Creality sells no newer CFS revision for the K2 Plus as of 2026-09-06 \u2014 the CFS-C is a different unit for the K1 family \u2014 so there is no repeat of the AMS-versus-AMS-2-Pro bundle trap here. ASA_READY = TRUE. This is a T5 inference and here is the reasoning: the machine is enclosed with an ACTIVE chamber heater rated to 60 C, Creality states that 'printing with ABS, ASA, and PPS requires a chamber temperature of 60 C' and lists ASA in the K2 Plus's own supported-filament list, and the machine carries two air filters ('Air Purifier: Yes'). Enclosed AND filtered AND thermally capable, so the test in the schema is met. The CFS itself also lists ASA as supported, so ASA can be run through the color system, not just from the side spool. Caveat worth carrying into any recommendation: 'air purifier' on a consumer FDM machine means an activated-carbon VOC filter, which reduces smell but is not a substitute for ventilation in a shared family home. CF/GF READY NOW, FUTURE-PROOFING COST $0. The stock nozzle is tri-metal with a hardened steel tip, the direct-drive extruder already has hardened steel gears, and Creality lists PLA-CF, PA-CF and PPA-CF as supported. There is nothing to buy later. That is a genuine and underrated advantage against machines that need a $20-$60 hardened kit. MULTI-MATERIAL: the CFS supports water-soluble PVA/BVOH so long as it is dry (Creality explicitly excludes DAMP BVOH/PVA), so soluble-support workflows are possible; no independent test of that was found. It cannot feed TPU at all. WHAT ROB WOULD BE ACCEPTING. Purge waste is the worst in this file: Tom's Hardware measured 207 g of waste plus 17 g of purge tower on a 205 g four-color print. For his actual use \u2014 mostly single-color functional PETG, occasional two-color cosmetic blaster parts \u2014 that is much less punishing than it sounds, because waste tracks the number of color changes, not print size (the same reviewer measured 0.64 g of waste on a two-color job). He would also be accepting a documented bed-flatness problem (ki-creality-k2plus-bed-warp) that owners work around with a 15-minute heat soak, a CFS that jams often enough to have two standard community fixes (ki-creality-cfs-jam), and after-sales support whose reputation is genuinely mixed (ki-creality-support-quality). For a buyer whose stated priority is 'it just works', those three issues are the case against, and they are exactly the kind of thing a spec sheet does not show.

The 'Ghost7+Mcs' bundle ($599) is available:false, no standalone color module is sold anywhere on the store, and OrcaSlicer's FlyingBear bundle contains no multi-material machine variant. No third-party kit is involved. WHY THIS IS UNRANKED RATHER THAN 'SOLD OUT AND STILL SCORABLE' - read this, it is an inference, not a vendor statement: unlike InfiMech, FlyingBear says nothing anywhere about the module's release state; the only hard facts are that the bundle variant is unavailable, that no color module is sold on its own, and that a targeted search on 2026-09-06 found no evidence of a Ghost 7 MCS ever having shipped (the one third-party listing search surfaced, a Ukrainian retailer's 'Ghost 7 + MCS', 404s). The study reads that as the same unshipped ColorBox/MCS module InfiMech states in writing is 'not yet available for purchase' on the shared-hardware EX, and therefore as no first-party multi-color path rather than a temporary stock-out. THE ALTERNATIVE READING AND WHAT IT WOULD COST: if the Ghost7+Mcs is in fact a shipped SKU that is merely out of stock, then under 00_BRIEF INCLUDE_PREORDER it would be a scorable sold_out configuration at $599 pre-tax, $636.44 all-in at 6.25 percent with the store's current $0.00 shipping, or $742.69 if the published $100 US freight band applies ($699 pre-tax). Re-check the variant before any final ranking. SHIPPING - READ THE CAVEAT: FlyingBear's checkout returned 'Free shipping' $0.00 for zip 02420, Massachusetts, with the Ghost7-Global variant in a live cart, so $0.00 is what the store says today. But FlyingBear's own published rate table charges $100.00 to the US for anything in the 8.11-16.49 kg band and only makes 0-7.50 kg free, and the Ghost 7 variants carry a shipping weight of 0 g in the store - a 250x250x205 CoreXY machine is not under 7.5 kg (the equivalent InfiMech listing declares 14 kg). Budget for the possibility that this becomes $100, which would take the configuration to $636.19 all-in. Ships from China: the Ghost 7 is absent from FlyingBear's local-warehouse table, and the policy's China route is 'about 15-20 days' plus 2-3 days to process, with import taxes on the buyer. asa_ready = false (T5 inference, stated per 02_SCHEMA sec.4): the ChuchaTV3D walkthrough (2026-05-31) shows the machine open on both sides, no filtration accessory is sold for it, and no vented-enclosure accessory exists in the vendor's catalog. In a shared family home this is the disqualifier, before price is even discussed. pla_petg_ok = true is carried from the 110 C bed confirmed on camera and from the identical InfiMech EX hardware, but note that no independent PETG test of a Ghost 7 exists - treat it as weaker evidence than the EX's. abrasive_ready_now is left null because the Ghost 7's stock nozzle material could not be established from any source; abrasive_ready_with_upgrade is true because a hardened-steel hotend is listed as a cheap first-party part, although it is currently out of stock.", "_file": "imports.json" }, { "id": "cfg-formbot-troodon-mini250-boxturtle", "printer_id": "formbot-troodon-2-0-pro-mini-250", "addon_ids": [], "label": "Formbot Troodon 2.0 Pro Mini 250 (pre-assembled, out of stock, bare printer - no first-party multi-color path)", "mmu_sku_in_combo": null, "is_refurb": false, "is_kit": false, "assembly_hours_est": 3.0, "cost_items": [ { "item": "Troodon 2.0 Pro Mini 250MM pre-assembled CoreXY", "usd": 599.0, "source_id": "src-formbot-troodon-mini", "note": "Everyday price; former price 699.00 USD.

