Top 10 3D Sculpting Programs – The Best Software for Creating Digital Sculptures for 3D Printing

3D sculpting is a fascinating way to bring characters, monsters, and all kinds of organic shapes to life. While many 3D modeling programs focus on precision, 3D sculpting apps are all about turning a piece of visual clay into a stunning 3D print. This article will show you the 10 best 3D sculpting programs to get the job done!

1. One of the most common questions I get in the comment section is 'What software do you use!?' The simple answer is that I use Autodesk Maya for animation.
2. There has never been more incentive to master 3D modeling programs, and with the rise of independent video games and personal 3D printers, the demand for easy-to-use 3D modeling software has skyrocketed. 3D modeling programs for beginners. By necessity, 3D modeling programs are complex.

In the first part of this blog post, we will focus on sculpting programs. Here, sculpting is the sole purpose of the software and not just a bonus feature. Later on, we will also mention traditional 3D modeling programs that offer basic sculpting modules.

Sculpting Programs

K-3D is a 3D modeling as well as 3D animation software which comes with 3D rendering support. It provides some useful features, such as: 3D Primitives, Different type of objects, boolean modeling operations, Instantiation, etc. Its Linux version also provides feature for collaboration modeling.

1. ZBrush

Without any doubt, ZBrush is the most popular and most powerful digital sculpting program out there. It offers the world's most advanced tools for everyone from art enthusiasts to major film and games studios.

Launched in 1999 as 2.5D modeling software, it is now the go-to solution for 3D sculptors and painters. Jody Garrett, who printed the goat skull that you can see below with ZBrush, calls the software a 'hands-down tour-de-force of digital tools.'

Heads up though: ZBrush comes with a rather steep learning curve and a price of 795 USD. To get a feel for the software without taking any risks you can start ZBrush's 45-day-trial version here. You should also check out our tutorial about how to prepare your ZBrush models for 3D printing here.

2. Mudbox

ZBrush's biggest competitor is Mudbox, which was developed in 2007 and acquired by Autodesk. Mudbox digital painting and sculpting software provides 3D artists with an intuitive and tactile toolset for creating and modifying 3D geometry and textures.

• By: Autodesk
• Price: 10USD/month or 80USD/year

It's hard to say which of these two programs (ZBrush or Mudbox) is really better, but here are some points to consider:

• Mudbox's sculpting style differs somewhat to that of ZBrush and can be considered as more beginner-friendly.
• The main difference between both programs is that ZBrush is much better at generating a base geometry to start modeling with than Mudbox. With Mudbox, you need to use integrations with Maya or 3ds Max to generate a base geometry more easily.
• Overall, ZBrush and Mudbox feature similar sets of tools and brushes. However, ZBrush beats Mudbox in terms of functionality.
• ZBrush is often considered to be superior to Mudbox when it comes to painting the model.
• Mudbox costs 10 USD/month, whereas ZBrush costs 795 USD for a single user license.

Since both ZBrush and Mudbox come as free trial versions, you might want to check them both out first and then choose the program you like most.

3. Meshmixer

If you don't want to jump into the cold water right away, you might want to get started with some free sculpting apps first. Meshmixer is one of the free 3D-sculpting-based CAD programs created by Autodesk – and it is also one of their simpler, more beginner-friendly programs. Meshmixer can be used to intuitively sculpt designs, hollow them out, cut them apart, and combine parts together without wrecking your mesh's internal or external geometry. It's a very cool tool to prepare your design for 3D printing as well.

You can mash, mix, sculpt, stamp or paint your own 3D designs from scratch, or start from over 10,000 models in the 123D Gallery. Our very own mascot (the Piguin; see below), was created in this great program. If you also want to give it a try, be sure to take a look at our extensive Meshmixer beginner's guide.

4. 3D Coat

3D Coat is another interesting digital sculpting program. Its main advantages are its super powerful texturing, UV mapping, and painting tools.

The general 3D modeling part of working with this software is pretty unconventional and differs from the other programs listed here. However, if your number one concern is ‘coating' your sculpt with a great texture, then 3D Coat is your best friend.

This software comes at a price that ranges between 99 and 379 USD depending on which license suits your needs. The 3D printing community of this software is rather small, and so finding good 3D printing tutorials for it is a little more difficult than for the other programs mentioned in this list. To try it, you can simply start with their free 30 days trial version.

5. Sculptris

Sculptris is a free digital sculpting tool, created by Pixologic, the company behind ZBrush. If you're new to the world of digital sculpting, Sculptris is the ideal ground on which to get started. It shows you the very basics of what ZBrush is able to do.

Sculptris provides an excellent gateway into the world of 3D sculpting. Its features are easy to learn, even for people with little or no experience in digital art, yet robust enough for creating detailed base models. Sculptris also lets you import 3D meshes (.obj) for further detailing and modifying.

