Short answer: the 500 ml kit is $370.99 under SKU CXY02.01.0341, the 1000 ml kit is $520.99 under SKU CXY02.01.0227, and the 1000 ml spiral-feeding version is $540.99 under SKU CXY02.01.0248. The listing prices the capacity directly: the 500 ml barrel holds 1 kg of clay mud, and the 1000 ml barrel holds 2 kg of clay mud. The per-kilogram arithmetic from the listing prices works out to roughly $261 per kilogram on the 500 ml kit and roughly $260 per kilogram on the 1000 ml kit, computed directly from the kit figures.

The honest note before the tables: the 57 Motor Line Style and Aviation Connector versions fit the Moore 1, Moore 2 Pro and Moore 3 Pro, while the Spiral Feeding version adds the Moore X Series as the more powerful model. The seller has not published the motor specifications, the thrust or torque, the connection length, the internal spiral structure, or the full kit component list, so those fit details are merchant-confirmation items with store support before a cross-machine purchase.

This guide keeps the three variants beside each other on the same questions: which capacity fits the run, which model fits the machine, how the feeding method differs, how the kit cleans, and which version a studio or classroom should stock. All Tronxy pricing figures are fixed store prices on the QIDI Tech listing; competitor and ecosystem material notes are labeled as general practice or machine context, because feeding-system pricing and practice change by brand and region.

The scope of this guide is the barrel kit itself. It does not cover the nozzle, the removable bed, or a full continuous-production feeder. General clay rules apply to every variant: de-air the clay on loading, match the body consistency to the putter, and wash the barrel in warm water with a soft brush between bodies. The machine context behind the kit is the Moore platform: the Moore 1 runs replaceable adjustable synchronous feeding at 40 mm/s with an electric push rod replacing the air compressor, the Moore 2 Pro runs LDM extrusion on OSG dual-core rails, and the Moore 3 Pro runs electric push rod and screw extrusion.

Before the tables, the eight comparison questions used through this article. Each narrows the choice for a specific buyer: a Moore 1 owner, a Moore 2 Pro owner, a Moore X user, a classroom, a studio, or a maker comparing feeding methods.

1. Which capacity fits the run? The 500 ml kit holds 1 kg of clay mud per barrel; the 1000 ml kit holds 2 kg per barrel, per the listing. A small vessel run finishes on the 500 ml barrel; a long vessel run steps up to the 1000 ml barrel without a mid-run refill.

2. Which model fits the machine? The 57 Motor Line Style and Aviation Connector versions fit the Moore 1, Moore 2 Pro and Moore 3 Pro. The Spiral Feeding version adds the Moore X Series as the more powerful model. The Aviation Connector is the aviation-plug connection for newer machines; the 57 Motor Line is the 57 motor line connection.

3. What does the feeding method change? The electric putter drives the barrel's push rod with adjustable synchronous feeding. The Spiral Feeding version adds the screw family: general clay-extrusion research treats the screw as steady for stiff clay bodies, and the spiral version is the more powerful model.

4. Per-kilogram math: the listing prices the kit directly. The arithmetic from the listing prices works out to roughly $261 per kilogram on the 500 ml kit at $370.99 per 1 kg barrel, and roughly $260 per kilogram on the 1000 ml kit at $520.99 per 2 kg barrel, computed directly from the kit figures.

5. Cleaning and maintenance: the listing's guidance calls for removing the nozzle and the feeding-system residue, washing with warm water and a soft brush, and drying before reuse. The barrel is replaceable, so a second body swaps in while the first washes.

6. Air supply: the electric putter runs on the machine, and the Moore path does not require an air compressor. The machine context notes the Moore 1 electric push rod replaces the air compressor, while the Moore 3 standard offers an air-control-valve mode.

7. Wear and upgrade path: a barrel that no longer seals, a putter that stalls, or a feed path that needs more power steps the buyer up to the 1000 ml or spiral version. The motor specs and spiral internals are merchant-confirmation items before the upgrade.

8. Cross-machine fit: the kit is designed for the Moore Series, and the model list is the compatibility source. The seller has not published the full kit component list, so cross-machine buyers confirm with QIDI store support before purchase.

The Tronxy barrel kit lists at two fixed prices on the QIDI Tech listing. The table below prices each capacity, lists the SKU and the clay weight it holds, and matches the capacity to the run type. All figures are product facts from the listing; the per-kilogram arithmetic is computed from the kit prices; the run-type matching is working practice.

The capacity table reads as one slope: the 500 ml kit at $370.99 holds a 1 kg barrel for small runs, the 1000 ml kit at $520.99 holds a 2 kg barrel for long runs, and the 1000 ml spiral version at $540.99 adds the more powerful screw feeding path. The two 1000 ml variants hold the same 2 kg barrel; the spiral version differs in the feeding method and the machine list. A classroom stocked with small vessels runs the 500 ml kit; a studio running long vessels steps up to the 1000 ml barrel.

