CNC Machining

When the part needs to be metal, whether aluminium, brass, or hardwoods, CNC delivers tolerances and surface finish that 3D printing can't.

3D printing is brilliant for shape and complexity. CNC wins on material and tolerance. When you need a part to be actual metal with precise dimensions, FDM and SLA can’t compete.

When CNC over 3D printing

  • The part is load-bearing and metal is the right answer
  • You need ±0.05mm tolerance on mating surfaces
  • The volume is 5–50 units where each one matters
  • Surface finish from machining is part of the design intent (polished aluminium, brushed brass)

When 3D printing wins instead

  • Complex internal geometry that’s machine-impossible
  • Quick prototype iteration where 3-day CNC turnaround is too slow
  • Single-unit demonstration parts where appearance matters more than mechanical strength

How to spec a CNC job

Send a STEP file with tolerances called out where they matter. We’ll respond with a quote and any DFM (design-for-manufacturability) flags within the same business day.

What's included
  • 3-axis milling
  • Aluminium 6061, 7075
  • Brass C360
  • Hardwoods (teak, walnut, oak)
  • Engineering plastics (Delrin, POM, nylon)
  • Tolerances to ±0.05mm
How we make it
  1. CAD & DFM review

    Send a STEP file with critical tolerances called out. We flag draft, undercuts, and any geometry that costs more than it should.

  2. Material selection

    Aluminium 6061/7075, brass C360, Delrin, POM, or hardwoods. We pick stock that matches the application's mechanical and aesthetic spec.

  3. Toolpath programming

    CAM programming with the right tooling, feeds, and speeds for the material and surface finish you need.

  4. CNC machining

    3-axis milling with tolerances down to ±0.05mm. Cutting fluid, climb cuts, and finish passes for a clean surface straight off the machine.

  5. Inspection & finishing

    First-article inspection with digital calipers and pin gauges. Optional bead blast, brushed, or anodised finishes before delivery.

Frequently asked

How much does CNC machining cost in Singapore?

CNC parts start from S$80 per part, with the final price set by material, size and complexity. Send a STEP file with your critical tolerances called out and we return a quote plus any design-for-manufacturability flags within the same business day. Volume discounts kick in from 10 units, around 10 percent at 10 to 24 pieces and 20 percent at 25 to 99.

What materials can you CNC machine?

We machine aluminium 6061 and 7075, brass C360, engineering plastics like Delrin, POM and nylon, and hardwoods such as teak, walnut and oak. Aluminium suits structural brackets and prototype enclosures, brass works for premium hardware and signage badges, and the plastics handle low-friction wear parts. We pick stock that matches both the mechanical and the aesthetic spec of your part.

How tight a tolerance can you hold on CNC parts?

We hold tolerances down to plus or minus 0.05mm on 3-axis milling, which is why CNC beats FDM and SLA when mating surfaces have to fit. Every job gets first-article inspection with digital calipers and pin gauges before it leaves the studio. Call out the tight dimensions on your STEP file so we tool and program for them specifically.

What file do I send and how long does a CNC job take?

Send a STEP file with the critical tolerances marked, and we reply with a quote and any DFM flags the same business day. Standard CNC turnaround runs about 5 to 7 working days once the design is confirmed, so for fast prototype iteration 3D printing is often the better call. Collect from our studio at 994 Bendemeer Road or we courier islandwide.
