MatterControl for PC: How to Download & Install on Windows

Introduction

If you want one free program to slice your 3D models, control your 3D printer and manage your prints, MatterControl is the program that does it all. It is a free and open-source all-in-one 3D printing program from MatterHackers, with a slicer, a printer host, a model library and design tools, and it works with most FDM 3D printers. There is no payment, no account and no serial number, and the download from the official MatterHackers store page is the complete program.

This guide explains what MatterControl is, what it can and cannot do, what your PC needs to run it, and how to download and install it from the official website only. You will also get a first-use walkthrough that takes you from installation to a working result in a few minutes. By the end, you should be able to install MatterControl on Windows and use it in a real project.

MatterControl is best for 3D printing, slicing STL files, and controlling a 3D printer from your PC. Because it is free and legitimate, you do not need a cracked copy or an unknown download site. The official website provides the installer, and the free version is a real, permanent tool, not a short trial.

What Is MatterControl?

MatterControl is a free 3D printing program that you install on your Windows PC and use to prepare and print 3D models. In simple terms, it is a program where you load an STL file, slice it into layers for your printer, send it to the printer over USB or Wi-Fi, and watch the print progress on screen: you load a model, choose your printer and settings, slice it, and print. You can also browse a library of printable models and use the built-in design tools to create simple parts.

What makes MatterControl useful is its completeness and its openness. It combines a slicer, a printer host and a model library in one window, so you do not need three separate programs, and it is free and open source under the BSD 2-Clause licence, so it is free forever. It also supports most FDM printers, with profiles for popular models. Two honest notes: the built-in design tools are being replaced by the MatterCAD upgrade, so the design side of the program is changing; and MatterControl is a large program, so it needs a reasonably modern PC and a few hundred megabytes of disk space.

How to Download MatterControl (Official Method)

The only safe place to download MatterControl is the official website. Do not download it from random file mirrors or “free download” portals, because those copies may be outdated or bundled with unwanted software. The official site is the source of truth for the current version.

Official download link: https://www.matterhackers.com/store/l/mattercontrol/sk/MKZGTDW6

On the official MatterHackers store page for MatterControl, download the Windows installer to your Downloads folder. There is no account, serial number or payment involved at any point. If a site asks you to pay for MatterControl, or offers a cracked version of it, leave that site and return to the official MatterHackers page.

Step-by-Step Installation

Follow these steps in order. Take your time with the install location and component choices, because those are the steps that most often cause problems later.

Open the official MatterControl page — Open https://www.matterhackers.com/store/l/mattercontrol/sk/MKZGTDW6 in your browser.
Download the Windows installer — Find the Windows installer and download it to your Downloads folder.
Run the installer — Double-click the downloaded installer file and follow the setup wizard to install MatterControl.
Choose the install location — Accept the default install location, or choose a folder with enough free space.
Finish the installation — Wait for the installer to finish, then close the setup wizard.
Launch MatterControl — Open MatterControl from the Start menu or the desktop shortcut and confirm it opens without an error.
Add your 3D printer — Add your 3D printer in MatterControl, so the program knows which printer to slice for.

Tip: If the installer asks about extra components, keep the default choices unless you know you need something different. Most install problems come from changing a folder or skipping a component.

Is MatterControl Free?

MatterControl is free and open source under the BSD 2-Clause licence, from MatterHackers. You download it from the official MatterHackers store page, install it, and use it without paying and without a time limit. There is no paid version of MatterControl itself. Be aware of two honest limits: the built-in design tools are being replaced by the MatterCAD upgrade, so the design side of the program is changing; and it is a large program, so it needs a reasonably modern PC and a few hundred megabytes of disk space.

That free status is important for this guide. All the steps here use the official download only, and they do not involve cracks, activators or licence keys. If you ever see a site offering a paid or cracked version of the free program, treat it as unsafe and return to the official site.

Frequently Asked Questions

Is MatterControl safe to download?

Yes, when you download it from the official website only. The official installer is the version made by the developer. Avoid third-party sites that bundle extra software or ask for payment for a free program.
