Build Preparation Software

Here at 3D Universe, we've spent hundreds of hours testing every available slicing software. Each one of them seems to be good in some areas and lacking in others. The result, we found, is often a workflow that involves several pieces of software and a number of manual steps before a model is ready to 3D print. Simplify3D® gives you everything you need to go from STL (or OBJ) file to a flawless 3D print. This software provides powerful features and intelligent automation to help with each step of the 3D printing workflow.

The Simplify3D Workflow

implify3D is packed with features that help you through each step of the 3D printing workflow.

Import and Repair

Efficiently import 3D model files and analyze the geometry for potential mesh errors that could impact the print. A powerful geometric engine gives you the capacity to handle massive multi-gigabyte files with tens of millions of triangles so that there are no limits to the complexity you can create. Detect and fix common issues including holes, thin walls, or self-intersections that would otherwise create significant problems during printing.

Orient and Arrange

Move your models into the ideal printing position with best-in-class tools for orienting, arranging, and packing. Optimize build efficiency by nesting hundreds of parts on a single build platform, or interactively manipulate a single part to find the perfect orientation for improved print quality. Common issues such as out-of-bounds geometry or incorrectly positioned parts are automatically identified to prevent costly failures.

Support Generation

Patented support structure capabilities offer superior results with an unprecedented level of control. Automatically generate support structures with fine-tuned parameters, or completely customize support location and shape using rapid editing tools. Upon print completion, the sacrificial supports effortlessly separate from the final part with such impressive results, you have to try it to believe it!

Build Customization

The difference between a good print and a great print comes from the level of control you have over the printing process. Simplify3D offers extensive control capabilities far beyond other applications. Our unique process system enables streamlined settings customization for specific parts or regions within a single part. Intelligent software algorithms dynamically adjust common parameters including layer thickness or infill density throughout the print to reduce material usage without compromising our industry-leading build quality.

Slice and Preview

More than a decade of research and development has led to one of the fastest and most capable slicing engines ever designed. Precise machine-specific instructions are generated while incorporating complex real-world physics to optimize the quality and strength of each part. Build files are verified using our advanced Preview Mode which offers an incredibly realistic view of the exact size, speed, and properties of each additive instruction – generating valuable insights about the printing process before it even begins.

Control and Monitor

Simplify3D directly communicates with hundreds of popular 3D printers, allowing you to control and monitor your machines using USB, WiFi, or Ethernet connections. Initiate a new print or track important sensor readings from the comfort of your desktop.
