South Heaven Gate Project: “Xuan Nu” Aerospace Fighter—One-Piece White Coating Printed

The “Xuan Nu” aerospace fighter, as the core combat unit of the South Heaven Gate Project, is a stealthy aerospace platform designed for penetration strikes and information sensing-. Its appearance is strikingly futuristic, featuring a diamond-shaped blended wing-body configuration with edge-aligned stealth design, along with large, hollowed-out meson ring flow generators on both sides paired with forward-swept wings, creating a powerful visual impact-.

Now you can bring it to life with 3D printing. Even better, if your 3D printer supports multi-color material switching (such as AMS), you can directly print an all-white “Xuan Nu” with a perfect sci-fi aesthetic—no post-print painting required. The white coating best highlights its sleek, streamlined fuselage and futuristic look, and since it’s printed in one piece, there’s no need for time-consuming painting afterward.

🚀 Key Highlights

• Faithful Reproduction with Maximum Tech Appeal: This model precisely replicates the sci-fi exterior of the “Xuan Nu” aerospace fighter, complete with its感应式力场驱动装置 and variable-cycle engine, enabling it not only to operate within the atmosphere but also to carry out missions beyond the atmosphere-. The model perfectly captures this design, with sharp edges and a distinctly futuristic feel.

• One-Piece Printing, No Assembly Required: The fuselage has been optimized for 3D printing, allowing it to be printed as a single, seamless part—no tedious assembly of individual components, so you can start playing right away.

• Smart Supports, Easy Removal: The model is meticulously designed with minimal support structures. Some users have commented, “You can even print it without any supports,” and the designer recommends, “Just use the automatic tree-like support setting”-1. You no longer need “skillful hands” or “miraculous pliers” to wrestle with supports.

• Efficient Printing, Quick to Master: Taking the common 0.28mm layer height as an example, a full print takes only about 4 hours, with low material consumption—making it a fun weekend project that can be completed in a single session-. Of course, you also have plenty of room to experiment with other settings.

🛠️ Printing Notes

• Model Information: Fuselage length 300mm, fuselage width 190mm, and overall height (including base) 150mm-. We recommend using PETG material, as its toughness and precision better reproduce complex features like the fuselage edges.

• Recommended Settings:

  • Default Setting: Layer height 0.28mm, 2 wall layers, 10% infill, no supports-9. Ideal for quick prototyping when speed is priority.

  • High-Quality Setting: Layer height 0.12mm, 3 wall layers, 15% infill, and select “automatic tree-like supports”-1. Perfect for static displays that demand extreme detail, fully showcasing the “Xuan Nu’s” sharp lines and futuristic vibe.

• Estimated Print Time: About 4 hours at 0.28mm layer height, or 3.2 hours at 0.12mm layer height for a single-piece print--1.

• Special Note on White Coating: If you want to achieve an all-white finish directly, there are two options:

  1. Use White Filament: Simply print with white PLA or PETG filament, and the finished model will be completely white.

  2. Suspend Filament Change: If you’d like to add white coloring to parts like the wings or missiles, set a filament-change pause point in your slicing software. When the print reaches that layer, switch to white filament to continue printing, achieving a localized two-tone effect.

⚡ Frequently Asked Questions and Optimization Tips

• Parts Don’t Match or Assembly Is Too Tight: Different filaments have different shrinkage rates, which can lead to fitting tolerances-1. We recommend pre-assembling before applying adhesive; if it’s too tight, gently smooth the joints with a small knife or file.

• Model Warping: If the bottom edge of the model lifts up, apply a thin layer of solid glue or anti-warping adhesive to the heated bed before printing to improve first-layer adhesion-71.

• How to Optimize the White Finish: If the white filament doesn’t produce the desired result, consider following post-print painting techniques: first apply a light primer (light gray or white) to even out the base color, then apply the main color. This effectively prevents uneven coloring or color reversal-.

• Enhance Overall Detail: Try the high-quality 0.12mm layer height setting combined with a moderate-to-low printing speed of around 150mm/s to better highlight intricate details like the fuselage edges.
