3D Printing Software: 6 Best Options OF 2026

3D print design software is a computer program used to create 3D models of objects. These models can be created from scratch or based on existing three-dimensional models. 3D printing software is used by engineers, architects, and product designers to create prototypes and products.

Many different types of 3D print design software are available on the market, and each program has its strengths and weaknesses. But before we look at them, let's look at how you can select the best software for 3D printing.

How Do You Select the Best Software for 3D Printing?

  • Look for a software that is easy to use and has a user-friendly interface. It should be intuitive and straightforward so you can get started with 3D printing quickly and easily.
  • Check if the software can slice your model into G-code. The software can be a 3D slicer or a CAD software with an in-built slicer like SelfCAD.
  • Make sure the software is regularly updated. As new technologies are developed, it’s important to have a software that can take advantage of them.
  • Check the price of the software and make sure it’s within your budget. Some software can be quite expensive, so it’s important to find one that fits your needs and budget.
  • Read online reviews of the software to see what other users think of it. This can be a good way to get an unbiased opinion about the software.
  • Try out the software yourself to see if it’s a good fit for you. The best way to know if a software is right for you is to try it out yourself.
  • Support: Another essential component of any quality 3D printing software program is its support system, which enables users to seek assistance whenever they need it most.
  • Export and Import Options: You can quickly export and import your design between several file types, including STL and OBJ, and others.

6 Best 3D Print Design Software

1. SelfCAD (Overal Best 3D Printing Software of 2026)

SelfCAD is a user-friendly 3D print design software. Both experts and learners can use this 3D modeling software. It is the only 3D design software combining 3D modeling, 3D printing, and artistic and technical tools into one program. It is easy to use and offers several effective freehand drawing, sketching, and simple 3D animation toolsWithout switching to another software, one can use the in-built online slicer to prepare their designs for 3D printing, as shown in the video below.

SelfCAD's slicer is also compatible with the most widely used FDM 3D printers. SelfCAD is a wonderful tool if you are looking for an easy-to-use 3D printer design software in 2023 that runs both online and offline. With SelfCAD, you can also generate realistic 3D renders using its in-built 3D rendering engine. You can add lighting, textures, materials, and colors to your designs easily.

If you have STL files that you would like to modify, you can also do it easily in SelfCAD. For example, you can use the Simplify 3D tool to reduce the number of faces in the STL file before sending it for 3D rendering or animation. You can check the video below to learn how it works.

Also, if the STL file that you have downloaded and imported to the software has a watermark, you can easily remove it  also in SelfCAD  by  following the simple steps described in the video below.

Once you finish editing your STL file, you can export it in most of the common 3D file formats as SelfCAD supports majority of them.

Best For: SelfCAD is perfect for beginners in 3D design because of its user-friendly interface. Using the program's advanced features, experts can also utilize it to create complex designs.

2. Autodesk Fusion 360

With Autodesk Fusion 360, you can create and design the object on the same platform. It is more than simply a 3D modeling tool; it also enables simulation, animation, and 2D drafting. Autodesk Fusion 360 is an online 3D designing software mostly used for product design. It includes machining, collaboration tools, simulation, and industrial and mechanical design all in one package. Fusion 360's capabilities offer a concept-to-production toolkit that makes it quick and simple to explore design concepts. It is the only 3D CAD, CAM, and CAE tool of its type to link your whole product development process into a single cloud-based platform that functions on both Mac and PC.

3. Cura

Cura is an open-source 3D printing software developed by Ultimaker for their 3D printers, although it can be used with most other 3D printers without much difficulty, making it a global standard. Cura allows users to create 3D models from scratch or to import existing models. Once a model is created, Cura can be used to generate a sliced model, which can then be exported as a STL file. This file can then be sent to a 3D printer. Cura also offers a wide range of settings that can be used to customize the printing process, such as adjusting layer height and infill percentage. As a result, Cura is a powerful tool that gives users complete control over their 3D printing experience.

4. Lychee Slicer

Lychee Slicer is an appealing third-party choice for your resin 3D printing needs, offering a vast selection of 3D resin printers and resin profiles. In addition to being one of the most user-friendly, simple, and feature-rich desktop resin printing experiences available, it also happens to have this quality. You can skip all that by pressing the "Magic" button, and Lychee Slicer will take care of everything, but automatic model orientation aids in getting you started with model preparation. Support the works with orientation. Of course, the outcomes can be hit-or-miss, but for simple items, we'll take the time saved by not having to navigate through different model setup dialogues.

5. AstroPrint

AstroPrint is a cloud-based printer hosting system that enables you to slice, monitor analytics, store files in the cloud, and manage many 3D printers. Although there are many paid account tiers available, the free tier provides sufficient functionality for you to easily control your printer or printers remotely.

The basic AstroPrint account is free, but if your printer doesn't already have a Wi-Fi module, you'll need to spend money on hardware to connect it to the internet. Alternatively, if you have a spare Raspberry Pi hanging around, get your hands dirty by configuring AstroBox to use it as a wireless adapter for your machine. You may make prints and transmit them to your printer over a web interface without using any other software, much like OctoPrint (and in fact, there is an AstroPrint plugin for OctoPrint to improve that connection).

6) MeshMixer

MeshMixer is a powerful 3D modeling program that allows users to create and edit 3D models with ease. The program includes a variety of tools for manipulating 3D meshes, as well as a wide range of printing options. MeshMixer has a variety of features that make it a powerful tool for 3D modeling, such as the ability to combine multiple models into one, the ability to add and subtract from models, and the ability to edit individual vertices. 

MeshMixer is also easy to use, with a user-friendly interface that makes it suitable for beginner and experienced users alike. It is also capable of importing and exporting a variety of file formats, making it compatible with many different software programs.
