Design for Machining: Prototyping Guidelines

A DfM-first approach prioritizes tool access, stable features, and tolerances that meet test goals.

Automated DfM feedback at upload flags tool access, wall thickness, and other risks so you can refine the 3D model before production. UYEE aligns multi-axis selection to the geometry rather than forcing a 3-axis setup to mimic a 5-axis method.

Geometry, tool access, and feature sizing for 3–5 axis

Keep walls appropriately thick and features within cutter reach. Minimum wall thickness depends on material, but designing wider webs cuts chatter and tool deflection.

Use radiused 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 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.

• 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 simpler fixtures when speed matters.
• Specify best practices for threads, countersinks, and small holes to limit deflection and deliver repeatable quality.
• Early DfM reviews reduce redesign cycles 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

Speed to Market: Lead Times and Low-Volume Runs

Rapid builds shorten schedules so engineers can progress to testing quickly.

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

Low-volume runs bridge the gap to pilot and enable assembly testing or limited market trials. Short-run parts keep the same inspection, documentation, and traceability as one-off parts.

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

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

Attribute	Typical Range	When to Use
Lead time	1–5 days (avg 2 days)	Urgent engineering builds
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

Choosing the right fabrication route can save weeks and budget when you move from concept to test parts.

Small batches require a practical decision: avoid long lead times or accept tooling for lower unit cost. For many low-quantity runs, machined parts surpass 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 demands tooling that can take months and thousands in cost. That makes it uneconomical for small lots.

Machined parts avoid tooling fees and often deliver better dimensional control and stronger bulk properties than many printed parts. Chips from metal removal are recyclable to improve sustainability.

• 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 layer anisotropy and layer artifacts.

When to bridge from CNC prototypes to molding

Plan a bridge to injection when the design is frozen, tolerances are stable, and material choice is locked. Use machined parts to prove fit, function, and assembly before committing to a mold.

Early DfM learnings from machined runs cut mold changes and increase first-off success. Right-size raw stock, optimize nesting, and recycle 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: Adjacent On-Demand Manufacturing

Modern development benefits from a suite of on-demand methods that fit 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 fast 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 provides smooth surfaces and fine detail for concept models and complex internal geometries. It supports fast visual checks and fit trials before moving to harder materials.

Rapid injection molding

Rapid tooling, family molds, and multi-cavity options enable bridging to higher volumes once designs are stable. Overmolding can add soft-touch or bonded layers in the same run.

Multi-process programs often combine CNC parts with printed components or sheet metal to speed subsystem integration. Material and process selection focus on 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.

Method	Best use	Key benefit
