“Small batch” sounds small. People assume it means slow, manual, one-at-a-time production that can’t keep up with real demand. That’s not how it works.
We regularly produce 200+ identical parts per week across multiple printers running simultaneously. Here’s what that production flow actually looks like, from file receipt to shipped boxes.
Day 0: Planning and Setup
Before a single printer starts, we plan the production run.
Nesting: Parts are arranged on build plates to maximize machine utilization. A single build plate might hold 8, 12, or 20+ parts depending on size. Efficient nesting means fewer print runs, lower machine time per unit, and faster throughput.
Print scheduling: We assign parts across multiple printers based on material, build plate size, and current machine availability. A 200-unit order isn’t one printer running for five days — it’s 4-6 printers running in parallel, each producing a batch.
Material preparation: Same material lot allocated for the entire run. This ensures color and mechanical consistency across all 200 parts. If a job requires 4kg of nylon, we verify we have 4kg from the same batch before starting.
Settings lockdown: Print parameters — temperature, speed, layer height, infill pattern — are set once and locked for the entire run. Every part prints with identical settings. No mid-run adjustments, no “let me try something different on the next batch.”
Days 1-3: Printing
This is where parallelization matters.
Example breakdown for 200 mounting brackets (80x60x25mm, nylon):
- Parts per build plate: 12
- Total build plates needed: 17
- Print time per plate: 8-10 hours
- Printers running simultaneously: 5
- Total calendar time for printing: ~30-34 hours across 3 days
Printers run overnight. The first batch starts Monday morning, and by Wednesday evening, all 200 parts are off the machines.
For smaller parts, the math gets even better. We’ve nested 40+ small clips on a single plate, printing 200 units in five build runs total.
Monitoring: Every printer is monitored. If a print fails at hour 2 of a 10-hour run, we catch it, restart the plate, and don’t lose a full day. Failed plates get rescheduled into the same production window.
Days 3-4: Post-Processing
Raw parts off the printer aren’t finished parts. Post-processing is where production parts diverge from hobby prints.
Support removal: Any support structures are removed — mechanically, not by tearing. Clean breaks at the support interface, no gouges or surface damage.
Surface finishing: Depends on requirements. Options include:
- Sanding critical surfaces to remove layer lines
- Bead blasting for a uniform matte texture
- Vapor smoothing for a glossy finish (specific materials)
- Tumble finishing for batch processing of small parts
Hardware insertion: If the design includes threaded inserts, heat-set inserts, magnets, or press-fit hardware, those go in during post-processing. We use calibrated insertion tools, not soldering irons.
Assembly: Multi-component parts get assembled, bonded, or fastened during this phase. If you’re shipping a product with three printed sub-components, we assemble them so you receive finished units.
Post-processing is labor — it’s hands on every part. This is built into the per-unit quote, not billed as a surprise after printing.
Day 4-5: Quality Control
Every part gets inspected. Not a sample — every unit.
Visual inspection: Surface defects, layer adhesion issues, warping, stringing, incomplete features. Any part that doesn’t meet visual standards is reprinted, not shipped.
Dimensional verification: Critical dimensions are checked with calipers or pin gauges. If the part has mating surfaces, tolerances on those surfaces are verified against the CAD model.
For critical applications, we can provide dimensional inspection reports — measured values for specified features on every unit or on a sampling basis, depending on your requirements.
The reprint buffer: We plan for a 3-5% reprint rate. If 4 of 200 parts don’t pass QC, replacements are already scheduled into the production window. We don’t ship 196 parts and tell you the other 4 are coming later.
Day 5: Packaging and Shipping
Parts are packaged for protection, not for show (unless you need retail packaging — we can do that too).
Standard packaging: Individual bagging, foam separation, corrugated boxes. Parts arrive without scratches, chips, or damage.
Labeling: Part numbers, batch numbers, material identification, quantity. Whatever your receiving department needs for tracking and inventory.
Shipping options:
- Standard ground: 3-5 business days across Canada
- Expedited: 1-2 business days
- Direct to your customer: we can ship individual units or kits directly to end users with your branding
Real Numbers: A 200-Unit Production Run
Here’s an actual production timeline for a recent 200-unit bracket order in nylon:
| Phase | Duration | Status |
|---|---|---|
| File review + production planning | 4 hours | Day 0 |
| Printing (5 printers parallel) | 30 hours | Days 1-3 |
| Post-processing (support removal, insert installation) | 12 hours | Days 3-4 |
| QC inspection (200 units) | 6 hours | Day 4 |
| Reprint failed units (7 parts) | 4 hours | Day 4 |
| Packaging and labeling | 3 hours | Day 5 |
| Ship | — | Day 5 |
Total elapsed time: 5 business days. Parts delivered the following week.
Per-unit cost for this specific job: $32 (including material, printing, post-processing, QC, and packaging). Total order cost: $6,400 for 200 production-quality nylon brackets.
When Small-Batch Makes Sense
Small-batch 3D printing production is the right call when:
Bridge production. Your injection molds are in fabrication and you need product to sell now. Print 200-500 units to cover the gap. When the molds arrive, switch over.
Limited editions. Products intentionally produced in small quantities — collector items, seasonal variants, special collaborations. No tooling investment for a run you’ll never repeat.
Custom and personalized products. Each unit is slightly different — custom dimensions, personalized features, variant configurations. Every unit can be unique with no changeover cost.
Market testing. Launch with 200 units to prove demand before committing to high-volume tooling. If it sells, scale up. If it doesn’t, you’ve invested $5,000-8,000 instead of $20,000-50,000.
Aftermarket and replacement parts. Low-volume parts that need to be available but don’t justify keeping injection-molded inventory. Print on demand as orders come in.
Scaling Up
200 units per week is not our ceiling. The same parallel-printer approach scales:
- 500 units/week: More printers, same workflow
- 1,000 units/week: Multiple shifts, expanded post-processing team
- 2,000+ units/week: Dedicated production cell with automated build plate handling
The per-unit cost stays relatively flat as volume increases because nesting efficiency improves with larger batches. The timeline may extend slightly for very large orders, but the throughput rate stays consistent.
Get a Production Quote
If you’re planning a production run — whether it’s 50 units or 500:
- Send us the STEP or STL file
- Specify material, quantity, and any finishing requirements
- Tell us your target delivery date
We’ll respond with per-unit pricing, a production timeline, and any DfAM recommendations that could reduce cost without compromising the part.
Small batch doesn’t mean small-time. It means right-sized production with zero tooling risk.
