeronautics and aerospace.

Your company has a lot to offer in additive manufacturing. To do this, modeling and simulating are essential, and you will need 3D CAD software with advanced features.

3D visualization: An essential tool

Some 3D software solutions have amazing rendering tools. Using visualization software or 3D modeling software with great visualization options can help you better understand your project.

In fact, getting a good and accurate overview of a technical project prior to the manufacturing process will allow you to adjust and improve your parts efficiently.  It’s also a good way to correct past errors that you might have missed while designing 3D.

You must determine the best method for designing a concept and presenting it to your customers. 3D visualization is definitely the best way you can find! You can easily modify your model with your own views and customer’s input.

If you’ve been working on mechanical projects, you certainly know that design and analysis are essential. As a result, we recommend that you use software with strong analysis capabilities or another software tool that is entirely dedicated to simulation and analysis, such as ANSYS.

1. Unigraphics NX 

UG (UnigraphicsNX) is a product engineering solution manufactured by Siemens PLM software, which provides users with digital modeling and validation methods for product design and processing.

Unigraphics Nx provides a proven solution for users’ virtual product design and process design requirements.

There is also an abbreviation for UG User Guide and Universal Grammar; It is also called Specter in DOTA.

The development of UG began in 1969 and was developed and implemented based on the C language.

UG NX is a flexible numerical software tool for solving partial differential equations developed using adaptive multigrid methods on two- and three-dimensional unstructured grids.

UG is an interactive CAD/CAM (Computer-Aided Manufacturing and Computer-Aided Design) system.

It has powerful functions and can easily realize the creation of various complex entities and shapes.

But with the development of PC hardware and the rapid development of individual users, applications on PC have achieved rapid development and become a mainstream application of 3D design in the die industry.

Industrial designers can use NX for modelling to quickly create and improve complex product shapes, as well as use advanced rendering and visualisation tools to maximise the aesthetic requirements of a design concept.

2. Computer-Aided Design (CAD) Software

Computer-aided design (CAD) software allows the creation of 3D models of parts and assemblies. CAD software has a drafting component that will enable you to create 2D drawings of your parts that can be manufactured.

CAD tools have direct integration into the FEA (Finite Element Analysis) package so that you can iterate between design and analysis seamlessly.

Examples of 3D CAD software: Unigraphics NX, CATIA, SolidWorks, and Autodesk Inventor.

3. Finite Element Analysis (FEA) Software

Structural analysis can be done with Finite Element Analysis (FEA). Finite element analysis software allows you to analyze stresses and deflections in complex structures. 

A structure is usually drawn in a 3D CAD program, its geometry is created, a mesh is created to divide the structure into elements, forces and constraints are applied, and then the model is solved.

From the solved model, you can interrogate the tension and deflection in the structure.

Examples: NASTRAN and ANSYS.

4. ProE

ProE (PTC Creo or Creo Parametric) is developed by Parametric Technology Corporation and is an engineering design software tool.
