Delivery nationwide across Vietnam in 1–3 days after completion, with international shipping available on request.

Many customers come to CT3D with a very practical question: “I have a drawing – can someone cut this for me?” One needs 50 MDF panels engraved with a logo. Another needs a 3 m tall foam mascot for an event. Another needs a plastic product mock-up for a photo shoot. All of these are custom CNC machining jobs. This page explains what CT3D can do, which materials to choose, how the process works and when to use CNC instead of 3D printing. If you are new to the topic, see also our article on what CNC machining is and how it differs from 3D printing.

Choose your CNC machining service

CT3D’s CNC work is organized by material, because wood, foam and sheet materials need different machines, tools and finishing. Start with the service that matches your material; if a project mixes materials or needs fine details, our engineers combine CNC with 3D printing in the same order.

How to choose: CNC services compared

Service	Materials	Best for	Typical finish
CNC wood machining	MDF, HDF, plywood, solid wood	Signage, reliefs, furniture parts, wood molds, decor	Sanded, sealed, painted or edge-banded
CNC foam cutting	EPS, XPS foam	Mascots, 3D lettering, site models, composite cores, very large lightweight shapes	Filler and paint, or a composite skin for durability
CNC plastics, acrylic and aluminum sheet (this page)	Acrylic, plastic sheet, aluminum sheet	Nameplates, display boxes, mounting plates, simple jigs, mock-up parts	Clean cut edges; drilled and pocketed as drawn
3D printing (alternative)	FDM plastics, resin, PA12, metal	Complex shapes, hollow interiors, small details, undercuts	Raw, sanded or painted

What does CT3D’s CNC machining service include?

CNC stands for Computer Numerical Control. Put simply, the machine reads toolpaths from a file and moves the cutting tool along the X, Y and Z axes to remove excess material. It is a “subtractive” process – the opposite of 3D printing, which “adds” material layer by layer.

At CT3D, CNC machining is organized into the following main service groups:

• CNC wood cutting and engraving: profile cutting of MDF, HDF and plywood; lettering and logo engraving; 2.5D and 3D relief milling; table legs, furniture components, wood molds and decor items.
• CNC EPS/XPS foam cutting: mascots, 3D event lettering, site models, display models and cores for composite fabrication. CT3D uses a 5-axis foam CNC machine for large volumes and complex curved shapes.
• CNC plastics, acrylic and aluminum sheet: sheet cutting, pocket milling and drilling for enclosures, nameplates, simple jigs and mock-up parts.
• Mock-ups and presentation models: CNC combined with 3D printing, sanding and painting to produce appearance models that look like the real product.
• Mold machining: wood molds, foam molds and master patterns for silicone molds or composite molds.

What sets CT3D apart is that you do not have to coordinate several workshops. A part can have its frame CNC milled, small details 3D printed, and then be assembled, sanded, painted and delivered – all in one place.

CNC machining materials: which one is right for the job?

Choosing the right material is the best way to keep costs down. The table below summarizes the materials CT3D machines most often and their best-fit applications.

Material	Key characteristics	Best-fit applications	Notes
MDF / HDF	Smooth, uniform, easy to mill and paint	Reliefs, signage, wood molds, decor, mock-ups	Sensitive to water; needs a full sealing primer in humid locations
Solid wood	Attractive grain, durable, directional fibers	Table legs, carvings, furniture	Grain affects edge quality; should be kiln-dried first
Plywood	Light, stiff, multi-layer	Frames, partitions, jigs, shelving	Exposed layers on edges; can be edge-banded or painted
EPS foam	Very light, inexpensive, fast to cut	Mascots, site models, 3D lettering, composite cores	Beaded surface; needs filler/paint or a composite skin
XPS foam	Smoother and harder than EPS	Architectural models, parts needing sharp edges	Higher material cost than EPS
Acrylic / plastic sheet	Clear or colored, glossy surface	Nameplates, display boxes, mock-up housings	Requires suitable feeds and speeds to avoid melting or edge cracking
Aluminum sheet	Light, strong, thermally conductive	Mounting plates, simple flanges, technical parts	For complex metal parts, consider metal 3D printing

If you are unsure what to choose, just tell us where the product will be used (indoors or outdoors), whether it carries load, whether it needs to be lightweight or durable, and your deadline. CT3D’s engineers will recommend a material and machining approach.

When should you choose CNC, and when 3D printing?

This is the question CT3D hears most often. No single technology is best for everything – each excels at a particular type of geometry and production volume.

