What is AI Design Analysis?
AI Design Analysis (AI DFM) is an automated Design-for-Manufacturability check. The software reads a 3D CAD model and applies the same manufacturing rules a senior engineer would apply — wall thickness and uniformity, draft angle, undercut detection, tool access, hole-to-edge distance, GD&T tolerance risk, material fit, and cost-driving features. SkillsProto's analysis covers seven processes side-by-side: CNC machining, injection molding, sheet metal, 3D printing, vacuum casting, die casting and FRP composites. The AI flags every issue in minutes; a mechanical engineer then verifies the report before it reaches you. The deliverable is a per-part DFM report paired with a priced quote in 24 hours.
Who it's for: design engineers, mechanical engineers and procurement teams in automotive, motorsport, robotics, medical devices, aerospace, consumer electronics and industrial equipment who need fast, free feedback on a CAD file before committing to tooling or production.
AI Design Analysis vs traditional quoting
Most suppliers quote parts without a formal DFM report. SkillsProto runs an automated scan first, so you see manufacturability, cost drivers and lead time together — before the order is placed.
| Criterion | Traditional supplier | SkillsProto AI Design Analysis |
|---|---|---|
| First-response time | 1–5 working days to hear back from a supplier | AI scan in minutes; full DFM report + quote in 24 hours |
| DFM feedback | Depends on the engineer reviewing the file, often after NDA | Standard with every quote — wall thickness, draft, tool access, GD&T, material, cost drivers |
| Cost to get feedback | Often billable engineering hours or hidden in tooling quotes | Free, with or without a placed order |
| Process coverage | Limited to the supplier's installed process (one or two) | All seven SkillsProto processes compared in one report |
| Verification | Engineer-only, no audit trail of rules | AI scan flagged for severity, then engineer-verified before sending |
| Confidentiality | Varies; rarely explicit on website | Mutual NDA on request; restricted-access file storage; no publication without written permission |
What the AI checks
The same physics, tooling and cost rules our engineers apply — encoded and run against your model before a human ever opens the file. Findings arrive ranked by severity, so you fix what matters first.
Wall thickness
Flags sections too thin to mould or too thick to fill, and recommends uniform-wall redesigns that stop sink marks and warpage.
Draft angles & undercuts
Detects vertical faces without draft, side-action features and trapped undercuts before they become tooling surprises.
Tool access & feature depth
Checks hole diameters, pocket depths and cavity reach against standard tooling so features are actually machinable.
Tolerances & GD&T
Compares tight callouts against process capability and highlights the dimensions that drive inspection cost.
Material selection
Suggests substitutes with similar strength, temperature or cosmetic performance at lower cost or shorter lead time.
Cost drivers
Ranks the features that add the most cost — setups, fixturing, secondary operations — with practical simplification options.
Analysis tuned to each process
The AI is not generic. Each process has its own rule set, and where two processes could make the same part, the report compares them head-to-head.
CNC Machining
- Internal corner radii vs. standard cutter sizes
- Deep-cavity and thin-wall machining risk
- Set-up count reduction and 5-axis opportunities
- Thread, counterbore and tolerance feasibility
Injection Molding
- Draft angle and parting-line suggestions
- Gate location, weld lines and flow analysis flags
- Ejector mark risk and rib-to-wall ratios
- Rapid tooling vs. production tooling trade-offs
Sheet Metal
- Bend radius, relief cuts and minimum flange length
- Hole-to-edge and hole-to-bend distances
- K-factor, flat pattern and nesting efficiency
- Hardware insertion and welding access
3D Printing
- Orientation, supports and overhang angles
- Minimum wall and feature size per technology
- SLS/MJF nesting and SLA critical-surface choice
- Vapour smoothing and dyeing outcome preview
How it works
1 · Upload your files
Send STEP, IGES or DXF 3D models plus 2D drawings (PDF/DWG) through the instant quote form. ZIP and RAR archives are accepted; no account is required.