Four colors, a fully enclosed CoreXY, Klipper, no account, no cloud, no filament DRM, and a design nobody can revoke. On openness alone it wins outright. ASSEMBLY: 30 HOURS, AND THAT IS ONLY THE PRINTER. assembly_hours_est of 30 comes from two independent sources and covers the printer alone. CNC Kitchen's build report says 'Budget 20 to 40 hours for the build' and warns you will work through five separate manuals. The Team FDM thread has five or more owners reporting a week at 3 to 4 hours a day, three weekends, or a month of evenings, with one saying plainly 'for a first-time builder I would suggest you take your time and expects to put in 30-40hrs'. CNC Kitchen's closing line is the one to weigh: if you cannot 'afford to spend 50, 100 or even more hours to build and tune it', buy something pre-built. Building the BoxTurtle is ON TOP of that and is not included in the 30 hours. No sourced figure for it was found; that gap is flagged in unverified as boxturtle_assembly_hours. AND ON TOP OF THAT. You must print the FilamATrix toolhead cutter parts yourself, which is only possible after the printer works; install the AFC-Klipper-Add-On with root access on the CB1; and tune either toolhead cutting or tip forming. ArmoredTurtle states BoxTurtle 'works most reliably with a toolhead filament cutter'. Formbot buyers also report there is no ready-to-use firmware configuration - see ki-formbot-voron24-docs-config-gap. For a buyer who is not fluent in any programming language, this is the risk that matters more than the price. asa_ready is FALSE and this is the T5 inference behind it: the machine is enclosed by design, but there is no established filtration. AUDIT 2026-09-06: the printer's filtration field read 'carbon' and is now null. Formbot's page and spec table never mention an enclosure, a filter, carbon or a Nevermore; the 'carbon' value came from a [fan_generic nevermore] stanza in Formbot's stock printer.cfg, which names a fan output rather than proving a carbon filter is in the box, and Formbot's Voron 2.4 spare-parts collection sells no filter SKU (re-fetched 2026-09-06). The only owner report about a filter, dated 2026-07-16 on Formbot's own page, reads 'remove the back filter. It doesn't do anything. Only if you mod it to use a special HEPA filter.' For a printer living in a shared family room, an enclosure plus a filter of unknown type that one owner calls useless is not a documented safe-venting path. Budget for a Nevermore rebuild or a vented location; no price for that was captured. abrasive_ready_now is false: the stock nozzle is 0.4 mm of unstated material and Formbot does not say the extruder gears are hardened. The upgrade is a hardened nozzle and possibly hardened gears, cheap in absolute terms, but no sourced US price was captured, so future_proofing_cost_usd is null rather than a guess. SHIPPING IS NOT IN THIS TOTAL. shipping_usd is null, not zero. Formbot publishes no shipping policy anywhere on formbot3d.com - its only company page carries contact details - and the cost is revealed at checkout.