Criterion	CNC machining	3D printing
Principle	Removes material from a block or sheet	Adds material layer by layer
Strongest geometry	Flat panels, 2D profiles, reliefs, large blocks	Complex shapes, hollow interiors, small details, undercuts
Large sizes	Very well suited (foam, large wood blocks)	Must be segmented and assembled when exceeding the machine envelope
Materials	Wood, foam, acrylic, plastic sheet, aluminum	FDM plastics, resin, PA12, metal
Surface	Depends on stepover; flat faces are excellent	Visible layer lines (FDM) or very smooth (resin)
Quantity	Good for repeated sheet-cutting runs	Good for one-offs, low volumes and varied shapes

Source: CT3D technical summary.

A simple example: a 2 m long raised-letter sign in MDF is much faster and cheaper to CNC than to 3D print. Conversely, a small character figure with hair, fingers and intricate relief will come out better with resin 3D printing. For metal parts, see our comparison of metal 3D printing and CNC to learn when it makes sense to combine the two technologies.

Combining CNC and 3D printing in one project

Many of the best projects use both. A large mascot can have a CNC-cut foam body with 3D printed eyes, logo and small details, then be coated in composite and painted. A product model can have an MDF-milled base frame and a curved shell printed in resin. This approach reduces cost while preserving detail.

Applications of custom CNC machining

CNC machining is used across many industries. Here are the types of work CT3D handles most often:

• Events and advertising: 3D lettering, large-format logos, backdrops, mascots and enlarged product models.
• Architecture and real estate: site models, massing models, terrain and facades.
• Interiors and decor: table legs, CNC-patterned screens, wall reliefs and decorative pieces.
• Religious art and fine art: reliefs, statue blanks and master patterns for casting. CT3D’s projects include the restoration of an Our Lady of La Vang statue and a Ca Mau shrimp landmark model.
• Product development and R&D: appearance mock-ups, jigs, trial molds and master patterns for silicone molds.
• Education: student project models and teaching models.

For mascots, the detailed process is covered in our article on making mascots with CNC foam and composite. If you need to reproduce many parts from a CNC master, see our article on making silicone molds from a master pattern.

What are the steps in CT3D’s CNC machining process?

CT3D follows six clear steps so you always know where your order stands:

1. Send your files: 2D drawings (DXF, DWG, AI, vector PDF) or 3D files (STEP, STL, OBJ, 3MF) via our Contact form, Zalo or email. No files yet? Send photos, sketches and dimensions.
2. Technical requirements: material, dimensions, quantity, finish level (raw, sanded, painted) and deadline.
3. Engineering file review: we check dimensions, minimum tool radius, engraving depth and segmentation, and calculate material volume.
4. Quote with lead time: CNC machining is quoted to your drawing, because price depends on material, machine time and finish level.
5. Confirmation and production: toolpath programming, machining, inspection and finishing.
6. Delivery: door-to-door delivery or collection from our workshop. Shipped by domestic courier, post or air freight; nationwide delivery within Vietnam in 1–3 days after completion. International shipping can be arranged on request.

What if you don’t have a drawing?

CT3D offers 3D CAD modeling, redrawing from photos, and 3D scanning with reverse engineering from a physical sample. The file is then optimized for CNC: closed profiles, layering, block segmentation and finishing allowances.

What determines the cost of CNC machining?

CT3D does not publish a fixed CNC price list, because two parts of the same size can differ several-fold in labor. Prices are quoted to your drawing based on the following factors:

• Material and stock size: MDF, solid wood, foam, acrylic and aluminum each have different material costs and cutting speeds.
• Machining type: 2D profile cutting is fastest; 2.5D engraving is moderate; 3D surface milling of curved shapes takes the most machine hours.
• Surface finish: the smaller the stepover, the smoother the surface – but the longer the run time.
• Size and number of setups: parts that need flipping, block segmentation or multi-part assembly require extra labor.
• Quantity: producing many identical panels lowers the setup cost per piece.
• Finishing: sanding, priming, color painting and composite coating are charged separately.
• File preparation and rush orders: charged extra if 3D modeling or expedited delivery is required.

Cost-saving tips: nest multiple parts on the same sheet; avoid very sharp internal corners (a round tool cannot cut a perfectly square corner); and only specify a high-quality finish on visible faces.

Common mistakes when ordering CNC machining – and how to avoid them

• Open contours in 2D files: profiles that are not closed leave the machine unable to identify the cutting area. CT3D will check and join them, but you should export a clean vector file.
• Perfectly square internal corners: milling cutters have a radius, so internal corners are always slightly rounded. If you need square corners for assembly, let us know so we can design dog-bone relief cuts.
• Features that are too thin: very thin letter strokes or ribs break easily when cutting wood or foam. Increase the thickness or move that feature to 3D printing.
• Wrong material for the environment: unsealed MDF placed outdoors will swell. Outdoor foam needs a composite coating.
• No assembly clearance: two parts cut to “exactly the same size” usually won’t fit together. Allow a clearance suited to the material.
