        A Complete Guide to 3D Printing Software
Introduction

3D printing software provides instructions and consolidates information to create realistic and real-life 3D models with a 3D printer’s help. 

It is crucial for designing, monitoring, and 3d printing in high-quality. You need to know that a 3D printer without any software is just a machine that doesn’t have any direction. 

If you’re inspired and motivated to create something exciting and 3D print and want to try and know about 3D printing software before investing in a 3D printer, this guide will help you as we’re going to cover most of the software used in 3D printing.

As the 3D printing industry matures, the capabilities of 3D printing software are growing too. When we are talking about 3D printing software, we most often mean 3D modeling software or CAD software; however, it can also refer to software for slicing 3D models, simulation and optimization software, 3D printing management software, quality assurance software, software for editing and repairing STL files, and other programs that we’re going to look at in this article. We’ve made things easier for you by breaking the 3D printing software down in an understandable manner. We’re going, beginning with the 3D modeling software. 

#1 3D Modeling Software

A 3D modeling software is useful in designing the 3D models that are ready for 3D printing. Until recently, most 3D programs available were not optimized for 3D printing. One would only use them for designing general 3D models, but those designs were not ready for 3D printing. 

Software meant for designing for additive manufacturing offers unique opportunities and challenges not found in the traditional design techniques. This is because it’s aimed at the exploration of intricate design features and material reduction. Hence, this requires choosing a relevant tool to help one take advantage of AM’s flexibility.

When it comes to 3D modeling programs, users have three main options: solid, organic, and surface modeling. So the type of options one will have to use and the rendering needed for the final design determines the type of CAD software to be used. However, 3D printing technology and the type of 3D printing material used is of great importance.

Let’s have a look at these three categories. 

i) Solid Modeling

In this option, CAD software is the one most used, and the type of software you will choose will depend on your level of experience and expertise. If you’re a beginner, you need to go for easy-to-use software because 3D modeling can sometimes become challenging and complex. And the industry you work on also will determine the kind to go for. Finally, you will have to choose between an online 3D modeling software and the one that needs installation.

This 3D modeling technique uses a parametric design. A 3D model is defined by replacing the parameters easily. 3D modeling takes form through programming rather than drawing. Like the angle, length, and coordinates, a part’s characteristics can be changed with respect to a point or distance.

This design technique is more rigid than direct modeling, and mechanical and industrial designers use it. The 3D modeling software that uses this technique includes SelfCAD, Fusion 360, Solidworks, FreeCAD, Catia, CREO, Rhino, and AutoCAD. 

ii) Surface Modeling

In surface modeling, the surface of the object is first defined and not the solid interior. This 3D modeling technique is usually used in artistic sectors like in animation and 3D compositing markets. An excellent example of CAD programs used in this category is CATIA, Blender, and Rhinoceros. 

iii) Organic Modeling

Organic modeling allows one to create free form surfaces that have intricate details like sculptures and characters. The most widely used software here is SelfCAD, ZBrush, and Autodesk Mudbox.

There are other categories of 3D modeling software that are worth noting. That is, those that are easy to use and the complex ones. Examples of easy to use software include TinkerCAD, 3D slash, vectary, and SketchUp. There are complex programs that are mostly used by professionals, and these include Cinema 4D, AutoCAD, Solidworks, Inventor, Siemens NX.

We’re not going to look at each of these tools, but we’re going to look at SelfCAD as it can be used in each of the above options and can also be used by beginners and professionals. 

SelfCAD

It’s the only 3D modeling software with combined artistic, technical, Rendering, and 3D printing features all under one program!

SelfCAD is optimized for 3D printing in various ways. There is a Magic fix tool that ensures that the geometry of the model is fixed. An in-built slicer helps you slice your models and generate the G-Code you can send to your 3D printer.

It’s the most affordable professional 3D printing tool used by both beginners and professionals. You can sign up for the free account and use it to try the program, and if it’s okay with you, you can continue subscribing to the premium version.

Websites to Download STL files for 3D printing

Suppose you’re not proficient with CAD software, and you’re not in a position to design your models from scratch. In that case, you can choose to download STL files from website databases, import them to an easy to use program like SelfCAD to customize to fit your requirements. Here are some of the websites you can use to get both free and paid models.