Everything new, everything first-party, standard 12-month warranty, fits the 1,300 USD all-in budget with about 57 USD of headroom.\n\nShipping is 0.00 and that is a measured figure, not an assumption: a live Shopify shipping-rate query for a cart containing exactly these items, to ZIP 02138 in Massachusetts, returned one rate - 'Phrozen Free Shipping' at 0.00 USD (src-phrozen-us-cart-shipping, 2026-09-06). Phrozen's published shipping policy does not state a free-shipping threshold, so this was established by querying rather than by reading. The store quotes a standard lead time of about one week and ships to the mainland United States only, which covers Massachusetts.\n\nMmu_sku_in_combo is not a guess: this is not a bundle, it is two separately priced line items, and the SKU on the Chroma Kit line is 51030029901012 read straight out of the Shopify variant record and re-confirmed in the cart response.\n\nWhat you are buying for that money, stated plainly: excellent open-source credentials (published Klipper, Moonraker and Orca forks), a large 300 mm cubed build volume, good single-material PLA and PETG results in two independent hands-on tests - and a multi-color system that both reviewers and owners describe as unfinished, with purge behavior that owners still complained about in August 2026 on the newest firmware, no way to tell the printer what color is in which slot, and feed timeouts that get worse with third-party spools. The Chroma Kit also has to be mounted on brackets you print yourself if you do not also buy the PentaShield.\n\nasa_ready = FALSE. This is a T5 inference and here is the reasoning, per 02_SCHEMA section 4. The test is 'enclosed AND filtered, or a documented safe-venting path'. The Arco is an open-frame machine and this configuration contains no enclosure at all, so 'enclosed' fails outright. Adding the 150 USD PentaShield would not rescue it either, because that enclosure is not sealed: independent testing found a large opening at the rear of the lid, the permanently open purge-waste chute in the floor of the printer, and - once the Chroma Kit is fitted - an acrylic lid panel that has to be removed entirely to pass the filament tubes through (ki-phrozen-pentashield-not-sealed, T2, 2026-01-15). An activated carbon filter above an enclosure with an open hole in its floor is not fume containment, and no safe-venting path is documented anywhere in Phrozen's materials.\n\nStated precisely, because the audit pass found the earlier wording overstated it: the same reviewer's ABS prints were poor, but he explicitly attributed that to 'poor extrusion, which points to profile problems rather than a fundamental hardware limitation', and said it 'didn't look like classic enclosure or temperature issues either'. The poor ABS is therefore evidence about Phrozen's slicer profiles, not about the enclosure; the containment argument stands on the physical gaps alone, which is enough.\n\nOne vendor conflict is recorded rather than resolved: the Chroma Kit product page lists ASA under DRYING only and NOT under PRINTING, while the Arco product page's own 'Works with Chroma Kit' block lists ASA under both drying and printing. Phrozen's two pages disagree about whether multi-color ASA is even a claimed capability, so no weight is put on either. Independently of that, the Arco spec sheet handles ABS/ASA-class materials only with the words 'recommended to print with the PentaShield'. For a printer that has to live in a shared family home, treat this machine as a PLA/PETG machine.\n\nmulti_material_ready is left null rather than guessed. Tom's Hardware's 2024 announcement said the Chroma Kit would allow dual-material printing such as PLA with PETG for easy-release supports, but no Phrozen documentation of a support-interface or multi-material workflow was found on 2026-09-06, and the Chroma Kit's own automatic switching is documented as working only 'between filaments of the same color and material'.", "_file": "phrozen.json", "scores": { "just_works": { "score": 2.5, "evidence_sufficient": true, "rationale": "The multi-color unit, which is the whole point of this configuration, is described as unfinished by both independent testers and by owners: feed and retraction timeouts that made longer multi-material prints impossible with third-party spools, purge behavior that owners were still complaining about in 2026-08 on the newest firmware, and no way at all to tell the printer which color or material is in which slot.

Its 70 C dryer has no vents, so moisture driven out is reabsorbed the moment the heater stops; feed and retraction timeouts are common, with one reviewer's channel simply not working and another getting repeated timeouts on any third-party spool; and it only accepts spools 50-60 mm wide.

