Both are browser-based and user-friendly, making them ideal for students and beginners who want to learn 3D modeling without needing advanced technical skills. They offer intuitive interfaces, essential modeling tools, and easy-to-understand workflows that support hands-on learning.
However, while they serve similar purposes in educational settings, each platform brings unique strengths. This article delves into the similarities and differences between these two programs. If you have been wondering which option to switch to, this article will help you make the right decision. We will begin with the similarities between them, then handle the differences.
Similarities Between SelfCAD and TinkerCAD
Here are the similarities between SelfCAD and TinkerCAD.
1. They Have Web-Based Versions
Both SelfCAD and TinkerCAD run directly in a web browser. This means you can run them from any modern browser without installing any software. This accessibility is especially valuable in educational settings. Classrooms that rely on shared computers or low-power devices, such as Chromebooks, can still use these tools effectively. Since all the heavy processing is handled online, students can focus on learning and creating without worrying about hardware limitations.
2. Beginner-Friendly Interfaces
Both offer a clean, intuitive interface for users with little to no 3D modeling experience. TinkerCAD provides a simple and intuitive interface perfect for beginners and young learners. The tools are laid out clearly, with basic shapes, alignment tools, and grouping options easily accessible from the right-hand panel. The design workspace is open and minimal, which helps you focus on building without distraction. Dragging shapes, resizing objects, or combining them with simple Boolean operations, everything feels straightforward.
TinkerCAD’s colorful, block-like visual style adds to its beginner appeal, making it less intimidating for those new to 3D modeling. SelfCAD, while slightly more advanced, maintains a clean and user-friendly interface that’s still suitable for beginners. The tools are organized logically in the top and side panels, and each tool comes with clear icons and helpful tooltips. SelfCAD provides a smooth workflow where users can transition from basic shape creation to more complex modeling techniques within a unified interface.
3. Geared Toward Education
SelfCAD and TinkerCAD are designed with education in mind and are widely used in schools, STEM programs, and after-school clubs to introduce students to 3D modeling. Their ease of use and low technical requirements make them ideal for classroom environments, where teachers need tools that can quickly engage students without lengthy setup or steep learning curves. Both platforms align well with educational goals in subjects like math, science, and engineering.
4. Use of Primitive Shapes
Both SelfCAD and TinkerCAD contain primitive shapes such as cubes, spheres, cones, and cylinders, which are helpful for the foundation of design. These basic geometric forms are the building blocks for creating more advanced 3D models. You can drag these shapes into the workspace, resize or rotate them, and combine or subtract them to achieve the desired design. This shape-based modeling approach simplifies the design process and makes it easy for beginners to understand how complex structures are formed, while still offering enough flexibility for creative exploration.
6. Free Access Options
TinkerCAD is entirely free, and SelfCAD, on the other hand, comes with a free version that contains almost all the general tools required to create 3D models. If you want to access the other advanced tools, you will need to upgrade to the paid version. This free access model removes financial barriers, especially in educational institutions with tight budgets.
7. Exporting for 3D Printing
Both TinkerCAD and SelfCAD support exporting models in the formats used for 3D printing, like STL and OBJ, though SelfCAD adds a few other formats. Users can easily download their files and send them to slicing software for printing. This is important as the students won’t have to switch to another software to prepare the designs for 3D printing.
Having looked at the similarities above, let’s examine the differences between the two programs.
Differences Between TinkerCAD and SelfCAD
Below are the main differences between SelfCAD and TinkerCAD.
1. TinkerCAD is too Basic as Compared to SelfCAD
It is Only Good for introducing 3D Design; it can't be used for creating advanced 3D models
While this is an advantage, one can easily get started by creating 3D models, especially with simple shapes and fast design turnarounds. However, it falls short when it comes to more advanced projects that require intricate detailing. Students and teachers can only work with basic shapes and modify them to create 3D models, but working on files that require advanced tools like freehand drawing and sketching, or even 3D sculpting, TinkerCAD can’t handle. Kids can use it to get to understand how 3D design works in general; however, as they grow and advance in their skills and now want to tackle more complex, detailed projects, they will have to switch to a different software.
SelfCAD, on the other hand, is not only beginner-friendly, just like TinkerCAD, but it also comes with advanced tools that students can use to create even complex 3D models. Students can start with simple projects and gradually explore more advanced techniques within the same software. This is helpful as the students won't need to switch to a different software in the future when they advance in their skills, and even enter the job market. Some of the advanced tools that SelfCAD comes with are powerful 3D sculpting brushes that are useful for creating organic characters. With those brushes, you have complete control over every design detail.
SelfCAD also includes freehand drawing and sketching tools that make creating 3D models from scratch easy. This offers more creative flexibility compared to shape-only modeling. Students and teachers can draw custom 2D outlines, curves, and paths directly on the workspace, which they can then extrude or modify into 3D models.
They add a layer of artistic control ideal for students, hobbyists, and designers looking to bring unique ideas to life. As students progress in their 3D design skills and take on more complex projects, they can continue using SelfCAD without switching to a different, more advanced software. Unlike TinkerCAD, which is limited to basic modeling and often requires transitioning to professional tools later
2. SelfCAD has an In-built Slicer
For 3D Printing, TinkerCAD allows you to create ready-to-print models and export them in formats like STL, which you will then need to export to a slicer to slice and generate the G-code to send to the 3D printer. For students, it means they will have to install a different slicer and learn how it works besides TinkerCAD to bring their ideas to life, as it doesn’t have its own slicer. While this extra step is manageable for experienced users, it can be challenging for the students. Switching between programs introduces additional learning curves, requiring students to understand different interfaces and workflows just to complete a single print job.
