When designing custom lapel pins, choosing between 2D and 3D construction is an important decision. The difference is not simply about appearance. It also affects the artwork, tooling, metal relief, enamel placement, production method, cost, and final visual impact.
Soft enamel can be used with both 2D and 3D metal constructions. The best option depends on whether your design needs a flat graphic appearance or raised dimensional details.

| Best use | Corporate, clubs, events | Firefighter, military, commemorative |
What Is a 2D Soft Enamel Lapel Pin?
A 2D soft enamel pin has a primarily flat metal surface with raised metal borders separating the enamel colors.
For example, a company logo might contain:
- Gold metal outline
- Blue enamel
- Red enamel
- Black enamel
The metal lines define each color area.
The enamel sits below the raised metal borders, creating the characteristic soft enamel texture.
What Is a 3D Soft Enamel Lapel Pin?
A 3D soft enamel lapel pin adds dimensional metal relief to the basic enamel construction.
Instead of having only one flat metal level, the design can contain:
- Raised areas
- Recessed areas
- Multiple relief levels
- Sculpted shapes
- Curved surfaces
For example, a firefighter pin could feature a raised fire helmet while the surrounding areas contain red or black soft enamel.
The Biggest Difference: Relief
The simplest way to understand the difference is:
2D
Flat metal + raised borders + recessed enamel
3D
Sculpted metal + multiple relief levels + recessed enamel
The enamel itself does not necessarily make the pin 3D.
The metal construction underneath the enamel creates the primary dimensional effect.
When Should You Choose 2D Soft Enamel?
2D is usually the better option when the design is primarily graphical.
Good applications include:
- Company logos
- School logos
- Club pins
- Association pins
- Event pins
- Membership pins
- Simple military insignia
- Promotional pins
If your artwork consists mainly of:
Text + logo + simple shapes + flat colors
2D is often sufficient.
When Should You Choose 3D Soft Enamel?
3D becomes more useful when the design depends on physical depth.
Good applications include:
- Firefighter helmets
- Police equipment
- Military vehicles
- Aircraft
- Animals
- Buildings
- Human figures
- Sculpted shields
- Complex organizational emblems
If your design needs to show height, depth, curves, or multiple levels, 3D is worth considering.
Example: Corporate Logo
Suppose your logo looks like this concept:
Company name + shield + three colors
There may be no reason to create a complicated 3D mold.
Recommended:
2D soft enamel
Why?
- Simple artwork
- Clear colors
- Easy to read
- Lower manufacturing complexity
- Efficient for larger quantities
Example: Firefighter Lapel Pin
Now consider a design containing:
- Maltese cross
- Fire helmet
- Axes
- Ladder
- Department number
- Fire flames
A flat design could reproduce the artwork, but it would not create much physical depth.
Recommended:
3D metal + soft enamel
The helmet and other elements can be raised while the enamel fills selected recessed areas.
This gives the pin much stronger visual depth.
Example: Military Aircraft Pin
Imagine a pin featuring an aircraft.
A 2D version could show:
- Aircraft outline
- Squadron name
- Unit number
- Enamel colors
A 3D version could add:
- Raised wings
- Raised cockpit
- Sculpted fuselage
- Recessed background
If realism is important:
3D is the better option.
If the design is primarily an insignia:
2D may be more appropriate.
2D Soft Enamel: Main Advantages
1. Simple Manufacturing
The construction is relatively straightforward.
2. Good for Logos
Flat artwork translates naturally into 2D.
3. Clear Color Separation
Raised metal borders clearly separate enamel colors.
4. Good for Text
Flat surfaces make it easier to maintain readable lettering.
5. Cost Efficiency
For many designs, 2D requires less complex tooling than 3D.
3D Soft Enamel: Main Advantages
1. Strong Visual Impact
The raised metal creates depth.
2. More Realistic Designs
Sculpted objects can look more recognizable.
3. Better for Complex Shapes
Curved and dimensional elements can be incorporated.
4. Premium Appearance
A well-made 3D pin can have a collector-style appearance.
5. More Design Freedom
The manufacturer can use different relief levels to emphasize important parts of the artwork.
Does 3D Always Mean Better?
No.
A 3D pin is not automatically better than a 2D pin.
For a simple logo, unnecessary 3D relief can make the design:
- More expensive
- More complicated
- Less visually clean
If the artwork is flat and graphic, 2D may actually produce a better result.