Corrected during the audit pass, because the earlier wording had the direction of the comparison backwards. Like for like against the all-new direct configuration it is CHEAPER: 1,099.99 vs 1,170.00 pre-tax, 1,168.74 vs 1,243.12 all-in, a saving of 74.38 USD, and both routes ship free. It is dearer only than the outlet route, by 28.99 USD pre-tax (1,099.99 vs 1,071.00) - and that route buys an open-box multi-color unit with a 3-month warranty, so the comparison is not like for like. Note also that the seller of record on both Amazon ASINs is 'Phrozen 3D Printer', Phrozen's own storefront, so this is Phrozen selling through Amazon rather than an independent reseller. Its non-price advantages are Amazon fulfilment (delivery quoted five days out, versus about a week of lead time direct) and Amazon's 30-day refund/replacement window against Phrozen's 13-day refund window.\n\nSHIPPING IS UNVERIFIED here and is recorded as null rather than assumed to be zero. The standalone Arco listing says 'FREE delivery Friday, September 11'; this bundle listing's delivery line omits the word FREE. The arithmetic below therefore treats shipping as zero, which may understate the true cost. Also unresolved: the listing carries a '-15%' discount badge while the list and sale prices are identical, so whether 1,099.99 is promotional could not be established.\n\nStock is thin - three units - so this price and this availability should be re-checked before relying on either.\n\nasa_ready = FALSE. This is a T5 inference and here is the reasoning, per 02_SCHEMA section 4. The test is 'enclosed AND filtered, or a documented safe-venting path'. The Arco is an open-frame machine and this configuration contains no enclosure at all, so 'enclosed' fails outright. Adding the 150 USD PentaShield would not rescue it either, because that enclosure is not sealed: independent testing found a large opening at the rear of the lid, the permanently open purge-waste chute in the floor of the printer, and - once the Chroma Kit is fitted - an acrylic lid panel that has to be removed entirely to pass the filament tubes through (ki-phrozen-pentashield-not-sealed, T2, 2026-01-15). An activated carbon filter above an enclosure with an open hole in its floor is not fume containment, and no safe-venting path is documented anywhere in Phrozen's materials.\n\nStated precisely, because the audit pass found the earlier wording overstated it: the same reviewer's ABS prints were poor, but he explicitly attributed that to 'poor extrusion, which points to profile problems rather than a fundamental hardware limitation', and said it 'didn't look like classic enclosure or temperature issues either'. The poor ABS is therefore evidence about Phrozen's slicer profiles, not about the enclosure; the containment argument stands on the physical gaps alone, which is enough.\n\nOne vendor conflict is recorded rather than resolved: the Chroma Kit product page lists ASA under DRYING only and NOT under PRINTING, while the Arco product page's own 'Works with Chroma Kit' block lists ASA under both drying and printing. Phrozen's two pages disagree about whether multi-color ASA is even a claimed capability, so no weight is put on either. Independently of that, the Arco spec sheet handles ABS/ASA-class materials only with the words 'recommended to print with the PentaShield'.

The poor ABS is therefore evidence about Phrozen's slicer profiles, not about the enclosure; the containment argument stands on the physical gaps alone, which is enough.\n\nOne vendor conflict is recorded rather than resolved: the Chroma Kit product page lists ASA under DRYING only and NOT under PRINTING, while the Arco product page's own 'Works with Chroma Kit' block lists ASA under both drying and printing. Phrozen's two pages disagree about whether multi-color ASA is even a claimed capability, so no weight is put on either.

Tom's Hardware's 2024 announcement said the Chroma Kit would allow dual-material printing such as PLA with PETG for easy-release supports, but no Phrozen documentation of a support-interface or multi-material workflow was found on 2026-09-06, and the Chroma Kit's own automatic switching is documented as working only 'between filaments of the same color and material'.\n\nSTOCK IS ONE UNIT.

The enclosure is also physically large: the MK4S alone is already 500x550x400 mm. shipping_usd is null and flagged unverified: Prusa's Terms (art. 8.5) say transport is charged separately and depends on destination and method, and no rate card is published anywhere on the site or in the knowledge base. The e-shop's own cart string, live on the product pages on 2026-09-06, reads 'Add the Assembled Original Prusa CORE One or MK4S and get a free shipping!', which points to free carriage on an assembled CORE One or MK4S and says nothing about kits or bare add-ons.

Prusa sells the MK4S, the MMU3 and the Original Prusa Enclosure as one bundle SKU at $1,389, against $1,537 for the same three products bought separately. Over the $1,300 budget, inside the $1,600 stretch at $1,475.81 all-in. asa_ready is FALSE here on purpose: Prusa's own MK4S spec row names the enclosure AND its filtration add-on together as the precondition for ABS/ASA/HIPS/PA, and this bundle does not include the filtration - add $82.99 and you get cfg-prusa-mk4s-mmu3-enclosure-bundle-filtration, which still fits the stretch. The enclosure is supplied as a kit and is physically large: the MK4S alone is already 500x550x400 mm.