2 · AI scan in minutes
The design engine scores every feature for manufacturability across the processes you select — CNC, injection molding, sheet metal, 3D printing, vacuum casting, die casting or FRP — and ranks findings by severity.
3 · Engineer review
A mechanical engineer verifies each AI finding, adds practical fixes learned from thousands of builds, and rejects any false positives.
4 · DFM report + quote in 24 hours
You receive a per-part DFM report and a priced, engineer-checked quotation within 24 hours on working days — most orders the same day.
Human + AI
No black-box quotes. Every AI report is signed off by a mechanical engineer who has seen the parts come off the machine — so recommendations are practical, not theoretical.
What you receive
Every AI Design Analysis is delivered as a complete package — you do not have to request follow-ups.
Per-part DFM report: issues ranked by severity, with marked-up views where relevant
Priced quotation with quantity breaks — 1 piece to production volumes
Lead-time options per process, including express 3-day shipping
Material and surface-finish alternatives with cost impact
Clear go / no-go recommendation before any money is committed
Industries that use AI Design Analysis
The same rules serve every low-volume manufacturing project we run. The most common users:
Automotive & motorsport
Body panels, brackets, housings and aerodynamic parts that must be light, stiff and cost-controlled — DFM flags draft, wall and tooling risks before tooling spend.
Robotics & automation
Precision machined frames, gearboxes and end-effectors where tight tolerances and GD&T drive cost; the AI highlights the callouts that actually matter for the chosen process.
Medical devices & lab equipment
Patient-contacting and instrument housings in biocompatible metals and plastics; DFM validates material, finish and cleanability choices.
Aerospace & UAV
Lightweight structural parts, brackets and propulsion components where aluminium, titanium and FRP composites are compared on strength-to-weight and cost.
Consumer electronics & IoT
Enclosures, heatsinks and small mechanisms that combine CNC, sheet metal and SLS/MJF; DFM tunes the part for the cheapest process that meets the spec.
Industrial equipment & energy
Drivetrain, fluid-handling and power-conversion parts in metals and engineering plastics; DFM catches undercuts, deep pockets and tolerance over-callouts.

Frequently asked questions
What is AI Design Analysis?
AI Design Analysis (also called AI DFM) is an automated Design-for-Manufacturability check. The software reads your 3D CAD model and applies manufacturing rules — wall thickness, draft angles, tool access, GD&T risk, material fit, cost drivers — to flag issues that would slow down production or raise the price. SkillsProto's AI scan runs in minutes, then a mechanical engineer verifies every finding before the report is sent.
Is the AI Design Analysis really free?
Yes. Upload your files through the instant quote form and the DFM analysis is included free with your quotation — whether or not you place an order.
Which file formats can I upload?
STEP (.step / .stp) and IGES (.igs) for 3D models, DXF / DWG for flat sheet-metal patterns, plus PDF drawings for tolerances and finish callouts. Compressed assemblies (ZIP / RAR) are accepted.
Which manufacturing processes are checked?
The AI compares your part against seven processes: CNC machining, plastic injection molding, sheet metal fabrication, 3D printing (SLA / SLS / MJF / FDM), vacuum casting, die casting and FRP / GRP composites — and recommends the lowest-cost process that meets your spec.
Is my design kept confidential?
Every project is covered by a mutual NDA on request. Files are stored with restricted access and are never shared or published without your written permission.
How fast do I get results?
The AI scan runs in minutes. The engineer-verified DFM report and quotation arrive within 24 hours on working days — most orders the same day.
Do I get a quote at the same time as the DFM report?
Yes. Every DFM report is paired with a priced, engineer-checked quotation including quantity breaks and lead-time options. You do not have to ask for it separately.
Can the AI pick the best process for my part?
Yes. Where two or more processes could make the part, the report compares them on lead time, unit cost and tolerance capability, and recommends the strongest fit. Engineers from each process also weigh in on borderline cases.
