Production workflow

How a CNC part in Polycarbonate ships.

From CAD upload to crated delivery. Every step is timestamped on the digital traveler that arrives with your parts.

  1. 01

    DFM review

    Applications engineer validates thin walls, draft angles, and CNC-specific constraints within 4 business hours.

  2. 02

    Build prep

    Nesting, support generation, and tool-path optimization on calibrated 5-Axis CNC Machining machines.

  3. 03

    Production

    Lights-out runs on certified engineering thermoplastic stock. Operator initials logged at every shift change.

  4. 04

    QC & ship

    CMM verification on critical dimensions, then DDP shipping with full traceability.

Post-processing

Finishing options

Every CNC part ships with standard post-processing included. Upgrade at quote time for parts that need to look (or behave) like production.

  • As-machined (Ra 1.6 µm)

    Standard surface; included.

  • Bead-blast matte

    Uniform matte; hides tool marks.

  • Type II / Type III anodize

    Color or hard-coat; mil-spec available.

  • Powder coat (RAL)

    Cosmetic + corrosion protection.

"We were quoting CNC Polycarbonate parts across three vendors with two-week lead times. 3DBuildBot collapsed that to a single dashboard with same-day DFM feedback. It's how we ship hardware on a weekly cadence now."

FAQ

CNC Polycarbonate — common questions

What tolerance can I actually hold on a CNC part?
Our published baseline is ± 0.05 mm (ISO 2768-fH), measured XY-plane on as-built parts. Tighter tolerances (down to ± 0.025 mm) are available on call-out features with a tolerance stack review.
Is Polycarbonate certified for electronics use?
Polycarbonate carries UL 94 V-0, RoHS. ESD-safe handling and IPX-rated enclosure designs supported. Full certificates of conformance ship with every order.
What's the maximum part size?
Our build envelope for this process is 800 × 500 × 400 mm. Larger assemblies are split, printed in sections, and bonded or mechanically joined — ask for a DFM consult.
Can you scale this from prototype to production?
Yes. The same machines and material lots used for your prototype run your production order — no re-qualification needed. Volume pricing kicks in at 50 units and again at 500.
How is pricing calculated?
Material volume × per-cm³ rate + machine setup fee + post-processing + platform markup. The widget above shows the live breakdown — no hidden fees at checkout.
