Overview
PTC Onshape
Onshape is a professional-grade CAD platform built entirely in the cloud, eliminating the need for expensive hardware or complex installations. You can design complex 3D models, manage your product data, and collaborate with your team in real-time from any web browser or mobile device. Because it uses a single source of truth, you never have to worry about version control issues or overwritten files again.
You can streamline your entire product development lifecycle by using built-in release management and automated workflows. The platform is designed for engineering teams of all sizes, from startups to global enterprises, who need to move faster and work more flexibly. It solves the traditional headaches of file-based CAD by providing a secure, always-accessible environment where your entire team can contribute simultaneously.
PrusaSlicer
PrusaSlicer is a powerful, open-source tool designed to bridge the gap between your 3D models and your physical 3D printer. You can import STL, OBJ, or STEP files and transform them into G-code instructions that your machine understands. The software provides a clean, tiered interface that grows with your experience, offering Simple, Advanced, and Expert modes so you never feel overwhelmed by technical settings while maintaining full control over your prints.
You can optimize your print quality using built-in profiles for hundreds of different printers and filaments, saving you hours of manual calibration. Whether you are a hobbyist printing decorative figures or an engineer producing functional parts, the software helps you solve complex geometry challenges with features like automated wood-grain textures and smart cooling logic. It is completely free to use and works across Windows, macOS, and Linux systems.
Overview
PTC Onshape Features
- Multi-Part Part Studios Design related parts in a single environment to ensure perfect fit and function without managing complex external references.

- Branching and Merging Experiment with new design ideas in isolated branches and merge the best versions back into your main project seamlessly.
- Cloud Simulation Test your assemblies with integrated structural analysis tools that run in the cloud without slowing down your local machine.
- Mobile CAD Editing Create and edit professional 3D models on your phone or tablet using native apps designed for touch-screen precision.
PrusaSlicer Features
- Organic Supports. Generate tree-like structures that use less filament and break away easily without leaving marks on your finished 3D prints.
- Multi-Material Painting. Apply different colors or materials directly onto your 3D model with a virtual brush to create complex, multi-colored objects.
- Variable Layer Height. Smooth out curves by using thinner layers on detailed areas while speeding up vertical walls with thicker layers automatically.
- Measurement Tool. Verify the exact dimensions of your models and check clearances between parts before you commit to a long print job.
- Text Embossing. Add custom text, serial numbers, or logos directly onto your 3D geometry without needing to go back to CAD software.
- G-code Viewer. Inspect every individual layer and toolpath of your print before starting to identify potential issues and save expensive filament.