  1. Myminifactory
  2. Thingiverse
  3. Cults3d
  4. GrabCAD
  5. Free3D
  6. Pinshape

This is another excellent 3D printer management software that runs on the cloud. It makes it easier to manage different 3D printers, materials, files, and even slice profiles. It has an integrated database that makes it easier to download whatever one requires effortlessly and wirelessly.

Having looked at the 3d printer management software, we would like to look at the simulation and optimization software.

Simulation and Optimization Software

Simulation and optimization software makes it easier to distribute materials during the design and 3D printing process. For example, these programs help remove materials from a specific part when necessary to function correctly. 

Optimization software makes it easier to respect resistance and load constraints, reducing the entire design’s final weight. This software offers weight savings and complex geometries, therefore increasing performance in industries like automotive and aeronautics. 

Simulation software, on the other hand, helps predict the outcome of the 3d printing process. This software can show how the material will behave when it’s 3D printed too. 

This helps save on time and the general 3d printing cost as errors can easily be detected at an early stage and fixed. Some of the things that can be simulated include temperature, distortion, and post-processing.

The majority of the simulation software is majorly used in metal 3D printing, as it comes with many technical challenges. This software helps analyze the design during the metal 3D printing process and uses the data simulated to plan on the build. Examples of simulation software include:

  1. ANSYS

ANSYS is a simulation company based in the United States. This software predicts the various elements of the 3D printing process hence validating the designs of the parts. ANSYS also provides additive science and additive suite software packages, including thermal analysis and topology optimization. 

The latter is used to understand as well as explain the final properties of the 3D printed part.  

  1. Dassault Systemes Simulia

Excellent simulation software that predicts residual stresses, part distortions, microstructures in composite parts, and metals. It can capture any changes in the material when the design is being 3D printed. The final results of the simulation can then be used to know which material fits which purpose.

  1. Autodesk Netfabb

Netfabb can predict the mechanical and thermal behavior of designs and detect any deformations in a virtual environment. The cloud-based capabilities of Netfabb ultimate and Netfabb premium can do simulation much faster than when in local solvers. 

d) Additive Simufact

Additive Simufact is a cloud-based simulation software developed by Simufact. It has various tools for reproducing key metal additive manufacturing processes and subsequent steps like heat treatment.

It helps users optimize support structures, build orientation, and identify potential issues that can arise on the parts. Addparts’e Simufact can define tolerable deviations and automatically optimize the distortion and generate geometry with less deformation. This helps reduce costly test prints.

Other simulation software available includes Amphyon from Additive works, Digimat-AM from e-Xstream’s, GENOA 3DP from AlphaSTAR Corporations, and also the simulation tool of ESI Additive Manufacturing.

Quality Assurance software

The aim and purpose of this software are to qualify 3D printing for production. The two commonly available ways to achieve this and ensure the part meets the QA requirements are CT scanning and destructive testing. And these methods are usually wasteful, expensive, and time-consuming, and most of the time, they don’t give accurate results.

The best way to ensure that the QA process is effective is through process monitoring. This is where a combination of cameras and sensors is placed in a 3D printer; then, a specific software can then be used to analyze the sensors’ data and the cameras and deliver it in a meaningful and understandable way.

An excellent example of a quality assurance software includes the PrintRite3D from Sigma Labs. It features the modules ANALYTICS, CONTOUR, and INSPECT. Each of these modules has its functionality. For example, the INSPECT module can measure the metal liquid produced when the laser is heated to predict and detect anomalies.

More quality assurance software is expected to be developed in a few years. This is now the new watch in the additive manufacturing world as companies are now aiming to reduce variations and accelerate part validation in the printing process.

Post Processing Software 

Post-processing involves all the activities involved after the 3D printing. They include activities like support and powder removal, surface finishing, sanding, etc. There are three main types of post-processing programs. These includes:

  1. PostProcess

PostProcess has developed intelligent and automated approaches that address the post-printing steps of 3D printing. There is also complimentary chemistry and hardware to solve post-printing challenges specific to materials and the industry’s demands through its software.
