• Rapid iteration: avoid mold waits and check engineering hypotheses quickly.
• Load testing: machined parts offer tight dims and predictable material behavior for load and heat tests.
• Printing vs milled parts: additive is quick for visual models but can show directional weakness or reduced strength in high-load tests.
• Injection trade-offs: injection and molded runs make sense at volume, but tooling expense often penalizes early stages.
• Choose CNC when: precision fit checks, assemblies needing exact feature relationships, and repeatable A/B comparisons.

UYEE Prototype helps select the optimal path for each stage, optimizing time, budget, and fidelity to reduce production risk and accelerate program milestones.

Design for Machining: CNC DfM Guidelines

A manufacturability-first approach focuses on tool access, stable features, and tolerances that support test objectives.

Automatic DfM checks at upload identifies tool access, wall thickness, and other risks so you can adjust the 3D model before production. UYEE helps match multi-axis selection to the geometry rather than 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 depends on material, but designing wider webs cuts chatter and tool deflection.

Use generous fillets at internal corners to allow proper cutter engagement. Deep, small pockets should be designed with ramped entries or multiple setups in mind.

Tolerance planning for appearance vs functional parts

Separate cosmetic and functional tolerances early. Tight form tolerances belong on mating surfaces. 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.

• Set 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 simple fixturing when speed matters.
• Specify best practices for threads, countersinks, and small holes to limit deflection and deliver repeatable quality.
• Early DfM reviews cut redesign and accelerate prototyping iterations.

Speed to Market: Lead Times and Low-Volume Runs

Expedited builds tighten timelines so engineers can advance from idea to test faster.

UYEE supports rapid prototyping with avg. lead time down to 2 days. Rapid scheduling and standardized setups cut lead time for urgent EVT and DVT builds.

Low-volume runs connect to pilot and enable assembly testing or limited market trials. Short-run parts keep the same inspection, documentation, and traceability as single-unit work.

Teams can reorder or revise parts quickly as development learning accumulates. Tactical use of CNC lets you defer expensive tooling until the design matures, minimizing sunk cost.

Reliable delivery rhythm aligns test plans, firmware updates, and supplier readiness so programs stay on schedule.

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 accept tooling for lower unit cost. For many low-quantity runs, machined parts beat molds on schedule and upfront cost. Printing is fastest 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 significant budget in cost. That makes it uneconomical for small lots.

Machined parts eliminate tooling and often provide tighter dimensional control and stronger material behavior than many printed parts. Chips from metal removal are reclaimed to reduce waste.

• 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 offers 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 stable, and material choice is locked. Use machined parts to validate fit, function, and assembly before cutting a mold.

Early DfM learnings from machined runs reduce mold changes and improve first-off success. Optimize raw stock, nest efficiently, and recycle chips to improve sustainability during the transition.

Beyond CNC: Additional 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-resolution 3D printing, and rapid injection molding to cover the full range of development needs.

Sheet metal fabrication uses laser cutting and bending for quick flat-pattern iterations. It is ideal for enclosures and brackets with formed features that are difficult or expensive to mill.

3D printing and SLA

SLA printing delivers smooth surfaces and fine detail for concept models and complex internal geometries. It enables fast visual checks and fit trials before committing to harder materials.

Rapid injection molding

Rapid tooling, family molds, and multi-cavity options enable bridging 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.
