Top Layer Perfection

Achieve significantly improved print quality on the top surfaces of your prints with a collection of new features targeting these highly visible regions. Create an unmatched surface finish by applying secondary smoothing passes, unique movement sequences, and intelligent motion planning.

Ironing Smoothing Pass

Perform a secondary finishing pass to smooth top layer imperfections and create a perfectly flat finish.

Monotonic Infill Sequences

Intelligent motion planning creates a more consistent surface finish by carefully controlling the direction and order of infill toolpaths.

Intelligent Anti-Scarring

Reduce unwanted marks and scars on the top surface of your part by leveraging unique retraction and movement behavior.

Complete Top Layer Control

Advanced targeting allows precise customization over top layer properties to achieve perfectly sealed surfaces with the ideal surface finish.

Deeply Integrated WiFi and Ethernet Support

Version 5.1 includes a major upgrade to WiFi and Ethernet communication in Simplify3D. Compatibility has been extended to provide seamless integration with 3D printers powered by Klipper, OctoPrint, and Duet3D electronics. Handheld tablets like the Creality Sonic Pad and FLSUN Speeder Pad are also supported. Once connected to your printer, you can leverage the full power of the Simplify3D Machine Control Panel to upload and manage build files, monitor the status of the printer, and perform maintenance tasks with ease.


Real-Time Build Previews

The Live Preview option in Version 5.1 animates a 3D visual simulation of the print that stays in sync with the current progress of your printer. This real-time view provides unparalleled insights into the exact operations taking place on the machine.

This new functionality in Version 5.1 supports machines connected over USB, WiFi, or Ethernet, providing valuable feedback no matter how you choose to connect to your printer.

Embedded Thumbnail Preview Images

Simplify3D can now embed a thumbnail image of your print directly into exported build files. These images can then be displayed on the printer LCD itself providing useful verification during build setup and printer operation. Simplify3D supports thumbnails with many different formats, resolutions, and settings, enabling compatibility with dozens of popular machines and applications.


With expanded WiFi and Ethernet compatibility, wireless printing and machine monitoring, real-time build previews, and embedded thumbnails, Version 5.1 achieves a new level of integrated simplicity to improve your printing experience!
