[Hot Item] Premium 3D Printed Engine Model for Display and Education

Basic Info.





1, Preliminary Preparation: Drawing Analysis and Material Selection
Firstly, disassemble the 3D drawings provided by the customer to clarify the form, proportion, and connection logic of each engine component (such as the shape of key components such as cylinder head, turbocharger, intake pipe, etc.).
In terms of material selection, priority should be given to using photosensitive resin (with high printing accuracy and good detail restoration) or PLA (with controllable cost and sufficient toughness), and matching material characteristics based on component complexity - such as using photosensitive resin for fine cylinder head texture and PLA for load-bearing structure.
2, 3D printing: precise restoration of component details
Import the disassembled components into a 3D printer and set high-precision printing parameters (such as layer thickness of 0.05mm and reasonable planning of support structure) to ensure that the contour, hole position, and texture of each component are consistent with the drawing.
During the printing process, it is necessary to process in batches: first print the core components (such as cylinder head and turbocharger body), and then print the auxiliary components (such as intake pipe and bracket) to avoid deformation or jamming caused by one-time printing.
3, Assembly process: Simulate real structural logic
After printing is completed, first clean the supporting structure (lightly handle with tweezers and sandpaper), and then assemble it according to the logic of the drawing:
First, assemble the core modules (such as the snap/threaded connection between the cylinder head and the engine body) to ensure alignment accuracy;
Reinstall peripheral components (such as turbochargers and intake pipes), use micro screws/glue to assist in fixing, and simulate the assembly logic of a real engine.
4, Post processing: coloring and texture restoration
Polishing: Use sandpaper (from coarse to fine) to polish the edges and seams of the components, eliminate printed layer patterns, and make the surface smooth and realistic;
Color separation spraying: Refer to the real color scheme of the engine (such as silver gray for the main body, green for the intake pipe, and silver for the turbine), use a spray pen/air brush to spray in layers, and then apply color after each layer is dry to avoid color difference;
Detail depiction: Use a fine brush to draw details such as heat dissipation holes and bolt textures on the surface of the cylinder head and turbine, simulating industrial texture;
Overall styling: Finally, spray a layer of transparent protective paint to enhance glossiness and durability, making the model feel similar to a real engine.
5, Restoration control: 90% implementation logic
Through the four steps of "structural disassembly → precise printing → logical assembly → detail coloring", from component form to connection logic, from color matching to texture, it closely resembles the real engine in all aspects. for example
The positions of the heat dissipation holes and bolt holes on the cylinder head are matched 1:1 with the actual engine;
The metallic luster of the turbocharger and the green matte texture of the intake pipe are restored through coloring technology;
The assembly clearance and connection method of each component fully simulate the industrial design logic of a real engine.
