๐ How We Collect Data
Our data comes directly from Amazon product listings, collected and verified through a multi-step pipeline:
Search Scrape
Enrichment
Verification
Check
Step 1: Automated Discovery
Our scraper searches Amazon daily for 3D printers, filaments, and accessories across multiple categories (FDM, Resin/SLA, PLA filament, tools & accessories, 3D pens).
Step 2: AI Enrichment
Each product is analyzed by AI (Google Gemini) to extract a clean product name, identify the brand, classify the printer type, and flag low-quality listings. This step has strict anti-hallucination rules โ the AI cannot guess specifications not present in the title.
Step 3: Detail Verification
Individual product pages are scraped to verify the actual brand, extract high-resolution images, current pricing, star rating, review count, and technical specifications.
Step 4: Quality Gating
Products flagged as "junk titles" (e.g., accessory bundles listed as printers, unclear product names) are hidden from the catalogue until verified data is available.
๐ฐ Pricing & Updates
All prices shown are in USD and sourced from Amazon.com. Key pricing details:
- Update frequency: Prices are refreshed daily via our automated scraper
- Discount calculation: We compare the current price against the listed original price to calculate discount percentages
- Price history: Every price update is timestamped so we can show when data was last verified
- Multiple sources: Prices from detail page scrapes always take priority over search result prices
โญ How Scoring Works
Products are evaluated on multiple dimensions. Each score is derived from real product specifications, reviews, and pricing โ never from paid placement.
๐ฏ How Recommendations Are Made
Our "Find My Printer" quiz uses AI to match your answers against our product database:
- Budget: Your price range filters products within that range
- Experience level: Beginners get printers with auto-leveling, easy setup, and good community support
- Use case: Miniatures โ resin printers; functional parts โ FDM printers with high temp materials
Important: Recommendations are based entirely on product specifications and user requirements. We do not accept payment for placement.