The goal should be:
Use the simplest construction that accurately communicates the design.
Soft Enamel + 2D vs 3D Cost
The exact price depends on the manufacturer, but 3D construction generally requires more complex tooling and engineering.
An illustrative example:
1,000 pieces
2D soft enamel
- Production: $0.80/pc
- Tooling: $80
- Packaging: $80
Estimated subtotal:
$960
3D soft enamel
- Production: $1.05/pc
- Tooling: $150
- Packaging: $80
Estimated subtotal:
$1,280
The figures above are illustrative examples only, not fixed quotations.
The actual price depends on:
- Size
- Material
- Thickness
- Design complexity
- Number of colors
- Plating
- Quantity
- Packaging
How Size Affects the Choice
Size is especially important.
20–25 mm
Small designs should generally avoid excessive detail.
2D may be easier for:
- Logos
- Text
- Symbols
30–40 mm
This size provides more space for:
- 3D relief
- Multiple colors
- Department numbers
- Detailed emblems
50 mm+
Large pins can accommodate more dimensional elements, but the manufacturer still needs to evaluate the artwork.
2D vs 3D for Small Text
If your design contains a lot of text, 2D may be easier to manage.
For example:
25 mm pin + 15 letters
may require simplified typography.
3D relief does not automatically make tiny text more readable.
Instead, consider:
- Increasing the pin size
- Reducing text
- Increasing letter thickness
- Removing unnecessary wording
2D vs 3D for Firefighter Pins
Firefighter designs are a good example of where the choice depends on the artwork.
Choose 2D when:
- Maltese cross is simple
- Text is important
- Department logo is flat
- Production quantity is large
- Budget is important
Choose 3D when:
- Fire helmet is prominent
- Equipment needs to be sculpted
- The design has multiple relief levels
- A collector-style appearance is desired
2D vs 3D for Military Pins
2D
Good for:
- Unit insignia
- Text
- Stars
- Shields
- Simple emblems
- Flags
3D
Good for:
- Aircraft
- Tanks
- Eagles
- Ships
- Sculpted weapons or equipment
- Detailed commemorative designs
2D vs 3D for Police Pins
Police-related designs often include:
- Shields
- Stars
- Eagles
- Badges
- Department numbers
- City names
A traditional badge-style design can work well as 2D.
A detailed eagle, vehicle, or sculpted emblem may benefit from 3D construction.
2D vs 3D for Corporate Pins
For most corporate logos:
2D is usually enough.
The company’s visual identity should remain clear and recognizable.
3D can be considered when the company wants:
- A premium employee award
- An anniversary pin
- A collector item
- A highly dimensional logo
How Plating Changes the Appearance
Both 2D and 3D pins can use different plating finishes.
Common options include:
- Bright gold
- Bright silver
- Antique gold
- Antique silver
- Bronze
- Black nickel
2D + Bright Gold
Clean and modern.
2D + Antique Silver
Traditional and institutional.
3D + Antique Gold
Strong contrast that emphasizes relief.
3D + Antique Silver
Excellent for sculpted designs.
How Enamel Colors Affect the Design
Soft enamel is particularly useful when the design needs strong color contrast.
For example:
Red + black + gold
can create a powerful firefighter-style design.
However, too many colors can make a small pin visually crowded.
For small pins, consider simplifying the palette.
Material Choices for 2D and 3D
2D Soft Enamel
Common materials:
- Brass
- Iron
- Zinc alloy
Brass is often suitable for detailed metal lines.
Iron can be considered for cost-sensitive projects.
3D Soft Enamel
Zinc alloy is particularly useful for:
- Sculpted relief
- Curved surfaces
- Complex shapes
- Multi-level designs
Brass can also be used for certain dimensional constructions depending on the design and manufacturing method.

Common Mistakes
Mistake 1: Making Every Design 3D
3D is unnecessary for many simple logos.
Mistake 2: Making a Complex Design 2D
A detailed sculpted object may lose its character when flattened.
Mistake 3: Ignoring Pin Size
Tiny designs cannot reproduce unlimited detail.
Mistake 4: Using Too Much Text
Text should remain readable at the actual physical size.
Mistake 5: Comparing Prices Without Matching Specifications
Compare suppliers using the same:
- Size
- Material
- Thickness
- Enamel
- Plating
- Quantity
- Backing
- Packaging
