The problem
Anyone who 3D-prints in Brazil — from hobbyists to small businesses — buys filament and resin constantly. The trouble is that prices change all the time and are spread across dozens of shops, and shipping costs vary widely from one region to another. As a result, the "cheapest" offer often turns out expensive once delivery to your door is added, and people waste time hopping from store to store without ever knowing where the real best deal is.
The solution
Melhor Filamento brings offers from many stores into one place and ranks them by total cost — the price plus the estimated shipping to the shopper's postal code. In seconds, people see where they'll pay the least overall, compare brands, colors and material types, and follow each product's price history to know when it's the right time to buy. Those who prefer to pick up in person find the nearest stores on a map. It's all in Portuguese, built for mobile, with a clean and fast experience.
The innovation
The edge isn't "listing prices" — it's comparing the real cost to your doorstep. Most comparison sites ignore shipping, which weighs heavily in Brazil, or treat the entire country as a single place. Here the recommendation changes with the shopper's region: the best deal for someone in São Paulo can be a different one for someone in the Northeast. Add transparent price history and a nearby-pickup option, and you get a smarter buying decision — in a niche, 3D printing, that the big comparison sites serve poorly.
The outcome
A product that's live and working at melhorfilamento.com.br, with its own domain and ready to scale: a catalog of real products, region-aware comparison, a store map and price history. For shops, it's a channel of qualified customers; for shoppers, it's saved time and money with the confidence of paying the best total cost. A solid foundation to become the go-to price reference for 3D printing in Brazil.
