Our Story

We think that making music should be accessible to everyone. Our team of dedicated 3D-engineers, printers, professional musicians, and teachers is committed to creating affordable musical instruments and equipment through resin and FDM based printing. After connecting in Houston, we united with friends across the country to ensure that the joy of music can be enjoyed by all, regardless of budget.

Elevating Brass Performance:

EggWin RezTone SLA Resin Mouthpieces

At EggWin, we craft our RezTone mouthpieces using Stereolithography (SLA), a precision liquid polymer resin process that produces superior custom components for discerning brass players. Unlike the mass-produced thermoplastics offered by major manufacturers, our hand-finished RezTone mouthpieces deliver a premium alternative that prioritizes acoustic nuance, player comfort, and personalization.

Traditional plastic mouthpieces, typically made via high-volume injection molding, often feel lightweight, flimsy, and acoustically generic. In contrast, RezTone resin mouthpieces offer a denser, more substantial feel in the hand and on the embouchure. Players frequently describe them as more satisfying and "serious" to play, with better perceived stability and response.

Our 2025 spectrographic studies (Orion Project) comparing resin to traditional brass demonstrated that RezTone produces smooth, consistent waveforms and balanced harmonic distribution. They rival metal in overall tonal quality while providing surprising evenness and stability.

SLA resin excels where mass-produced plastics fall short: unmatched design freedom for custom geometries, rim profiles, cup depths, and throat dimensions tailored to individual players or specific musical demands. Players with metal sensitivity and advanced players seeking optimization benefit from material tailoring that enhances comfort during extended sessions, reduces fatigue, and delivers acoustic subtlety difficult to achieve economically at scale with thermoplastics.

What truly sets EggWin apart is our fully handcrafted approach. From initial design through SLA printing to specialized post-processing, every mouthpiece receives meticulous attention. This enables complete customization: unique colors, personalized text, logos, and bespoke geometries unavailable from large-scale producers. The result is a high-end, artisanal product that transforms a functional accessory into a personalized extension of the musician’s voice.

EggWin RezTone mouthpieces represent the best of modern manufacturing and traditional craftsmanship and offers brass players superior feel, performance consistency, and individuality without compromise. For those ready to move beyond ordinary plastic or traditional metal, RezTone delivers a refined, player-centric experience.
