Simulated piano model manufacturer

1、 Material selection: Simulate the visual and tactile experience of a real piano

Main frame material

Using matte textured resin to print the piano body, this material can perfectly present the subtle reflective characteristics of the piano paint surface, while avoiding the cheap reflective feeling of ordinary PLA plastic

The piano keys are printed separately using black and white dual color resin, and the black keys are enhanced with carbon fiber containing dark gray resin for texture contrast

Detail enhancing materials

The sheet metal components are made of copper plated PLA material, and the aging effect of brass is simulated through post oxidation treatment

The strings are hand assembled with 0.3mm diameter phosphor bronze wire, which can maintain visible tension even at a size of 20cm

2、 3D Printing Technology: Balancing Accuracy and Art

Split printing strategy

Disassemble the model into 12 core components (piano cover, body, keyboard cover, pedal system, etc.), with the minimum printing component being a 1.2mm music stand support foot

Using a 0.08mm layer height to print key curved areas, achieving a smooth transition of the piano body curve

Special structural treatment

The piano keys adopt a movable design, achieving a simulated pressing sensation of 3mm stroke through a micro hinge structure

The open piano cover is printed with proportional soundboard texture inside, and even when zoomed in to 20cm, the wood texture direction can still be seen

3、 Post processing: The Transformation from Mechanical Components to Artworks

Four step method for surface finishing

Fill the layer pattern: Fill the joint with UV resin, and after UV curing, polish it with 800 grit sandpaper

Primer treatment: After spraying gray primer, use a cotton pad dipped in graphite powder to wipe the protruding wood texture

Piano paint simulation: alternate spraying of 5 layers of semi gloss varnish and black matte paint, imitating the unique "deep pool" paint effect of a grand piano

Metal parts aging: Dip a cotton swab in copper green solution and apply it to the pedal hinge to create natural oxidation marks

Detail enhancement process

Hand draw the brand logo with a 000 pen and complete a 0.5mm size hot stamping lettering under a microscope

Draw ivory cracks on the side of the piano keys with a pencil, imitating the natural aging characteristics of antique pianos

The internal soundboard is pasted with imitation parchment phonetic symbols, which appear and disappear through the gaps between the strings
