NC-Cylinder Elf-mini Irregularly shaped thermos cup modeling​ enables high-quality 360° UV printing on tapered, изогнутый, or complex thermos cups. The NC-Cylinder Elf-mini supports objects 80–280 mm in length and Φ45–100 mm in diameter, с конусом до <5°, and supports 2–8 mm high-drop printing driven by intelligent laser shape-sensing and positioning. Equipped with an Epson I3200-U1HD printhead in CMYK+W+V mode, it delivers up to 1200 точки на дюйм. Modeling an irregular cup correctly—measuring its geometry, setting the tilt angle, mapping the print zone, and validating via test prints—ensures vibrant, seamless wraps without banding or misalignment.

Cup Geometry Measurement

Begin by measuring the cup’s length, diameter at top and bottom, and taper angle. Confirm the cup falls within the printable range: length 80–280 mm, diameter Φ45–100 mm, taper <5°. Record the circumference for full-wrap artwork sizing—incorrect circumference leads to image stretching or compression at the seam. Identify the most centered or flat print zone, and note any handles, lips, or seams that may interrupt smooth rotation.

Fixture and Tilt Setup

Mount the cup on the rotary chuck using a suitable jig. For tapered cups, adjust the Elf-mini’s flexibly adjustable tilt angle to bridge the height difference across the curved surface, keeping tilt within 5° to maintain accuracy. Silicone grippers or inserts prevent slippage without scratching. Ensure the cup is centered and firmly clamped—over-tightening may dent the surface.

Laser Shaping and RIP Configuration

Activate the intelligent laser positioning system. The laser automatically measures the cup’s shape and determines the optimal printing trajectory, while the 2–8 mm high-drop capability handles surface irregularities. In the RIIN RIP software, import your artwork and map it to the measured print zone. Use distortion tools to simulate curve wrapping, keep essential elements like logos centered, and enable contour wrapping if available for precision alignment. For metallic or colored cups, configure white ink layers strategically to enhance visibility.

Test Printing and Refinement

Send a test print to a sample blank. Observe alignment, color uniformity, edge sharpness, and seam matching. If banding or misalignment appears, fine-tune the tilt angle, laser offset, or artwork distortion and reprint. Slow UV curing slightly if ink shift occurs on extreme curves. Document the validated settings for this cup shape. Once the test print meets your quality standards, your NC-Cylinder Elf-mini Irregularly shaped thermos cup modeling​ workflow is ready for production.

Post-Modeling Care

Clean the fixture and chuck after each run. For stainless steel or glass cups, apply a UV primer before printing to ensure ink adhesion. Recalculate modeling parameters whenever switching to a different cup shape. Use only NOCAI original UV ink and cleaning solution to maintain print quality and warranty coverage.