The only downside of Sculptris is its limited functionality. When you're ready to take your Sculptris creations to the next level for detailing, having a look at ZBrush definitely makes sense.

Further 3D Modeling Programs with Sculpting Capabilities

The programs that we looked at so far are nearly exclusively about sculpting an object. However, several traditional 3D modeling programs also offer sculpting features. So if you already have experience with one of the following programs, you might want to check out their sculpting modules first. Keep in mind that the sculpting functionality of these programs are inferior to those of Mudbox and ZBrush, but it's enough to get a basic job done.

6. Blender

Blender is a very powerful 3D modeling program and a popular choice within the 3D printing community. It has been equipped with a sculpting tool set since 2007, and its workflow is pretty similar to that of ZBrush and Mudbox. Additional bonuses are the sheer number of tutorials and plugins out there as well as the fact that Blender is completely free! However, users continuously complain about the interface and the very steep learning curve!

8. MODO

MODO has an integrated sculpting mode since 2007. The so called 'Painting and Sculpting' function is designed to be simple to use while providing users with a powerful and intuitive toolset that empowers artists to realize their vision with the least amount of strain. MODO comes at around 1,799 USD (30 days free trial here)

• By: Foundry
• Price: from 599USD/year to 1,799USD perpetual license

9. Maya

Maya also extended its 3D sculpting capabilities and added a new set of brushes in 2016. While it does a decent job, many users complain that the workflow is still too buggy and sluggish. Also, Maya comes at 185 USD/month – so unless you already own a Maya license you might want to consider other programs first or try their 30 days free trial.

Free 3d Modeling Programs For Beginners Step By Step

The community of 3D printing and modeling may have become much larger in the past few years, but most 3D models shared online nowadays are limited to a few file formats. One of these file formats is STL. Despite its ubiquity, STL files are notoriously difficult to edit. Should you find yourself with an STL file format that you'd like to tweak and play around with, what software should you use? What exactly is the STL file format, and why is it so important?

What is the STL file format?

STL stands for 'Stereolithography' and is considered one of the simplest 3D file formats. It's also one of the oldest, developed in the 1980s and was originally meant to simplify the transfer of data from 3D CAD models to a 3D printer.

A characteristic of the STL file format, which makes it one of the simpler options, is that it approximates a 3D surface as a triangular mesh. Thus, instead of a truly smooth surface, an STL object is composed of a high number of very small, non-overlapping triangles. This technique is known as tessellation and is considered one of the oldest methods of simplifying a smooth surface in 3D space.

By increasing the number and decreasing the size of the triangles that form the tessellated pattern, the resolution of a 3D file in the STL format can be enhanced. Naturally, a file that holds a higher resolution model will be larger. However, the accuracy at which an STL file can approximate a surface will always be at a lower fidelity compared to file formats that represent 3D surfaces using smooth splines, such as OBJ.

What are the benefits of STL?

The STL file format has been widely used for sharing of models within the 3D printing community. They may have limitations in terms of resolution and fidelity, but so do 3D printers. In fact, STL has become such a preferred file format that most 3D printers and slicer software used nowadays have been designed to work with STL files.

Since STL files are simple and have small file sizes, they are more easily shared and downloaded than other, high-fidelity alternatives. In most cases, users of 3D printers can just download a finished model off of file-sharing websites and print them at home. Beginners to 3D printing typically start this way before developing the skills to come up with their own models.

What are STL editors, and why use them?

While downloading finished models is certainly a quick and convenient way to get into 3D printing, some people may want to edit the features of a model to suit their needs. There could also be circumstances when you only need to print a part of a model. Not all models are perfect, so you may even find yourself needing to repair that model you just downloaded.

There are two different types of STL editing and modeling software. The first is based on CAD and is made for general 3D modeling. This technology has been the standard for industrial and professional 3D modeling and allows for extremely accurate measurement and modeling in 3D space. Since the resolution of 3D printers is limited, CAD software is considered overpowered for use in modeling for 3D printers. Thus, although CAD-based software platforms do an excellent job, editing STL files do not quite utilize the full potential of this type of software.

3D modeling software specially made for 3D printing are called mesh editing software. Instead of precise software representation, a mesh editing software instead reduces these objects into shells with no internal filling. This simplifies the modeling process, although the model can be quickly converted to solid objects right before printing. Within the 3D printing community, mesh editing software is considered more appropriate for STL editing.

The top 5 best free STL editors

1. FreeCAD

FreeCAD is one of the most feature-rich CAD design software platforms. Best of all, the software is open source and completely free. FreeCAD uses parametric modeling principles and has been widely used by both professionals and beginners.

