Price check: Elegoo Mars 4 Ultra dips below $220 as Centauri Carbon and M7 Pro rise
The Elegoo Mars 4 Ultra fell 19.7% to $219.99 this week, while the Centauri Carbon and Photon Mono M7 Pro both climbed double digits.
What moved this week
The biggest mover is the Elegoo Mars 4 Ultra, down 19.7% in seven days from $273.92 to $219.99 — a solid drop for a resin printer, and a good window if you have been waiting to pull the trigger.
Two machines moved the other way. The Elegoo Centauri Carbon rose 16.2%, from $258.18 to $299.98, and the Anycubic Photon Mono M7 Pro climbed 11.8%, from $402.32 to $449.99. If either was already on your shortlist, the lower price is gone for now — we would wait for the next dip rather than chase.
What it means for buyers
Swings like these are normal. A single sale or a retailer reverting to list price can produce double-digit percentage moves on a $250–$450 machine. The practical takeaway: treat a sharp drop as your cue to act, and treat a spike as a reason to hold.
Our tracker now follows 32 printers, with recent additions including the Sovol SV08 ($549), the FlashForge AD5X ($349), and pro-grade machines such as the Formlabs Fuse X1 ($84,999). We will flag the next meaningful moves as they happen.
