Combining 2D Sublimation with 3D Printing: A Complete Guide

Introduction

• Goal: Achieving full-color, photorealistic first layers using 2D sublimation and 3D printing
• Note: No special 3D printer is required
• Credit: Johan from Nerds PH for sharing the technique and test results

What is Sublimation?

• Definition: When a substance transitions directly from solid to gas without becoming liquid
• Dye Sublimation: Used in fabric printing (e.g., T-shirts) using a heat press to transfer dye from sublimation paper to fabric

Preparing the Setup

• Printer Choice: Epson EcoTank printers because they don’t use heat during printing
  • Example Models: EcoTank ET-1810 (Australia) and ET-2400 (USA)
• Conversion Steps:
  1. Fill the EcoTank reservoirs with sublimation dye instead of regular ink
  2. Use specialized bottle adapters, syringes, or a pre-assembled kit to transfer dye
  3. Run the printer initialization and calibrate it using the official app

Sublimation on Fabric

• Process:
  1. Print image on sublimation paper (mirror image in Photoshop)
  2. Place image face down on fabric with greaseproof paper underneath
  3. Use heat press (200°C for 1 minute, high pressure)
  4. Remove paper and greaseproof paper to reveal the transferred image

3D Printing with Sublimation

• First Test: Print image directly onto the 3D printer bed using glue stick
• Print Settings:
  • Low and slow first layers: 5-10 mm/sec print speed
  • No gaps in extrusion for complete transfer
  • Profiles and slicer settings adjustments (e.g., first layer squish, auto bed leveling)
• Results: Successful transfer of image to bottom of 3D print (e.g., TPU or PLA)

Optimal Settings and Techniques

• Print Settings Adjustments:
  • Low and slow first layer speeds (5-10 mm/sec)
  • Increased first layer squish (adjust Z-offset or start G-code)
  • Experiment with various infill patterns (e.g., concentric, HBT curve)
  • Use glue or blue painter's tape to hold sublimation paper in place

Enhancing Color Saturation

• Techniques:
  1. Use sublimation spray or double print image on sublimation paper
  2. Opt for matte filaments for better color results

Positioning and Alignment

• Methods:
  • Print a centering template on bed to align sublimation images
  • Use software tools to center prints and align registration marks
• Cleaning and Removal:
  • Easy removal of glue and residue with warm water and a scraper

Applications and Benefits

• Business Opportunities: Custom garments, phone cases, and other sublimated products
• Enhanced Print Quality: Custom textures and precise markings on 3D prints (e.g., control panels)
• Durability: Sublimation is highly durable, waterproof, and scratch-resistant

Conclusion

• Versatility: This technique expands the range of 3D printing applications
