3D-printed parts
Create functional CAD parts for 3D printing
Tell zCAD. AI what you need to print and what it attaches to. zCAD. AI generates a 3D model where the size you wrote is a number you can check and change. Review the generated model, refine its dimensions if needed, and export it.

01 / The engineering challenge
Why a mesh model may not work as a printed part
A 3D-printed part often needs to do more than look right. It needs to fit an existing profile, align with mounting holes, accommodate fasteners, or connect securely to another component. Mesh models can make it harder to adjust dimensions and connection features precisely.
Mesh model limits
Dimensions may not match
A mesh only approximates the shape and size of a part. A hole intended to be 6mm wide might end up slightly smaller, so an M6 bolt might not fit.
One Change can mean starting over
A mesh has no editable design dimensions. Changing a hole diameter or plate thickness may require modifying the mesh directly or regenerating the model.
Hard to align parts
Matching holes and surfaces between two mesh parts can take extra work.
02 / Connected capabilities
Printable parts that keep their real dimensions
Describe the part's purpose, dimensions, and mounting features. zCAD. AI can generate an initial model from the description, which you can inspect against your requirements and refine in zCAD. Online.

Generate a part from a description
Describe the part's purpose, overall dimensions, and important features to generate an initial CAD model with zCAD. AI.
Define mounting features
Specify hole diameter, spacing, plate thickness, and other dimensions thaty determine how the part connects to existing components.
Inspect the generated geometry
Review the bracket's shape, dimensions, hole positions, and other visible features against your original requirements.
Refine the design
Use prompting in zCAD. AI or continue working in zCAD. Online with the modeling tools available for the model.
03 / From requirement to delivery
From a description to a 3D-printing model
Start with a clear description of the part, generate an initial model, and check the result against your requirements. Refine the geometry where necessary before evaluating the design for its intended use.
Describe the part
In zCAD. AI, describe the part; write what a part does, its overall dimensions, and which features or connections are important.
Generate the initial model
zCAD. AI will generate it from the description, For complex designs, build and verify the main geometry before adding more details.
Review and refine
You can review it, compare the model with the original requriements. You can also open the model in zCAD. Online to continue working with its available modeling features, and make any required adjustments.
Export
From the model output options, Export STL, 3MF or OBJ and you can open it in your slicer.

Before you get started
Frequently Asked Questions
Can I create a 3D-printed part from a text description?
zCAD. AI can generate CAD models from a text description. Include the part's purpose, important dimensions, and connections to give the generation process and useful design context.
Can I create a replacement part for an existing component?
You can describe the replacement part and its required interfaces. Measure the origional component carefully and verify the generated geometry against those measurements before manufacturing.
Can I edit the generated model?
You can open the native AI generated model in zCAD. Online and continue working with the modeling features available for the model.
What should I include in my prompt?
Describe part's function, overall dimensions, mounting points, connection requirements, and any features that must remain fixed. If a critical measurement is unknown, obtain it before relying on the model for manufacturing.
