Digital manufacturers increasingly see RFQs that combine CNC-machined aluminum brackets, 3D-printed polymer housings, and laser-cut sheet metal enclosures in a single assembly. These multi-material jobs often carry higher margins, but they also introduce quoting complexity that can stall your response time or erode profit if handled ad hoc.
Below is a repeatable framework used by shops that consistently turn these complex requests into accurate, profitable quotes — fast.
Break the assembly into discrete manufacturing operations
Start by mapping each component to a single primary process: milling, turning, additive, laser cutting, bending, or finishing. Resist the urge to group by material alone; a stainless steel bracket that is milled and a stainless steel cover that is laser cut follow completely different cost structures.
Create a simple table with columns for part number, process, material, machine type, and estimated cycle time. This becomes the backbone of your quote and feeds directly into scheduling later.
Standardize material inputs per process
Each process has distinct material cost drivers. For subtractive work, capture billet dimensions, drop weight, and remnant value. For additive, track powder or filament consumption plus support structure waste. For sheet metal, record nest yield and offcut recovery.
Build a material library tied to process, not just alloy or polymer grade. When a new RFQ arrives, your estimator selects the process first, then the material — automatically pulling the correct cost model.
Allocate setup and programming time per operation
Setup is where multi-material quotes bleed hours. A five-part assembly might need three CAM programs, two fixture setups, and a separate print orientation study. Assign setup time to each operation line item, not to the quote as a whole.
Use historical data: if your 3-axis mill typically needs 45 minutes for a new fixture and your SLM machine needs 30 minutes for recoater calibration, bake those defaults into the quoting engine. Adjust only when part geometry demands it.
Roll post-processing into the line item, not a footnote
Heat treatment, anodizing, tumbling, support removal, and inspection are often scoped per part, not per assembly. Attach each post-process step to the specific operation that requires it. This prevents the common error of applying a blanket finishing cost to parts that never see the anodize tank.
If you outsource any post-process, treat it as a purchased service with its own lead time and markup — visible on the quote line so the customer sees transparency.
Present a unified price with an optional breakdown
Customers want a single number to approve, but procurement teams often need visibility. Deliver a clean summary: total price, lead time, and payment terms. Attach an expandable breakdown showing each operation, material, and post-process cost.
This dual view speeds approval while giving you a defensible cost model if the customer requests changes — remove one operation and the impact is immediately clear.
Close the loop with a digital thread
The quote structure you build here should flow directly into work orders, material requisitions, and scheduling. When the same data model drives quoting and production, you eliminate re-entry errors and gain real-time margin tracking.
Solvi’s quoting engine and MES share a single data model, so the multi-material quote you send today becomes the production plan your floor executes tomorrow. See how it works.