The table below compares the three model variants on the questions a buyer actually checks: connection type, machine list, feeding method, and the buyer type each suits. The Tronxy figures are product facts from the listing; the feeding-method notes are general practice and ecosystem context, labeled as such.

The model table's standout row is the machine list: the 57 Motor Line and Aviation Connector versions fit the Moore 1, 2 Pro and 3 Pro, while the Spiral Feeding version adds the Moore X Series. The second decisive row is the feeding method: the spiral version adds the screw family, which general practice treats as steady for stiff clay bodies. A buyer who orders by capacity alone may order the wrong connection; a buyer who matches the model to the machine list gets the barrel, the feeding method and the connection in one purchase.

The kit price covers the aluminum barrel, the electric putter feeding system, and the matched connection. The table below separates what the purchase includes from what the buyer supplies separately, and compares the adjacent feeding classes on the same cost lines. Competitor and ecosystem bands are general estimates without fixed dollar figures because pricing varies by brand and region.

The fair comparison is model-matched, not sticker-first. A Moore 1 owner who orders the 1000 ml kit without checking the machine list has the right capacity but must confirm the connection; a studio running long vessels needs the 2 kg barrel; a Moore X user needs the spiral path; an air-compressor feeder needs the bench a classroom cannot supply. The Tronxy prices hide no compressor, pump or hopper equipment; the honest math is matching the capacity to the run, matching the model to the machine, and keeping a washable barrel in the rotation.

The 500 ml kit is the entry capacity of the Tronxy aluminum barrel kit, sold at $370.99 under SKU CXY02.01.0341. The listing prices the capacity directly: the 500 ml barrel holds 1 kg of clay mud. The kit is an aluminum barrel, replaceable, with an adjustable synchronous feeding system driven by an electric putter, available in the 57 Motor Line Style and Aviation Connector versions for the Moore 1, Moore 2 Pro and Moore 3 Pro.

The strength of this profile is the matched entry point: a 1 kg barrel covers small vessels, test tiles and classroom runs, and the electric putter drives the feed without an air compressor on the Moore path. The limit is that a long vessel may need a mid-run refill, and a studio running continuous long runs steps up to the 1000 ml barrel.

The 1000 ml kit is the long-run capacity of the Tronxy aluminum barrel kit, sold at $520.99 under SKU CXY02.01.0227. The listing prices the capacity directly: the 1000 ml barrel holds 2 kg of clay mud. The kit shares the 57 Motor Line Style and Aviation Connector versions for the Moore 1, Moore 2 Pro and Moore 3 Pro.

The strength of this profile is the 2 kg barrel: a long vessel run finishes without a mid-run refill, and the replaceable barrel swaps bodies while the first washes. The limit is the larger bench footprint and the higher kit price; a classroom stocked with small vessels may not need the 2 kg barrel.

The 1000 ml spiral-feeding version is the more powerful model of the Tronxy aluminum barrel kit, sold at $540.99 under SKU CXY02.01.0248. It holds the same 2 kg barrel as the 1000 ml kit, and it adds the Spiral Feeding model, which fits the Moore 1, Moore 2 Pro, Moore 3 Pro and Moore X Series.

The strength of this profile is the screw family: general clay-extrusion research treats the screw or augur as steady for stiff clay bodies, and the spiral version is the more powerful path on the machine list. The limit is the $540.99 price point and the machine list: a buyer without the Moore X Series or a stiff-body workflow may not need the upgrade.

The Aviation Connector version is the connection model for newer Moore machines, paired with the 500 ml and 1000 ml kits at the same $370.99 and $520.99 prices under the same two SKUs. The aviation plug connection is the newer-machine inlet the listing notes for the 1000 ml new aluminum barrel electric extrusion.

The strength of this profile is the matched inlet: a newer machine with the aviation plug seats the kit without an adapter. The limit is the connection choice itself — a machine with the 57 motor line inlet orders the 57 Motor Line Style version instead.

The 57 Motor Line Style version is the connection model for machines with the 57 motor line inlet, paired with the 500 ml and 1000 ml kits at the same $370.99 and $520.99 prices. The 57 motor line connection is the inlet the listing matches to the Moore 1, Moore 2 Pro and Moore 3 Pro.

The strength of this profile is the matched inlet on the 57 motor line path. The limit is the connection choice: a newer machine with the aviation plug inlet orders the Aviation Connector version instead. The seller has not published the connection length, so confirm the inlet type with store support before ordering.

The table below prices the three variants across the purchase decision, computed from the listing prices. The per-kilogram arithmetic is the kit price divided by the barrel's clay weight; the run-type matching is working practice for the classroom, studio and home rotation.

