How to Convert 3MF to STL for 3D Printing using reaConverter

How to Convert 3MF to STL for 3D Printing using reaConverter

The 3MF (3D Manufacturing Format) has become one of the most modern and flexible formats in additive manufacturing. It can store not only the geometric mesh of your model, but also materials, textures, colors, print parameters, and metadata – all neatly packaged inside a compressed ZIP-based container.

However, despite its advantages, many 3D printers and slicing tools still rely on the STL format. STL remains the simplest and most widely supported geometry-only standard in 3D printing. For this reason, converting 3MF to STL is a frequent and necessary step in many production and prototyping workflows.

In this tutorial, we’ll look at how reaConverter processes 3MF files, how to control the conversion quality using Level of Detail, and how to export clean STL files ready for slicing.

It’s a built-in automation tool designed for non-technical users who regularly handle dozens or thousands of images, or documents.

Right-Click Conversion with Windows 11 Context Menu Integration

by

A step-by-step guide to turning reaConverter Pro into your fastest “File-Conversion-On-Demand” button.

Right-click conversion

Why bother with the context menu?

Windows 11 slimmed its right-click (context) menu and hides many third-party options behind “Show more options.” That second click slows you down — especially when you’re batching dozens of images. reaConverter Pro 8 solves the problem by wiring itself directly into the modern Windows 11 menu, so one click launches an instant conversion using your favorite preset.

If you still see the older two-step experience, Microsoft’s design simply tucks extra items under the submenu; you can always click Show more options to reveal them.

How to Convert Scanned JPEG with Text to Searchable PDF Document

by

JPEG is probably the most popular extension for storing and transferring images. Many users prefer this format for sending photographs by email or uploading them on social networks. The reasons are obvious: JPEG can be opened with even the most basic image viewer, provides small size and decent image quality.

The format is also used as output extension by many scanning and faxing devices. Using JPEG you can get a quick and small digital copy of a document. As this is a raster format, however, what you get is an image reproduction of the document. Not an actual text. This means scanned JPEG cannot be searched or edited. Depending on your area of work, this can be a considerable problem. For example, if you scan a certificate or an invoice that you need to make quick corrections to, the JPEG format will not be of much help.
