›
Step 2 of 6
Primary material family?
Select the dominant material. Hybrid assemblies should reflect the structural load-bearing material.
Steel / Stainless / Tool Steel
Carbon, alloy, 300/400 series SS, hardened tool steel, maraging
›
Aluminum / Magnesium Alloys
2xxx, 6xxx, 7xxx series Al; AZ/AM Mg alloys; lightweight structural
›
Titanium / Superalloys
Ti-6Al-4V, Inconel 718, Hastelloy, Waspaloy; high-temp/high-strength
›
Polymers / Thermoplastics
PEEK, Ultem, Nylon, ABS, PC, POM, PTFE, engineering grades
›
Composites / CFRP / GFRP
Carbon fiber, glass fiber, aramid, woven/UD, prepreg, wet layup
›
Ceramics / Advanced Materials
Alumina, SiC, Si₃N₄, zirconia, boron carbide, SiAlON
›
Hybrid / Multi-material
Metal-polymer, clad, overmolded, MMC, insert assemblies
›
Step 3 of 6
Primary design constraint?
Rank what matters most. This drives the weighting algorithm.
Structural Integrity / Strength
Fatigue, tensile, fracture toughness, grain structure, impact
›
Critical Tolerances / Precision
IT grades, GD&T, surface finish Ra, form accuracy, fits
›
Unit Cost / COGS
Tooling amortization, cycle time, material yield, labor content
›
Lifecycle / Durability
Service life, corrosion, wear, creep, thermal cycling, repairability
›
Weight / Mass Reduction
Specific strength, topology optimization, structural efficiency
›
Lead Time / Time to Market
Tooling speed, process qualification time, ramp rate
›
Step 4 of 6
Expected production volume?
Drives tooling investment decisions and cost-per-part crossover analysis.
Prototype / 1–10 units
POC, design validation, no tooling commitment required
›
Low Volume / 10–500 units
Bridge production, specialty parts, pilot builds
›
Mid Volume / 500–10K units
Production intent, hard tooling justified, PPAP submission
›
High Volume / 10K–500K
Mass production, automation, tool life and OEE critical
›
Mass Production / 500K+
Commodity scale, dedicated lines, lean/JIT, statistical process control
›
Step 5 of 6
Part geometric complexity?
Drives mold/tooling feasibility, draft angle requirements, undercut management, and fixturing strategy.
Simple Prismatic / 2.5D
Blocks, plates, simple turned parts; 3-axis machining sufficient
›
Moderate / 3D Features
Ribs, bosses, pockets, compound curves; 4-axis or mold with slides
›
Complex / Multi-axis
Undercuts, deep cavities, thin walls, freeform surfaces; 5-axis required
›
Organic / Topology-Optimized
Lattice, biomorphic, non-machinable geometry; AM-native design
›
Thin-Wall / Sheet / Hollow
T/D ratio <0.1, shells, tubes, formed sheet, pressure vessels
›
Step 6 of 6
Required surface finish?
Surface finish drives secondary operations, post-processing costs, and process compatibility.
As-Processed (Ra 12.5–25 µm)
As-cast, as-forged, raw AM; no secondary finish required
›
Machined Finish (Ra 1.6–3.2 µm)
Standard CNC milling/turning, most injection mold surfaces
›
Fine Ground (Ra 0.4–0.8 µm)
Precision ground, honed bores, bearing surfaces, sealing faces
›
Superfinish / Polished (Ra <0.1 µm)
Lapped, electropolished, mirror-finish, optical, implant-grade
›
Functional Coating Required
Anodize, PVD/CVD, plating, HVOF, parylene, Cerakote, DLC
›
