Most digital manufacturers have a solid handle on quoting the primary build — machine time, material, and setup for a CNC job or 3D print. Where margins evaporate is everything that happens after the part comes off the machine: support removal, media blasting, tumbling, dyeing, heat treatment, inspection, packaging, and the labor to move parts between each step.
If you’re still adding a flat percentage or a gut-feel line item for “finishing,” you’re leaving money on the table or losing jobs to competitors who quote tighter. Below is a practical framework to quote post-processing with the same rigor as the primary operation.
Break the workflow into discrete, repeatable steps
Start by mapping every post-processing activity your shop performs. For a typical SLS or MJF job that might look like: depowdering, bead blasting, dyeing, drying, dimensional inspection, and bagging. For CNC: deburring, edge breaking, anodizing prep, CMM inspection, and custom packaging.
Each step gets its own mini-process card with:
- Equipment or station used
- Consumables consumed (media, dye, masking tape, bags)
- Labor category and typical cycle time per part or per batch
- Failure or rework rate from historical data
This turns “finishing” from a black box into a bill of operations you can cost and schedule.
Separate per-part from per-batch costs
Some finishing steps scale with part count (hand sanding each unit), others scale with batch size (one bead-blast cycle handles 50 parts), and some are fixed per order (masking fixtures for anodizing). Tag every step as per-part, per-batch, or per-order.
When a quote request lands, your estimator — or your quoting engine — applies the right math automatically. A 10-part order and a 500-part order of the same geometry will carry vastly different finishing costs per unit, and both will be accurate.
Build labor standards from time studies, not estimates
Run a few timed trials for each finishing operation. Record: setup time, cycle time per part, teardown time, and the number of parts processed. Convert to a labor minute per part at your shop’s fully burdened rate. Update these standards quarterly or whenever you change media, equipment, or staffing.
If you don’t have time-study data yet, start with the most frequent finishing flows. Even three data points beat a wild guess.
Account for yield loss and rework loops
Post-processing is where hidden scrap appears: a part cracks during heat treat, dye uptake is uneven, a critical dimension shifts after blasting. Track first-pass yield for each finishing step. If bead blasting has a 2% rework rate, bake that into the quote as an expected cost, not a surprise.
For high-value parts, add a “contingency per finishing step” line that the customer can see. Transparency builds trust and protects margin.
Link finishing requirements to the incoming RFQ automatically
Modern quoting software can parse STEP files, read PMI annotations, and match customer-specified finishes (e.g., “Ra 1.6 µm, Type II anodize”) to your internal process cards. When the RFQ hits your inbox, the quote draft already includes the correct finishing steps, consumables, and labor — no manual lookup required.
This is where Solvi shines: the instant quoting engine maps customer requirements to your calibrated post-processing workflows, so every quote reflects real shop costs, not a generic markup.
Review and recalibrate monthly
Set a 30-minute calendar invite with your production lead and estimator. Pull the last month’s jobs and compare quoted finishing cost vs. actual. Flag any step where variance exceeds 15%. Adjust the labor standard, consumable rate, or yield factor immediately. Continuous calibration keeps your quotes sharp and your margins predictable.
Conclusion
Post-processing isn’t overhead — it’s a series of manufacturing operations with real time, material, and risk. Treat it that way in your quotes and you’ll win more jobs at better margins.
