Altair® Sulis™

Rapidly design complex parts for additive manufacturing (AM)

Sulis is a design for additive manufacturing (DfAM) solution that enables engineers to create complex lattice structures and fluid flow channels for use across a range of industries, including aerospace, automotive, medical, and industrial machinery. It’s a 3D printing design software tool that gives users unmatched customization tools and manufacturing checks.

With a custom geometry kernel for tubes and an implicit design kernel for latticing, the highly automated AM manufacturing design software features and easy drag-and-drop functionality provides a real-time DfAM approach, enabling fast geometry creation for additive manufacturing (AM).

Since Sulis is a CAD tool created specifically for AM, engineers can design parts that truly leverage the freedom of AM, unlocking the power of implicit geometry and reducing the risk of costly 3D printing failures.

Why Sulis?


Create Advanced Geometries

Sulis's AM design software has a simple interface that empowers designers to rapidly generate new concepts that are optimized specifically for AM. With one-click lattice creation, you can quickly add lightweight lattice structures to models and fine-tune their properties. You can also easily create 3D spline geometry and define or change concept layout in real-time. The custom scripts and novel workflows take you far beyond traditional CAD, driving innovation and accelerating your design cycle.


Printable Components in Minutes

Sulis is a 3D printing design software like no other that lets users predict and remove future AM complications. The built-in manufacturability analysis and compensation tools reduce manufacturing complications and failures, letting you print with confidence. Sulis's interface is also simple to use, which shortens the time it takes to get from design to print. You can generate new concepts that are optimized for AM and have printable geometry ready not in days, but in minutes.


Simple Implicit Geometry

Sulis is one of the simplest 3D printing software solutions for generating high-resolution, complex lattice structures for AM. With a specialized implicit design kernel and advanced customization tools, design engineers find Sulis ideal for energy absorption, heat transfer, filtration and other applications. Sulis's implicit modelling approach enables designers to create complex geometry at any scale which makes the design of components using metamaterials possible among other benefits.

Key Features

One-click Lattice Creation

Choose between surface, strut, stochastic and planar lattices, or combine different lattice types in a single part. Also, choose between multiple coordinate systems to ensure lattices fit seamlessly within your CAD and AM design software models.

Tailor the Properties of Lattice Structures

Tailor the properties of your lattice structures by grading cell size and density across multiple axes. You can also reduce material usage and printing times by converting to a model with the desired shell thickness and interior lightweight lattice structure.

Range of Unit Cell Types

Select from a huge database of commonly used unit cells or define your own custom strut-based unit cells. This creates a new range of design opportunities, from tailoring mechanical properties to creating a variety of metamaterials – including auxetic structures.

Real-time Visual Feedback on Flow Paths

Dynamically edit patterned objects to create multiple spline objects while receiving real-time feedback on your design. Also, you can edit complex fluid networks in real-time using the click-and-drag tools.

Easy Conformal Geometry

Conform geometry over complex surfaces to increase packing efficiency, minimise material usage, or improve heat transfer between surfaces. You can also optimise the fluid network layout, routing, and interfacing components to be more compact and manufacturable.

Self-supporting Fluid Channels

Automatically analyse and compensate fluid channels to be self-supporting. This removes the need for painful internal support post-processing.
