Problems, parts and running costs

Summary

A single roughly 3 kg spool of black eSUN PLA+ (PLA Pro) in 1.75 mm, aimed at long runs and print farms rather than three smaller rolls. Check your printer’s external spool holder and feed path first: the reel is about 270 mm across and 104 mm wide, so it does not fit an original Bambu AMS, and stock was zero on eSUN’s US store on October 29, 2026.

Strengths

  • One continuous 3 kg supply of a consistent nominal black formulation reduces spool changes for long runs or a farm.
  • Toughened PLA for indoor parts: eSUN’s published values support better directional toughness than standard brittle PLA in its own test regime.
  • Common desktop temperatures with no enclosure, water cooling or abrasive nozzle required.
  • Owners on r/3Dprinting describe eSUN PLA+ as a normal default PLA; color-specific calibration helps.
  • A documented drying response: one April 2026 poster saw markedly cleaner black PLA+ miniature details after eight hours in a dryer.
  • A specialty retailer identifies the genuine black 3 kg SKU and size, reducing risk of receiving three small rolls or PLA+HS.

Weaknesses

  • Feed filament can be brittle: owners describe PLA+ breaking between spool and printer on separate rolls while printed parts stayed sound.
  • Stringing and surface fuzz: owners report pervasive PLA+ stringing; humidity, color-specific temperature and retraction matter.
  • Large-roll drag: a 3 kg spool can add pull resistance on a holder built for 1 kg; a freely rolling external stand is needed.
  • No AMS fit: the 270 × 104 mm reel exceeds the original AMS limits and must feed externally or be respooled.
  • Color and lot variation: owners report black and orange PLA+ behaving differently under comparable settings; slight lot differences are cautioned.
  • No trustworthy defect statistics for this exact 3 kg black spool: no measured undersize/oversize, knots, seal failures or scrap rate was found.

Verified specifications

Identityblack eSUN PLA+ 1.75 mm, 3000 g net filament, manufacturer number PLA+175B3B1, retailer ESUNCN-PLA+175B3B1, EAN 6922572240018. Not three 1 kg rolls and not PLA+HS, PLA-Basic, PLA-Matte or PETG.
Chemistrymodified PLA (PLA+/PLA Pro), opaque black, for FDM/FFF printers accepting 1.75 mm. Not an abrasion-filled material; hardened nozzle not specified.
Diameternominal 1.75 mm ±0.03 mm per eSUN’s PLA+ family listing; no independent full-spool micrometer series for this exact 3 kg black lot.
Spoolabout 270 mm outer diameter, 104 mm width; hub bore quoted 50, 52.5 or 55 mm by different retailers. Measure the actual roll before printing an adapter.
Feeder fitoriginal Bambu AMS accepts 197-202 mm diameter and 50-68 mm width, so this 270 × 104 mm spool must feed from an external holder or be respooled.
Printing210-230°C nozzle, 45-60°C heated bed, 100% part-cooling fan; published high-speed parameter under 300 mm/s, not a guarantee.
DryingeSUN recommends 50°C for 8-12 hours when needed; confirm the dryer physically fits a 270 mm reel.
Material (eSUN test samples)density 1.24 g/cm³, melt flow 3.7 g/10 min at 190°C/2.16 kg, heat deflection 53.78°C. Tensile XY 70.37 MPa, Z 36.36 MPa; flexural XY 100.3 MPa, Z 56.4 MPa.
Lengthabout 1006 m (3300 ft) from 3000 g, 1.24 g/cm³ and a round 1.75 mm filament — a geometry estimate, not a measured length.
Safetymanufacturer promotes food-contact/EN71/FDA-related raw-material compliance; does not establish that an arbitrary finished FDM part in black is safe for reusable food contact. PLA needs industrial composting.

Day-to-day annoyances

  • Finding or printing a holder rated for a 270 mm, 104 mm-wide, 3 kg reel, and clearing gantry, enclosure, dryer and runout sensor.
  • Cannot load into an original Bambu AMS as shipped; material prints from an external feed.
  • One open package for the whole supply; three individually sealed 1 kg rolls may preserve unused material longer.
  • Drying a 3 kg drum is a hardware problem: many 1 kg dryers are too small, and center-to-surface uniformity was not tested.
  • PLA+ still has PLA thermal limits: about 54°C heat deflection risks deformation in hot cars or direct sun; black pigment raises solar heating.
  • Food-contact and compostability claims require caution for FDM parts.

A price shown on an out-of-stock color is not a buyable offer.