SelfCAD, on the other hand, comes with its own slicer that students can use to slice files and generate G-code on the same platform. After modeling, they simply click the "3D Print" tool, which opens the slicer where they can select their printer, adjust print settings, and preview the slicing process.
After 3D slicing, you can also preview the file to show how it will be 3D printed. You will also get to know the size of the material it will use and the time.
The built-in slicer of SelfCAD not only saves time but also reduces confusion, especially for students who are just getting started. It is compatible with most standard FDM 3D printers and is easy to use. It also runs online, and students don’t need to install any software. It is also free.
3. TinkerCAD Doesn’t Have a Downloaded Version
TinkerCAD is exclusively web-based; you always need an internet connection to open and run the software. While this makes it easily accessible from any device with internet access, it can be limiting in environments with poor connectivity or when offline access is needed. In contrast, SelfCAD offers both an online version and a downloadable desktop application for Windows and Mac. This flexibility allows students to work on their designs online and offline, and both options are synchronized. Whatever they do offline will be reflected online next time the students access the internet, making the software an excellent choice for education, as sometimes their classrooms might have internet issues.
4. SelfCAD Comes With Interactive Tutorials that Makes Learning Easy
SelfCAD comes with interactive tutorials that are built directly into the software. They offer a hands-on, step-by-step learning experience that guides users through the actual modeling process. As you follow a tutorial, SelfCAD highlights the relevant tools in the interface and walks you through each action, such as selecting shapes, modifying dimensions, or applying transformations, within the design workspace itself. These tutorials are not just videos or written guides; they’re fully integrated walkthroughs that respond to your inputs, allowing you to practice techniques in real time while receiving on-screen instructions. See the interactive tutorial in action in the video below, showcasing how to 3D design stairs in SelfCAD.
For the students, this is the best approach to learn 3D designing and the software in general, as it reinforces learning through doing. Teachers can also create interactive tutorials on designing specific designs and share them with the students so they can follow. There are those tailored for beginners, intermediate, and even advanced for those who are already experienced in 3D modeling.
TinkerCAD, while beginner-friendly, relies primarily on basic tutorials and project guides in the form of short videos, text-based lessons, or pre-made projects. These are helpful, especially for younger students, but they don't provide the same level of interactivity as SelfCAD's tutorials. Users must often switch between a tutorial window and the modeling workspace. In contrast, SelfCAD keeps everything within one seamless environment, reducing the need to toggle between tabs and helping learners stay focused.
5. 3D Model Repair Tools Are Available in SelfCAD Which are Missing in TinkerCAD
TinkerCAD doesn’t have tools dedicated to fixing the common errors in 3D prints like non-manifold issues, open vertices, or missing faces, which, when not addressed, can result in problems in 3D printing. SelfCAD, on the other hand, comes with various tools, including the magic fix tool that automatically analyses the mesh and corrects many of the most common problems. This includes merging duplicate vertices, filling small holes, reconnecting open edges, and removing non-manifold geometry like internal faces or over-connected edges.
It's advantageous when working with scanned models or STL files downloaded from repositories like Thingiverse, which often come with hidden geometry issues.
In addition to mesh repair tools, SelfCAD also comes with the Simplify3D tool that allows you to simplify your file and reduce its size. This is especially useful when working with heavy and large files that need to be simplified before being sent for 3D printing or animation. The video below shows how to simplify an STL file in SelfCAD.
While TinkerCAD supports STL editing, it only allows for basic modifications such as resizing, combining shapes, and adding simple geometry. However, SelfCAD offers advanced tools that allow you to make various modifications, such as coloring STL files, as shown below.
You can also remove watermarks in the file, as demonstrated in the video below.
6. TinkerCAD is Not Suitable for Cleaning 3D Scan Data
When 3D scanning, CAD software is required to clean the 3D scans and prepare them for 3D printing. TinkerCAD can’t handle 3D scans, as it doesn’t have the tools for cleaning up the meshes. However, with SelfCAD, you can easily import 3D scans in various file formats and modify them. The video below shows how to fill gaps in a 3D scanned tooth in SelfCAD.
7. TinkerCAD is Limited in the File Formats it Supports for Export
TinkerCAD only supports OBJ, STL, and GLTF files for 3D printing, and SVG for laser cutting. This can be restrictive for users who need more flexibility for advanced workflows. For example, it doesn’t support formats like STEP, DAE, IGES, or 3MF, which are commonly used in engineering, professional 3D printing, and product design. As a result, users may need to rely on additional software to convert files, adding extra steps to their workflow. SelfCAD, on the other hand, supports most of the commonly available 3D file formats.
8. SelfCAD Offers 3D Technology Program for Teachers to Introduce 3D Design to the Classroom, Which TinkerCAD Doesn’t Offer
SelfCAD comes with the 3D Technology Program, which is a comprehensive educational initiative designed to help teachers integrate 3D design and printing into their classrooms, regardless of prior experience. It provides a structured pathway for educators to introduce students to real-world 3D design skills through an easy-to-follow curriculum. The program emphasizes all the aspects of 3D design, like 3D printing, 3D scanning, VR, and other hands-on skills for enhancing STEM education and encouraging innovation among students.
The program provides the teachers with ready-to-use lesson plans, projects, and interactive tutorials that align with educational standards. These resources are designed to help students progress from basic modeling concepts to more complex design challenges.
Additionally, SelfCAD offers dedicated support for educators through training, webinars, and onboarding sessions. This ensures teachers feel confident using the software and delivering lessons effectively. You can check out the 3D technology program to get to know what it all entails.
