LONGER ePrint

Full research callouts (16 shared across configurations)

• New: Ship window slipped again — the official product page now reads roughly "end of September" 2026, past the earlier mid-September target, and the listing is still [Pre-order] with no delivery confirmation. Kickstarter funding totals reported with a source conflict preserved (not averaged): the campaign header shows ~$4,294,357 / ~1,621 backers, while the close post shows ~$4,094,537 / ~1,540 — the gap is consistent with post-close late pledges. Still no delivery notice as of 2026-08-31. (longer3d.com product page; Kickstarter campaign, captured via browser)
• New: Shipping slipped again — the official product page now reads "estimated shipping from the mid-September," past the earlier end-of-August 2026 target, and the listing is still labeled [Pre-order] with no delivery confirmation. (longer3d.com product page)
• New: Still zero independent post-shipping hands-on coverage. Newest-first YouTube and web search return only launch-window (Oct 2025–Apr 2026) affiliate/seeded reviews, reseller/affiliate comparison pages, and manufacturer content — no owner unboxing or delivered-unit report on any reachable channel. The absence is itself the finding. (YouTube, DuckDuckGo)
• New: Live store pricing is muddier, not settled — the dual-head listing's og:price reads $1,699 (below the $1,899 campaign figure), with a $2,499 variant; treat retail price as an unconfirmed range. Kickstarter shows 8 updates / 1,860 comments (active engagement), but update titles are JS-rendered and could not be read, so whether any is a shipping notice is unconfirmed.

• New: Campaign fulfillment is now estimated for the end of August 2026. This is a revised estimate after the earlier June target passed, not confirmed delivery.
• New: Five CUPP owner-test videos show a physical ePrint unit producing high-relief, multi-pass, embossed, and flat full-color jobs. A flat pet-photo recording runs about 6.7 minutes, but substrate size and quality mode are not yet controlled for cross-brand comparison.
• New: Video review found mild visible banding in flat or low-detail color areas on two samples. Confidence is low-to-moderate because this is visual footage analysis without a measurement target.
• New: Relief-height evidence remains contradictory: the current claim is 15mm, an official test demonstrates 22mm, and early promotion claimed 60mm. CUPP preserves all three dated values.
• Not shipped as of Jul 24, 2026 — every spec here is manufacturer-sourced; no independent reviewer, Reddit owner, or teardown exists.
• Software currently supports only JPG/PNG — no TIFF/PSD/AI/CAD support yet, per the maker's own FAQ.
• Printhead warranty is only 3 months (vs. 1-year machine warranty); switching to third-party ink requires manual recalibration and a full flush.
• No published safety/VOC certification for the open ink system, unlike eufyMake's GREENGUARD Gold-certified ink.
• REDDIT FLAG (r/UVprinting, unverified rumor): a commenter who says they've seen the machine live claims it may actually ship with proprietary cartridges like eufyMake, contradicting the "open tank, third-party ink" marketing that's the machine's main selling point — worth confirming before buying on that basis alone.
• An experienced UV-printing commenter (r/UVprinting) states desktop UV printheads generally last only 6–12 months regardless of usage, and that small desktop UV printers as a category are "an unmanageable amount of maintenance vs. the volume of work they can do" — useful category-wide context, not Longer-specific.
• One backer is already reselling their All-in-One Combo slot (paid $2,949) to switch to the xTool O1 Omni instead — not a quality complaint (they cite already owning an xTool laser), but a sign of some early-backer churn toward the competing xTool launch.
• New(Facebook, Longer ePrint Kickstarter Backers group): backer skepticism is rising further — multiple backers in the same thread question whether the product exists at all, citing continued silence from Longer while competitors post active video content. A sentiment signal, not a spec change, but worth watching for a phase shift toward an actual shipping update.
