Additive Manufacturing & Hybrid Production Solutions
Critical Dimensions CNC integrates FDM 3D printing directly alongside our precision CNC machining centers. When you submit a CAD model we personally evaluate the geometry and functional requirements of your parts to recommend the optimal manufacturing path—whether additive, subtractive, or a hybrid combination of both. You get the best process for your application from a single, accountable, trustworthy supplier.
When sourcing a rapid prototype or custom component, the real goal is getting a functional part on time—not forcing a specific manufacturing method.
Single-process vendors naturally steer quotes toward the equipment they own. By combining 3D printing and precision CNC machining in-house, Critical Dimensions CNC eliminates vendor bias and matches your geometry to the fastest, most cost-effective process.
Standardized Quality on Every 3D Printing Run
Every additive project undergoes the exact same pre-print engineering review, build setup, and post-process inspection—whether you order a single prototype or a full production lot.
- In-House Additive Production. Industrial, multi-material 3D printing operated directly on our floor for rapid turnaround and tight process control.
- Single-Source Hybrid Capability. Printed prototypes and precision CNC machined components sourced from one supplier—eliminating vendor handoffs and split purchase orders.
- Broad Filament & Polymer Versatility. Full capability to print most all filament grades.
- Direct Engineering File Review. CAD models and prints are evaluated directly by senior manufacturing leadership.
- Objective Process Selection Guidance. Honest, upfront engineering advice on whether additive manufacturing or CNC machining best fits your load, tolerance, and budget goals.
- Pre-Shipment Dimensional Verification. Every printed part is inspected against drawing and CAD requirements prior to release.
How 3D Printing Works at Critical Dimensions CNC
Send the File
Submit your model or drawing through the website form or by email to [email protected]. Phone quotes start at (443) 517-9123, Monday–Friday, 8am–6pm.
File Review
The geometry gets reviewed against what the part has to do.
Process Recommendation
You get a straight answer on whether the part should be printed or machined. A shop with both options on the floor has no reason to push you toward one.
Production
The part gets built on the shop's printers, or routed to CNC equipment when machining is the better fit.
Inspection and Delivery
Parts are reviewed against drawing requirements before shipment. Invoicing follows on Net 15 terms.
Should My Part Be 3D Printed or Machined?
Process selection depends entirely on structural demands, geometry, and tolerances. 3D printing is ideal for intricate, hard-to-fixture shapes and rapid form-and-fit validation where mechanical loads are secondary. Precision machining is the clear choice when high structural strength, tight dimensional accuracy, or smooth mating surfaces are required. Send us your model upfront—we will evaluate the geometry and recommend the safest, most cost-effective manufacturing path before you place an order.
Additional Services That Support Printed Parts
Printed parts leave the shop for Aerospace & Defense, electronics, robotics, medical, marine, and automotive customers.
CNC MillingMilling on CNC machining centers, plus conventional milling for work that does not require a full CNC setup.
CNC TurningTurned parts on live tooling capable equipment, so milled features can be completed in the same setup.
Reverse EngineeringExisting parts measured and modeled when no drawing is available.
3D Printing and the Standards Behind Additive Manufacturing
Additive manufacturing arrived in industry faster than the language to describe it. Two shops could use the same term for different processes, which made specifying a printed part difficult for buyers.
ASTM International Committee F42 was formed in 2009 to close that gap. The committee now carries a membership above 766 and runs eight technical subcommittees, with all of its standards published in Volume 10.04 of the Annual Book of ASTM Standards. Working with ISO, F42 produced the joint terminology standard that defines the vocabulary the industry uses to describe additive processes.
For a buyer, the practical value of that work is a shared language. Describing what the part has to do, rather than naming a process, gets you a better answer from any shop worth quoting.
Frequently Asked Questions About 3D Printing
What file formats does Critical Dimensions CNC accept?
We accept almost all major 3D and 2D CAD formats. For the fastest turnaround and cleanest geometry, please send STEP files for machined parts and 3MF or STL files for 3D printed parts.
Can Critical Dimensions CNC Print and Machine the Same Project?
Yes. By operating 3D printers alongside our CNC machining centers under one roof, we handle multi-process assemblies without splitting your order across separate vendors. You get full accountability for both additive and machined components under a single purchase order.
Can Critical Dimensions CNC Print One-Off Parts?
Yes. Single prototypes and low-volume runs are a core reason engineers and product developers partner with our team. While larger vendors build their schedules around high-volume production and routinely decline short runs, we are structured for both prototype and production runs.
How Do I Request a 3D Printing Quote?
Submit your CAD model through our website form or email it directly to [email protected]. For immediate phone consultations, call (443) 517-9123 Monday through Friday, 8:00 AM – 6:00 PM EST.
What are the payment terms for printed parts?
Critical Dimensions CNC offers Net 15 terms and accepts ACH, check, and credit card. Specific terms can be discussed.
Ready to Get Your Part Quoted?
3D printing works best when someone looks at the part before recommending a process. That is how Critical Dimensions CNC has operated since December 2022 — reviewing the model, asking what the part has to do, and answering honestly when machining is the better call. Send your file and find out.
