• How It Should Be Used (The 80/20 DfAM Rule): In Generating TPMS Gyroid Fluid Cores in Rhino Grasshopper MCP & Printing in GLUCK G40-JG High-Temp and Clear SLA, treating raw AI outputs or unverified scripts as one-click production files causes non-manifold slicing failures, suction-cup blowouts, and paint-thickness (40–60μm) assembly binding. Leverage AI/MCP for rapid 80% form and script iteration, and lock the critical 20% through watertight repair, B-Rep datums, and GLUCK’s 6-Gate engineer qualification.
• Future Direction (AI-Native Manufacturing 2026–2030): Hardware development is converging on AI-Native Manufacturing—where teams generate and validate designs via AI and MCP (Blender, Rhino, Fusion 360 MCP) and connect directly to GLUCK’s 48-machine industrial SLA smart factory (up to 1,000×800×600mm monolithic beds, in-house Class-A painting, and Creaform 3D scan QA) for tooling-free production.
• GLUCK Custom Engineer Quoting Policy (No Fixed Unit-Price Tables or Auto-Calculators): Because industrial 3D printing prototype and bridge-production costs depend completely on industry sector, application, part geometry, mesh remediation scope, cosmetic finishing tier (Zone A/B masking), order quantity, and delivery schedule, GLUCK does not expose generic unit-price tables or automated calculators—providing a tailored 1:1 engineer-led evaluation from your 3D CAD (STEP/STL).

Core Engineering Rule: Before scaling any AI- or MCP-generated 3D model into physical prototypes or 100–1,000+ unit bridge production, verify all 6 physical qualification gates:

1. Gate 1 (Manifold Integrity & True Relief Depth): Eliminate non-manifold edges, inverted normals, and internal floating shells, and displace 2D normal-map details into at least 0.30–0.45 mm of real 3D geometry.
2. Gate 2 (Wall Thickness, Drain Vents & TDS Alignment): Maintain 2.0–2.5 mm minimum walls with dual Ø3.5 mm+ washout drain holes on hollow parts, and cross-check website summary codes (G20-BR, G40-JG, White, Clear) against published English PDF TDS documents (G10-BR.pdf, G10-WH.pdf, G40-GW.pdf, G40-JG.pdf).
3. Gate 3 (Thermal, UV & Chemical Environment Protection): Specify thermal-review G40-JG (HDT 80°C @66psi test metric) near warm components, and apply opaque primer plus 2K polyurethane topcoats for outdoor UV or clinical 70% IPA wiping.
4. Gate 4 (Fastener Preload & Boss Reinforcement): Avoid direct resin tapping; integrate heat-set knurled brass inserts and metal compression limiters to prevent polymer creep relaxation and boss splitting.
5. Gate 5 (Cosmetic Zone A Painting vs. Zone B Mating Masking): Keep exterior Class-A faces (Zone A) free of supports for wet sanding and urethane painting, while masking mating step-lips, pins, and bosses (Zone B) with +0.15–0.25 mm clearance.
6. Gate 6 (Mandatory 1–5 Unit First-Article Validation): Validate physical fit, finish, and functional performance on 1–5 First Article samples prior to releasing 100+ unit parallel batch production.

Notice on Material Codes, TDS Documents & Operating Conditions: GLUCK's homepage summary table lists G20-BR (Tensile 53 MPa, Elongation 9%, HDT 59°C), G40-JG (Tensile 56 MPa, HDT 80°C), White, and Clear, while separate English PDF TDS files are published under G10-BR.pdf (Tensile 40–58 MPa, Elongation 7–12%, HDT 55–68°C @66psi), G10-WH.pdf (Tensile 49 MPa, HDT 56°C @66psi), G40-GW.pdf (Tensile 54 MPa, HDT 59°C @66psi), and G40-JG.pdf (Tensile 44–56 MPa, Flexural Modulus 2,675–2,765 MPa, HDT 80–93°C @66psi). Correspondence between homepage summary codes (such as G20-BR or White) and separate PDF filenames (such as G10-BR or G10-WH), as well as the exact resin lot, manufacturer grade, and active TDS revision, must be confirmed during pre-order consultation and should not be assumed identical without confirmation. HDT values are standard test metrics (@66psi), not continuous operating guarantees; orders of 100+ identical parts require first-article prototype validation.

Q1. How do you size TPMS Gyroid wall thickness (≥1.2mm) and channel pitch (≥4.0mm) in Grasshopper so IPA wash fluid flushes 100% cleanly?
A1. When executing Generating TPMS Gyroid Fluid Cores in Rhino Grasshopper MCP & Printing in GLUCK G40-JG High-Temp and Clear SLA, use Rhino 8 MCP (RhinoCommon + Grasshopper + ShrinkWrap + QuadRemesh -> SubD -> NURBS) + GLUCK 1,000mm SLA and rg.Mesh.ShrinkWrap (TargetEdgeLength = 0.25 mm) to convert fragmented AI meshes into a 100% closed watertight solid—or convert via QuadRemesh -> SubD -> ToBrep into STEP (AP214)—and route the build to GLUCK's up to 1,000×800×600 mm monolithic large-format SLA fleet.

Q2. Why does GLUCK provide custom engineer-led quotes rather than exposing fixed unit-price tables or auto-calculators?
A2. Industrial 3D printing prototype and bridge-production economics vary completely by industry sector (robotics, mobility, medical, collectibles, exhibition art, luxury packaging), part geometry, mesh remediation complexity, cosmetic finishing tier (Zone A painting and Zone B masking), order quantity, and delivery schedule. Rather than exposing generic price tables, GLUCK engineers review your 3D CAD (STEP/STL) to optimize build-tray nesting and process routing.

Q3. How does GLUCK protect confidential AI/CAD files and maintain lot-to-lot repeatability across repeat orders?
A3. Operating 48 industrial SLA machines under one roof in Paju, South Korea eliminates multi-vendor broker network leaks. Under GLUCK's Two-Tier Data Retention Policy, standard one-off RFQ files are automatically purged after 6 months (or deleted immediately upon NDA security request), while contracted repeat-production programs lock approved Part Number (P/N) and Revision (Rev. A/B/C) build recipes.