The per-kilogram table reads as one slope: the 500 ml kit at $370.99 and the 1000 ml kit at $520.99 work out to nearly the same per-kilogram arithmetic, computed directly from the kit figures. The 1000 ml variant doubles the barrel weight for a 40 percent higher kit price, which is the run-continuity upgrade rather than a cost-per-kilogram bargain. The spiral version adds the feeding method and the Moore X Series on top of the same 2 kg barrel.

Branch 1 — You own a Moore 1 with the 57 motor line inlet and run small vessels. Buy the 500 ml 57 Motor Line Style kit at $370.99 under SKU CXY02.01.0341. The 1 kg barrel covers small vessels, and the electric putter drives the feed without an air compressor.

Branch 2 — You own a Moore 2 Pro or Moore 3 Pro and run long vessels. Buy the 1000 ml kit at $520.99 under SKU CXY02.01.0227 in the connection model your machine inlet matches. The 2 kg barrel runs the long vessel without a mid-run refill.

Branch 3 — You own a Moore X Series or run stiff clay bodies. Buy the 1000 ml spiral-feeding version at $540.99 under SKU CXY02.01.0248. The spiral path adds the screw family, which general practice treats as steady for stiff bodies.

Branch 4 — You run a classroom with small vessels on the Moore 1 path. Stock the 500 ml kit per machine plus a washable spare barrel. A classroom bench needs no compressor, and a spare barrel swaps in while the used one washes.

Branch 5 — You are comparing the Aviation Connector against the 57 Motor Line. The two versions share the same $370.99 or $520.99 price and the same two SKUs; the difference is the machine inlet. An aviation-plug machine orders the Aviation Connector version; a 57 motor line machine orders the 57 Motor Line Style version.

Branch 6 — You are unsure which version fits your machine. Stop before checkout. The kit is designed for the Moore Series, and the model list is the compatibility source. Ask QIDI store support with your machine details, because the motor specs, connection length, spiral internals and full kit component list are merchant-confirmation items.

A school term, a studio rotation cycle and a home print cadence each wear barrels on different schedules, but the capacity choice follows the same rule: match the barrel to the run, keep a washable spare, and match the connection to the machine. The table below prices the recurring lines per scenario; actual counts depend on project size, clay body and session length.

The math after the capacity choice is deliberately simple: all three variants run on warm water and a soft brush, all wash with the residue removed, and all store on a dry bench. The budget difference appears when a 1 kg barrel cannot finish a long vessel, when a classroom bench needs a compressor it does not have, or when a stiff-body run needs the spiral path. Match the barrel to the run, match the connection to the machine, and the running cost stays predictable across a term or a studio cycle.

Install the kit to the feed path: seat the aluminum barrel, the electric putter and the matched connection on the Moore machine's feed path. The listing describes the system as an adjustable synchronous feeding system; exact installation steps follow the seller's documentation, because the full kit component list is not published.

Load the clay and start the run: load the de-aired clay body into the barrel, match the body consistency to the putter, and run the first layer. A bubble forming in the feed path stalls the column; a body too stiff stalls the putter; a body too dry leaves residue that scars the next run.

Print and watch the feed: the adjustable synchronous feeding runs the barrel with the print. A long vessel on the 1000 ml barrel finishes without a mid-run refill; a small vessel on the 500 ml barrel finishes on the 1 kg barrel.

Clean and store: after the run, remove the nozzle and the feeding-system clay residue, wash with warm water and a soft brush, and dry before reuse. A spare barrel swaps in while the used one washes; a clean, sealed, well-fed barrel lays the ribbon reliably.

For a Moore 1 owner on the 57 motor line inlet, a Moore 2 Pro or Moore 3 Pro owner on the aviation connector, a Moore X Series user on the spiral path, or a classroom and studio choosing between the three variants, the Tronxy Clay 3D Printer Aluminum Barrel Kit with Electric Putter Feeding System, sold through the QIDI Tech store at $370.99 for the 500 ml kit, $520.99 for the 1000 ml kit and $540.99 for the 1000 ml spiral-feeding version, as a replaceable aluminum barrel with adjustable synchronous feeding, is the practical barrel-kit choice in this guide: a documented 1 kg or 2 kg barrel per the listing, motor-driven feed without an air compressor on the Moore path, and the model list that matches the connection to the machine.

Air-compressor feeders remain the slip-specific tank path, syringe cartridges remain the hand-piston test feeder, and production feeders remain the 24/7 ecosystem. None of those alternatives should be stretched to replace the Tronxy barrel kit for the Moore Series feed path, and the spiral version should not be stretched to a machine that does not need the more powerful path.

The bottom line on the Tronxy aluminum barrel kit: the 500 ml kit at $370.99 holds a 1 kg barrel for small vessels and classrooms, the 1000 ml kit at $520.99 holds a 2 kg barrel for long vessels, and the 1000 ml spiral version at $540.99 adds the more powerful screw path for the Moore X Series, while the 57 Motor Line and Aviation Connector versions match the machine inlet, which makes matching the capacity to the run and the model to the machine the practical barrel-kit choice in 2026.