  • eSUN US official store, exact 3 kg spool: $42.99 advertised ($68.97 comparison), black selectable but 0 in stock; $14.33/kg reference only. Shipping terms show $5.99 US shipping and free over $99, so a hypothetical $42.99 order would be $48.98, but it is not order-ready.
  • eBay listing, eSUN-named store, item 407110040197: $61.98 with free shipping, 10 available, new from Los Angeles; $20.66/kg. Title says “High Speed Big Bundle,” so confirm it is regular PLA+ on one 3 kg spool, not PLA+HS.
  • eBay second selector, item 407115995232: $62.39 with volume discounts, but black explicitly out of stock.
  • 3DJake International exact black 3 kg: $46.38 ($15.46/kg) for PLA+175B3B1, EAN 6922572240018, in stock, before delivery and import fees; not verified as a final US landed price.
  • Three separate 1 kg eSUN PLA+ rolls: nominal $15.99 each, $47.97 for 3 kg at promotional pricing, also showing zero US stock when checked.
  • Editorial targets: $38-42 new for 3 kg is outstanding with working delivery and a suitable external holder; $43-49 delivered is solid; $50-55 delivered is reasonable only if avoiding roll swaps matters; above $60 the 3 kg roll is hard to justify on cost alone.

Parts and consumables

  • Primary consumable: 1.75 mm black eSUN PLA+, nominal 3000 g, PLA+175B3B1, EAN 6922572240018. Replenishment is by spool, not a schedule; observed $42.99 advertised unavailable or $61.98 available, about $0.0143-$0.0207 per gram before shipping and tax.
  • Vacuum storage bag or desiccant: unopened PLA+ ships vacuum-sealed; store cool and dry. No verified kit that fits 270 × 104 mm was found. Replace when damaged or saturated.
  • Printer nozzle, build plate and feed fittings: standard wear parts; this non-abrasive PLA+ needs no proprietary nozzle. No eSUN-specific wear interval.
  • The 3 kg spool is not a refill: eSUN sells separate spoolless refill and 1 kg reusable-spool adapters.

Running costs

  • At nominal 3000 g, raw material costs $14.33/kg on the unavailable direct $42.99 display or $20.66/kg on the available $61.98 listing, before shipping and tax. Actual useful part cost is higher once failed prints, purge, brims, supports and leftover length count.
  • A print consuming 150 g uses about $2.15 of material at the unavailable direct display value or $3.10 at the $61.98 listing; at the nominal $15.99/kg on separate 1 kg rolls it would be $2.40. Material only, not full printed-part cost.
  • No spool-specific electricity or subscription. Printer electricity, wear, labor, drybox or dryer electricity and failed-print material are separate expenses.
  • Drying energy depends on dryer power and cycle: 50°C for 8-12 hours is the maker’s guidance, but no measured wattage with this specific reel was checked.
  • Waste and end-of-roll: geometry gives about 1 km, but actual usable material can be less. No defensible general scrap rate was available.

Support and warranty

  • eSUN US store: request within 14 days of delivery; unused goods in original packaging with receipt or proof. Change-of-mind returns are at customer shipping cost; wrong or damaged goods caused by the seller can qualify for a seller-paid remedy. No restocking fee stated.
  • Support channel: after-service@esun3d.com and estore@esun3d.com. No clearly documented fixed-duration PLA+ 3 kg manufacturing-defect warranty was found.
  • Marketplace policies differ: Newegg’s eSUN Official Store mentions 30-day refund or replacement pathways, and the read eBay seller lists 30-day returns on one available black 3 kg offer. Do not transfer those rights to the manufacturer’s web shop or 3DJake.
  • Inspect packaging, label, spool diameter and flange before opening; after opening, run a small temperature tower and photograph repeated measured diameter violations or tangles, and contact the seller promptly with order or lot number.

Alternatives

  1. eSUN PLA+ black, three separate 1 kg rolls: nominal $15.99 each, $47.97 for 3 kg on eSUN’s US promotional store, also showing zero US stock when checked. Same general PLA+ family on smaller individually sealed rolls; better for typical 1 kg holders, AMS workflows or infrequent black printing.
  2. eSUN PLA-Basic black, three 1 kg rolls: $12.99/kg, $38.97 for three before shipping. Lower-cost regular PLA when easy printing and appearance matter more than PLA+’s tougher-formulation claims; different formulation, so requalify temperatures and strength.
  3. eSUN PETG black, three 1 kg rolls: $14.99/kg, $44.97 for three before shipping. Better when heat resistance, tougher ductility or occasional outdoor exposure matter; PETG needs its own bed temperature, cooling and drying profile.

Which model this is

This page covers the single 3 kg black spool of eSUN PLA+ (PLA Pro), 1.75 mm, manufacturer number PLA+175B3B1, EAN 6922572240018. It is not the PLA+HS, PLA-Basic, PLA-Matte, PETG or spoolless refill products, and not three 1 kg rolls.
