# Thingiverse MakerWorld | 3Drop vs Scrap Science

The clearest difference is monetization model: Scrap Science at free with in-app purchases against Thingiverse MakerWorld | 3Drop's subscription. Scrap Science also leads on ads (none vs shown) and review sentiment (100% vs 79%). Thingiverse MakerWorld | 3Drop's advantage is rating (4.8 vs 4.3) and ratings volume (365 vs 3). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Thingiverse MakerWorld | 3Drop sells 5 in-app purchases, starting at $1.99 per month and Scrap Science sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Thingiverse MakerWorld | 3Drop holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Thingiverse MakerWorld | 3Drop has 365 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 79% of Thingiverse MakerWorld | 3Drop's written reviews are positive against 100% of Scrap Science's, so the app with the better star average is not the one people write more warmly about.

Thingiverse MakerWorld | 3Drop ships an update every 9 days, Scrap Science every 2 weeks. The most recent releases landed on September 25, 2026 and June 11, 2026 respectively.
