Imagine What You Could
Accomplish
From job shop floors to aerospace R&D labs, see how MANTIS transforms the way professionals design, program, and manufacture.
Win More Jobs, Faster
A client sends a sketch and needs a 3D model by end of day.
You say:
“Create a parametric model from this sketch: 60×40×10mm bracket with 4 mounting holes, 5mm radius fillets on all edges.”
MANTIS delivers
Complete parametric CAD model in minutes — feature recognition, DFM analysis, tolerance validation, and STEP file ready to share.
Rapid Reverse Engineering
A legacy part needs to be redesigned — no CAD exists, only a physical sample.
You say:
“Replicate this part from the photo: 50mm diameter, 10 teeth, 5mm thick, with chamfered edges.”
MANTIS delivers
MANTIS interprets the image, recreates the parametric geometry, and outputs a clean STEP file — ready for manufacturing.
Iterate at Startup Speed
The prototype needs 3mm fillets added before tomorrow's investor demo.
You say:
“Take last week's motor mount STEP, add 3mm fillets to all sharp edges, then analyze for manufacturability.”
MANTIS delivers
The agent edits parametrically, re-analyzes for thin walls, suggests design improvements, validates tolerances — all in one conversation.
Design Fixtures in Minutes
A new product needs a custom fixture for machining. No time for back-and-forth.
You say:
“Design a fixture to hold a 150×80×30mm part with two locating pins and side clamps. Optimize for manufacturability.”
MANTIS delivers
MANTIS creates the base plate + clamps, runs DFM checks, suggests optimal design features, and generates a complete parametric model.
Finish Projects, Not Tutorials
You've got a weekend to machine custom bike cranks. No time to fight CAM software.
You say:
“Create a 120mm crank arm with 10mm thru holes and rounded edges.”
MANTIS delivers
MANTIS generates the part, recognizes features, warns about thin sections, and provides design recommendations for manufacturability.
Content That Teaches Itself
Your audience wants to see the design process, not just the finished part.
You say:
“Create a modular soft-jaw set for my vise with 4 different profiles. Optimize for manufacturability.”
MANTIS delivers
Record the conversation as content — viewers watch the AI think like a pro engineer in real-time. Educational and entertaining.
Handle Client Revisions Instantly
Client email: "Make the handle 15mm longer and round those corners more."
You say:
“Extend the handle by 15mm while keeping the grip diameter, add 3mm fillets to all external edges.”
MANTIS delivers
MANTIS edits parametrically, re-analyzes DFM, flags any issues, and delivers a revised model — all before your coffee gets cold.
Respond to ECOs in Hours
The prime just sent an engineering change order. "Increase flange thickness by 2mm. We need updated STEP and plan by EOD."
You say:
“Apply the thickness change while preserving all datums and hole locations. Run DFM analysis and generate AS9100-compliant documentation.”
MANTIS delivers
MANTIS edits parametrically, checks for accessibility issues, flags design risks, and produces a complete updated model — same day instead of weeks.
Accelerate Time-to-Clinical
The orthopedic implant prototype needs edge refinements for better tissue clearance.
You say:
“Add 0.5mm chamfer to all edges of the tibial tray. Run DFM analysis for Ti-6Al-4V ELI with 0.005" tolerance.”
MANTIS delivers
MANTIS applies the edit, analyzes for sharp edges, suggests design improvements, and generates a model with detailed documentation for regulatory review.
Ship Tooling On Schedule
Vehicle launch is at risk. The mold insert needs draft angles added and a new electrode designed.
You say:
“Add 1° draft to all vertical walls of this core insert and generate EDM electrode geometry. Give me a high-speed 5-axis plan for H13 tool steel.”
MANTIS delivers
MANTIS edits the core, creates the electrode STEP, analyzes for thin walls, and delivers a plan optimized for surface finish and tool life — same shift.
Learn by Asking Why
You're struggling to understand why your instructor chose adaptive clearing over conventional pocketing.
You say:
“Why does adaptive clearing use less tool load than conventional pocketing? Show me a comparison.”
MANTIS delivers
MANTIS explains in plain language, generates side-by-side plans for the same pocket, shows simulated tool load graphs, and lets you experiment with parameters.
Precision Without Scrap
A collector wants a one-of-one bolt handle. The 17-4 PH stainless blank costs $400. No room for error.
You say:
“Create an ergonomic bolt handle with 3mm radius edges and mirror finish. Generate a 4-axis plan minimizing chatter risk.”
MANTIS delivers
MANTIS generates the model, analyzes for thin sections, suggests helical ramp entry to avoid chatter, and produces a plan with high-feed finishing passes.
The Common Thread? Time Back.
MANTIS doesn't replace skilled machinists — it amplifies them. Less time fighting software. More time making parts.
