Virtual Technician & Usage Guide
⚠️ Safety & Handling Warnings:

• Moisture Absorption: PLA+ is hygroscopic. Always store it in a vacuum-sealed bag with desiccant when not in use to prevent brittle filament and stringing.
• Temperature Tolerance: Do not exceed 230°C in your hotend, as PLA+ can degrade and clog the nozzle at excessively high temperatures.
• Bed Adhesion: While a heated bed is not strictly mandatory, a cold bed can lead to warped corners on larger mechanical prints.
• Print Settings — Numakers PLA+ to Standard FDM Printer (e.g., Ender 3):

Setting Recommended Value Notes

• Hotend Temperature :  190°C - 220°C 205°C is a solid starting point for a 0.4mm brass nozzle.
• Bed Temperature: 50°C - 70°C 60°C on a glass or PEI bed yields excellent first-layer adhesion.
• Cooling Fan :100%Turn on after the first layer for crisp overhangs and bridging
• Retraction Distance: 3mm - 6mm
  Bowden setups (5-6mm); Direct Drive setups (1-3mm)

Accessories Included in the Box:

• 1× Numakers Green PLA+ 1.75mm Filament (1kg Net Weight), Vacuum-sealed bag with desiccant pouch

Frequently Asked Questions (FAQ) ?

• Is the Numakers PLA+ compatible with my Creality Ender 3?
  Yes, it works perfectly with the Ender 3 and any standard FDM printer that accepts 1.75mm filament.
• Can I use this filament with a Prusa i3 MK3S+?
  Absolutely, the ±0.03mm dimensional accuracy ensures reliable and consistent feeding through the Prusa Extruder.
• Do I need an all-metal hotend to print this PLA+?
  No, a standard PTFE-lined hotend is completely sufficient since the recommended printing temperature stays below 230°C.
• Is this filament compatible with 3D pens?
  Yes, as long as your 3D pen accepts 1.75mm PLA material and can reach temperatures between 190°C and 220°C.
• What is the best printing temperature for this Green PLA+?
  We recommend starting at 205°C and adjusting between 190°C and 220°C based on your specific printer and print speed.
• Does this filament require a heated bed?
   While you can technically print on a cold bed with painters tape, a heated bed set to 60°C yields the best first-layer adhesion.
• Do I need a cooling fan for this material?
  Yes, 100% part cooling fan speed is highly recommended after the first layer to achieve crisp overhangs and bridging.
• How do I properly load this filament into my extruder?
  Heat the nozzle to 200°C, cut the filament tip at a sharp 45-degree angle, and gently push it through the extruder gear.
• Does the spool fit standard printer spool holders?
  Yes, the 1kg spool dimensions are industry standard and designed to fit on almost all stock FDM printer spool holders.
• Do I need to clean the print bed before printing?
  Yes, wipe the bed with isopropyl alcohol (IPA) before a print to remove finger oils for optimal first-layer adhesion.
• What retraction distance should I use for PLA+?
  For Bowden tube setups use 5-6mm, and for Direct Drive setups use 1-3mm to prevent stringing and oozing.
• Which slicer profile should I select to get started?
  You can start with a generic "PLA" or "PLA+" profile in Cura or PrusaSlicer and lightly tweak the extrusion temperatures.
• What is the recommended print speed for structural parts?
  A speed of 30-90 mm/s works best, with outer walls printed slower (around 30-40 mm/s) for a better surface finish.