THE PHASE 0 FIGURE WAS MISLEADING AND THIS IS THE CORRECTION. The coverage audit recorded this machine as 'V-Core 4.1 (US kit) 1035.29', which reads as an in-budget candidate. It is not. That figure buys the mechanical kit alone; a working V-Core 4.1 needs the 768.56 USD electronics kit on top, which puts the bare single-toolhead machine at 1916.17 USD all-in before any multi-color capability. This correction is the most important thing this record contributes. ASSEMBLY: 28 HOURS, MEASURED. Summed from Pascal Riesinger's section-by-section timed build log of a V-Core 4 in exactly this IDEX configuration: frame 4h15, Z axis 2h15, Y rails 15min, hybrid motion 2h, X axis 1h30, bed 5min, IDEX toolhead 3h30, gantry alignment 10min, accessories 2h, electronics 10h, hybrid and IDEX Y belts 30min, IDEX accessories 1h30. That excludes commissioning, excludes the enclosure section he skipped, and is one experienced builder's time on the 4.0 rather than the 4.1. Ten of the twenty-eight hours are the electronics section, which he calls 'by far the most time-consuming and frustrating'. asa_ready is FALSE and not marginally. Rat Rig does not sell enclosing panels for this machine at all, only DXF files to have your own cut. An unenclosed printer cannot do ASA acceptably in a shared family room whatever filter is bolted to it, which is why the Rat Pack filter addon is captured but not costed into this configuration. abrasive_ready_now is true and the future-proofing cost is 0 USD - the T1 spec table lists a hardened steel 0.6 mm nozzle in the box and a materials list running to PA6-CF, PPA-CF and PET-CF. This machine is the best equipped in this file for fiber-filled filament and the least affordable. SHIPPING AND DUTY ARE NOT IN THIS TOTAL, AND BOTH ARE REAL.

The rule is 'enclosed AND filtered, or a documented safe-venting path'. The bare U1 is only partially enclosed (sides, rear cover, front glass door, open top) and has NO filtration of any kind. Snapmaker's own supported-materials table lists ASA and ABS only under 'With Optional Top Cover'. There is no documented safe-venting path for the bare machine. Two reviewers did print ASA/ABS successfully without the cover - Tom's Hardware ran PolyLite ASA on the open machine and PCMag printed an ABS bracket using a DIY lid - but 'a reviewer got it to work' is not a safe-venting path in a shared family home with people in the room, and one Reddit owner's first ABS print detached, blobbed and bent a nozzle. So: false, deliberately.\n\nMULTI-COLOR: first-party and included, not an add-on. Four toolheads, roughly five-second changes, and independently measured purge waste in single-digit grams per plate rather than the tens of grams an AMS-style purge produces (see the printer record's measured_speed_notes and notes). Ceiling is four colors.\n\nMULTI-MATERIAL: multi_material_ready is true on documented evidence, not inference - Snapmaker documents PVA and breakaway support workflows, Tom's Hardware printed PLA with Polymaker CoPE breakaway supports, and PCMag printed PLA against TPU and separated the parts cleanly.\n\nCF/GF: not ready as sold (plain stainless hot ends). $49 buys four hardened hot ends, which is the entire upgrade; no hardened extruder part is sold or listed as needed. Snapmaker's table pairs CF/GF with the top cover as well, but 3DPrint.com printed PETG-CF/GF and PA6-CF with hardened hot ends and no cover.\n\nWHAT THIS CONFIGURATION IS NOT: it is not the ASA machine, and at RUN_DATE there is no scorable ASA configuration of the U1 at all. The only first-party route to an enclosed, filtered U1 is the Top Cover, and on 2026-09-06 that accessory is badged 'Pre-Order' on us.snapmaker.com ('The U1 Top Cover is now available for pre-order'), with Snapmaker's own wiki giving an estimated ship window of November 01-15, 2026 and estimated delivery of November 15-30, 2026 for official-store orders placed after 2026-01-13; even the earliest Kickstarter tier only reaches the US warehouse on September 01-05, 2026, so no customer has one yet. A U1 + Top Cover configuration therefore fails hard filter (a) - purchasable AND deliverable new in the US at RUN_DATE - and is excluded outright by INCLUDE_PREORDER, so it was removed from configurations[] in the 2026-09-06 audit rather than left in the file to be ranked as if it were buyable. Nothing is hidden by that removal: the accessory keeps its own priced record (addon snapmaker-u1-top-cover, $149, with its filtration, chamber and noise specs and their vendor caveats) and its own dated census entry (ki-snapmaker-u1-top-cover-backorder).
