From your idea to a part
in four steps.
Download the design
or request a print.
02
Review and refine
A first 3D model usually arrives within a few minutes. Inspect it and request changes in chat.
03
Check dimensions and manufacturing
Review the final size and manufacturing checks. Revise the design when needed.
04
Download or order
Download an editable STEP file for CAD and an STL for printing, or review a quote for an eligible print.

AI assisted CAD design
Develop the design. Choose how to make it.
Start with text, a photo, or a sketch. Review the 3D model and request changes in chat. Download editable STEP and STL files or request a quote for an eligible physical print.
STL for printing. STEP for CAD.
Every model downloads as both. STL contains a mesh for printing workflows. STEP opens as an editable solid in CAD software such as Fusion, SolidWorks, Onshape, or FreeCAD. It does not carry a native feature history.
Review before manufacturing.
Confirm dimensions, openings, wall thickness, and connections before ordering. Manufacturing checks determine eligibility for a print; they do not certify mechanical fit, strength, or safety. Review the quote before payment.
What to review before you print
Review dimensions and connections, then request changes in chat. These example conversations show design decisions to discuss before checking manufacturing eligibility.
The wall near this clip broke. Help me revise the design.
Measure the original wall and explain how the clip bends in use. A thicker wall changes stiffness and fit, so review the revised geometry and test a prototype.
Design a cover for my project box. It needs to be 120 mm wide and 80 mm deep.
Check the outside dimensions and how the cover attaches to the box. Include the lip or mounting points in the final size. Review manufacturing limits before ordering.
This bracket needs two holes for M3 screws. The centres are 40 mm apart.
Specify whether the holes are for clearance, threads, or inserts. Review the hole diameter and centre spacing in the model. The process and material affect the final fit.
This adapter needs to slide over a 20 mm square tube.
Measure the tube and describe the fit you need. Leave an appropriate clearance, then test it on the actual tube. Nominal CAD dimensions alone do not guarantee a sliding fit.
Help me add support near the base of this enclosure mounting tab.
Describe the space around the tab and the loads it sees. A rib may change stiffness or interfere with other parts. Inspect the revised model and validate its performance before use.
I have reviewed this design. Can I get a quote for a plastic print?
Confirm the final dimensions and check manufacturing eligibility. Review the available material, quantity, shipping details, and total price before placing an order.
Make the custom part. Then print it.
Describe a replacement part and download its model to print yourself. Parts under 22 cm on every axis can also be ordered as physical prints for an additional charge.

Frequently Asked Questions
Luphra is an AI assisted CAD platform for developing custom parts from text, reference photos, or sketches. Review and refine the 3D design, download editable STEP and STL files, or request a quote for an eligible physical print.
Describe the part or attach a reference image, review the model, and request changes in chat. Confirm the final dimensions and manufacturing requirements before downloading files or placing a print order.
Meshy helps product teams explore concepts as textured 3D meshes from prompts, sketches, or images, then export them for modeling, rendering, or 3D printing. Luphra turns design requirements, text prompts, or reference photos into dimensioned custom parts such as enclosures, brackets, and tube adapters. Refine the CAD design in chat, then download editable STEP solid geometry and an STL for review and printing. For a prompt-to-file workflow, you can take those files into your team's CAD or manufacturing process without ordering a print. When you want the physical part, Luphra adds automated design-for-manufacturing (DFM) checks, a quote, and manufacturing and US delivery for eligible prints. Review the dimensions and test physical fit before use.
Zoo Design Studio combines CAD editing with its conversational Zookeeper agent and supports STEP and STL exports. Luphra brings CAD design, automated design-for-manufacturing (DFM) checks, and physical production and delivery into one workflow. Describe an enclosure, bracket, or adapter, review and refine the model, then download the files or have Luphra manufacture and deliver an eligible print through its production partners. Automated checks cover geometry and printing constraints; they do not certify fit, strength, or safety. Standard print orders support PLA or PETG parts under 220 mm on every side and ship within the US. Review the quote before ordering; manufacturing is billed separately.
Xometry's online quoting workflow starts with a CAD file you upload and offers a broad range of manufacturing processes and materials. Luphra lets you start before that file exists: describe or show the part, refine the CAD design in chat, review dimensions and manufacturing checks, then download editable STEP and STL files or request an eligible PLA or PETG print. Design, review, and ordering stay in one workflow; physical fit still needs testing.
You can explore custom hardware such as covers, knobs, clips, brackets, adapters, and enclosures. Suitability depends on the geometry, material, and intended use. Review generated designs and test functional parts before relying on them.
Yes. Attach a reference image and describe the part. Photos do not establish exact scale or hidden geometry, so add measured dimensions for features that need to fit.
Every finished model downloads as a STEP file and an STL file. Open the STEP file in CAD software such as Fusion, SolidWorks, Onshape, or FreeCAD and edit the solid geometry there. Use the STL for slicing and 3D printing. You can also request revisions in chat. STEP carries the solid geometry, not the sketch constraints or feature history, so edits in your CAD tool start from the solid.
A simple bracket, enclosure, or adapter usually reaches a reviewable 3D model within a few minutes of sending the description. Luphra may first ask for missing dimensions, and complex parts or revisions can take longer. Review the model before you download or order it.
You can start with a description and the dimensions you know. Review the model before manufacturing, and get engineering help when fit, loads, or safety require it.
Yes. Luphra is in beta. Sign in to develop a design, preview it in 3D, download available files, or request a print quote.
Fit is not guaranteed. A printability check does not validate the part against your assembly. Measure the connections, review the design, and test a prototype before use.
Plus is $0 for 30 days free (card required), then $49 USD per month with 30 CAD runs. Ultra is $119 USD per month with 100 CAD runs. Chat is unlimited; each build uses one run. A subscription is required to create designs. Physical printing is billed separately.