With FreeCAD, you can add features, make measurements, and separate components of an existing STL file. Since FreeCAD was originally meant for mechanical and engineering design, it allows for extremely fine and precise edits. However, it's very difficult to use FreeCAD for sculpting, so smooth surfaces can be challenging.

Even if you don't already have an existing STL file, you can still use FreeCAD to come up with your own 3D sketches and model them in 3D space. It does take some time to get used to the FreeCAD platform and to learn how to use its functions, but it's not so difficult to be inaccessible for beginners. One major flaw of the open source platform of FreeCAD is that it can be full of bugs, although this could be easily remedied by sticking to the latest stable version.

2. Blender

Free 3d Modeling Programs For Beginners Tutorial

Blender is another free 3D printing software that is a little more sophisticated than FreeCAD. It has been touted as a software that can support the whole 3D design pipeline and is best suited for individual designers and small design firms. With a wide suite of excellent features, Blender has been used to for modeling, animation, video rendering, film and visual effects, and 3D simulation.

A huge part of why Blender has been able to extend its range of capabilities is that it's completely community-driven. Users can introduce new features, make minor or major changes to the code, or implement bug fixes. Best of all, Blender is completely free, even if you use it for commercial purposes.

Although modeling is just one of the major functions of Blender, it has a very rich set of features. You can build your own models from 2D sketches or edit an existing STL file. Aside from the usual features, including STL repair, removal and addition of components, and partial masking of models, Blender has much more advanced sculpting capabilities. With twenty different brush types and dynamic sculpting, you can pretty much generate any type of smooth surface. You can grab and pinch areas, flatten sections, inflate and deflate a model, or sculpt the model like clay.

We wouldn't classify Blender as beginner-friendly, but its learning curve is pretty friendly. With so many features, it will take some time before you can unlock the full potential of Blender. As far as 3D printing software go, Blender is one of the most comprehensive.

3. SketchUp

The SketchUp software platform, which used to be owned by Google, is now with Trimble but still retains the user-friendly characteristic for which it became famous for. You have the option of downloading the free SketchUp Make version or upgrading to the paid SketchUp Pro version. The good news is that you can use the free version to edit STL files, but you'll need to make sure to download and install the SketchUp STL plugin first.

The simplicity of SketchUp is its strong suit. It's very easy to learn, and its interface will feel familiar to anyone who's ever used a graphic design program. However, this ease-of-use comes at the price of a limited feature set. The STL editing capabilities of SketchUp are pretty much limited to dragging edges and vertices and adding or deleting individual triangles. It has no built-in STL repair function, but you can still do it manually by using the Solid Inspector tool and correcting any hitches yourself.

Despite the limited features of SketchUp, it remains one of the most widely used 3D design software worldwide. It's highly recommended for beginners. Even people with no 3D modeling experience can learn the fundamentals of SketchUp within a few minutes.

4. MeshLab

MeshLab, as its name implies, is a software platform for editing 3D triangular meshes. It's also open source, which helps give it a rich set of functions and features. If you need modeling software specifically for 3D printing, MeshLab is one of the best options for editing, cleaning, rendering, and texturing mesh-based models.

You will need an existing STL file to make the most use out of MeshLab. It can combine different meshes of a 3D scan, remove parts of an existing, and automatically repair a 3D model. However, it cannot be used to build your own models from scratch. You can also simplify the triangular faces of a model, thereby reducing geometry complexity for easier file sharing.

MeshLab isn't exceptionally user-friendly, but their website has several tutorials that can help get you started. They also have a dedicated community of developers that can provide support if you need bug fixes or if you just have any general questions or clarifications.

5. MeshMixer

In the field of free mesh editing programs, few can equal the quality of MeshMixer. Aside from having a huge set of the necessary mesh editing features, MeshMixer is also very user-friendly. It even has a built-in slicer tool so you can prepare your model for printing and send it directly to your 3D printer via MeshMixer.

The development team behind MeshMixer calls it the 'Swiss Army knife' of 3D meshes. It does have just about everything you need, so we're inclined to agree. You can combine meshes, drag edges and vertices, make measurements, smooth meshes, and even do free-form sculpting. The software comes with a couple of automated features that can help identify problems with your STL file such as holes, misaligned surface, and paper-thin walls.

By combining ease-of-use and an impressive array of features, MeshMixer is considered by many to be the best free mesh editing software. It's only available for Windows and Mac, though, so Linux users will have to look elsewhere.

Final thoughts

If you've gotten into 3D printing, then you probably have dozens to hundreds of STL files lying around in your computer. While printing them as they were modeled originally is fine, the next logical step you need to take is to learn how to edit existing models. This is best done with an STL editor. If you're still a beginner, then we recommend starting with an STL editor that you can download for free.

As you can see from our list of the best free STL editors, being free for use has not hindered these software platforms from having excellent quality. With impressive features and intelligently designed interfaces, it's almost unbelievable that they are free.
