Can you make enamel pins with 3D printer?

Enamel pins have become a popular form of self-expression and collectibles, allowing individuals to showcase their unique style and interests. If you're wondering whether it's possible to make enamel pins with a 3D printer, you're about to embark on an exciting journey!


In this blog post, we will delve into the world of combining 3D printing technology with enamel pin production. From design creation to printing and finishing, we'll guide you through the step-by-step process of bringing your 3D-printed enamel pins to life.


Understanding 3D Printing for Enamel Pins:

Traditional enamel pins are typically made using a metal mold and enamel fillings. However, with advancements in 3D printing technology, it is now possible to create intricate designs and unique shapes that were once challenging or costly to produce through traditional methods. 3D printing opens up a whole new world of creativity and customization for enamel pin enthusiasts.


Step-by-Step Guide to Making Enamel Pins with a 3D Printer:


Step 1: Design Creation:

  • Begin by brainstorming ideas for your enamel pin design. Consider the size, shape, and intricate details you want to incorporate.
  • Use 3D modeling software such as Tinkercad, Fusion 360, or Blender to bring your design to life. Familiarize yourself with the software's tools and capabilities.
  • Ensure that your design fits within the size limitations and requirements of your 3D printer.


Step 2: 3D Printing Preparation:



  • Export your design as an STL file, which is the standard file format used for 3D printing.
  • Import the STL file into slicing software, such as Cura or Simplify3D, which prepares the design for printing. Adjust settings such as layer height, print speed, and infill density based on your desired pin specifications and the capabilities of your 3D printer.
  • Generate the G-code file, which contains the instructions for your 3D printer.


Step 3: 3D Printing:


  • Preheat your 3D printer according to the filament material you will be using. Common materials for enamel pins include PLA or resin. 
  • Load the filament into the 3D printer and ensure proper alignment.
  • Attach the build plate or resin vat securely.
  • Transfer the G-code file to your 3D printer and start the printing process.
  • Monitor the printing progress, ensuring that the layers are being deposited accurately and the design is taking shape.


Step 4: Post-Processing:

  • Once the printing is complete, carefully remove the printed pin from the build plate or resin vat.  
  • If using filament-based 3D printing, remove any support structures by carefully cutting or sanding them off.
  • Clean the pin using isopropyl alcohol or a similar cleaning agent to remove any residual printing material.
  • Depending on the filament material and desired finish, you can further refine the pin's surface by sanding, polishing, or painting it.


Step 5: Adding Enamel Filling:


  • While traditional enamel pins involve filling the recessed areas with enamel, with 3D-printed pins, you can explore alternative methods to achieve a similar effect.
  • One option is to use UV resin or epoxy resin to fill the recessed areas, giving them a glossy, enamel-like appearance.
  • Carefully apply the resin using a small brush or pipette, ensuring that it fills the intended areas without overflowing.
  • Allow the resin to cure according to the manufacturer's instructions.


Step 6: Attach Pin Backs


  • Once the enamel filling has cured, it's time to attach the pin backs to your 3D-printed pin.
  • Apply a small amount of strong adhesive or epoxy glue to the back of the pin.
  • Attach a pin post and back, ensuring they are aligned and securely in place.
  • Allow the adhesive to dry completely before handling the pin.


Step 7: Finishing Touches:

  • Inspect your finished 3D-printed enamel pin for any imperfections or loose parts.
  • If desired, apply a pin sealing agent or clear coat to protect the pin's surface and enhance its durability. 
  • Clean the pin gently with a soft cloth to remove any fingerprints or smudges.


The combination of 3D printing technology and enamel pin production opens up endless possibilities for creativity and customization. By harnessing the power of 3D modeling and printing, you can bring intricate designs to life and create truly unique enamel pins that reflect your individual style.

With careful design, printing, and post-processing, you can proudly wear or share your 3D-printed enamel pins, showcasing your craftsmanship and innovation in the world of pin collecting. So, grab your 3D printer and start turning your imagination into tangible and stunning enamel pins!
