- Rapid iteration: avoid mold waits and check engineering hypotheses quickly.
- Mechanical testing: machined parts deliver precise tolerances and stable material properties for load and thermal tests.
- Additive vs machined: additive is fast for visual models but can show anisotropy or lower strength in high-load tests.
- Injection molding trade-offs: injection and molded runs make sense at volume, but tooling cost often hurts early-stage choice.
- When to pick this method: high-precision fit checks, assemblies with critical relationships, and repeatable A/B comparisons.
UYEE Prototype advises on the best route for each stage, weighing time, budget, and fidelity to de-risk production and speed milestones.

Design for Machining: CNC DfM Guidelines
A CNC-aware approach focuses on tool access, stable features, and tolerances that meet test goals.
Automatic DfM checks at upload flags tool access, wall thickness, and other risks so you can adjust the 3D model pre-build. UYEE helps match multi-axis selection to the geometry instead of forcing a 3-axis setup to approximate a 5-axis method.
Geometry, tool access, and feature sizing for 3–5 axis
Keep walls appropriately thick and long enough features within the cutter reach. Minimum wall thickness varies by material, but designing wider webs reduces chatter and tool deflection.
Use generous fillets at internal corners to allow proper cutter engagement. Deep, small pockets should be designed with access ramps or multiple setups in mind.
Tolerance planning for appearance vs functional parts
Separate cosmetic and functional tolerances upfront. Tight form tolerances belong on critical interfaces. Looser cosmetic limits reduce cycle time and reduce cost.
Define datum schemes and tolerance stacks for assemblies and kinematic mechanisms. Document measurement plans for critical features so acceptance criteria are clear before the first run.
- Advise on minimum wall thickness, feature depths, and fillets to enhance tool access and stability.
- Use 5-axis when feature relationships or undercuts need single-setup accuracy; choose simpler fixtures when speed matters.
- Specify best practices for threads, countersinks, and small holes to limit deflection and ensure repeatable quality.
- Early DfM reviews cut redesign and speed prototyping iterations.
| Focus | Design Rule | Benefit |
|---|---|---|
| Wall & Fillet | Wider webs, radiused corners | Reduced deflection, better surface finish |
| Setups | Prefer 5-axis for complex relations | Fewer fixtures, preserved geometry |
| Tolerances | Functional vs cosmetic | Cost control, faster cycles |

| Run size | 1–200 units | Validation, pilot trials |
| Quality & docs | FAI, CoC, inspection reports | Regulated tests, production handoff |
| Flexibility | Fast reorders, design revisions | Iteration-driven development |
CNC vs Injection Molding and 3D Printing for Prototypes
Selecting the best process can cut weeks and costs when you move from concept to test parts.
Low quantities require a practical decision: avoid long waits or invest in tooling for lower unit cost. For many low-quantity runs, machined parts beat molds on schedule and upfront cost. Printing is quickest for concept visuals and complex internal lattices, but may not match mechanical performance.
Cost, time, and fidelity trade-offs at low quantities
Injection molding requires tooling that can take many weeks and thousands in cost. That makes it uneconomical for small lots.
Machined parts eliminate tooling and often deliver better dimensional control and stronger material behavior than many printed parts. Chips from metal removal are reclaimed to minimize scrap.
- Time: printing for hours to days; machining for days; injection may take weeks to months.
- Cost: low unit counts favor machining or printing; molding only pays off at volume.
- Fidelity: machining delivers consistent tolerances and surface finish; printing can show anisotropy and layer artifacts.
When to bridge from CNC prototypes to molding
Plan a bridge to injection when the design is stable, tolerances are locked, and material choice is locked. Use machined parts to validate fit, function, and assembly before committing to a mold.
Early DfM learnings from machined runs reduce mold changes and improve first-off success. Optimize raw stock, optimize nesting, and reclaim chips to improve sustainability during the transition.
| Attribute | Best for | Notes |
|---|---|---|
| Printing | Ultra-fast concepts, complex lattices | Low strength; good for visual and some functional tests |
| Machining | Small lots, tight tolerances, mechanical tests | Avoids tooling; recyclability reduces waste |
| Injection | High-volume production | High upfront tooling; lowest unit cost at scale |
Beyond CNC: Complementary On-Demand Manufacturing
Modern development needs a suite of on-demand methods that match each milestone.
UYEE Prototype augments its offering with sheet metal, high-accuracy 3D printing, and rapid injection molding to cover the full range of development needs.

3D printing and SLA
SLA printing provides smooth surfaces and fine detail for concept models and complex internal geometries. It enables fast visual checks and fit trials before moving to harder materials.
Rapid injection molding
Rapid tooling, family molds, and multi-cavity options let teams bridge to higher volumes once designs stabilize. Overmolding can add soft-touch or bonded layers in the same run.
Multi-process programs often mix CNC parts with printed components or sheet metal to accelerate subsystem integration. Material and process selection prioritize validation goals, schedule, and budget.
- Sheet metal: fast iterations for formed parts and brackets.
- SLA printing: high-accuracy surfaces and internal detail.
- Rapid molding: cost-effective bridge when volumes justify tooling.
