Light Weight PLA Filament 1.75mm Bright Orange - Low Density Print

In this review the focus is on practical use: Polymaker Light Weight PLA 1.75mm in bright orange is for makers who want lower-weight, rigid prints using standard PLA settings. The single biggest reason to buy is that it cuts filament mass without changing nozzle or bed temperatures, so users can try lighter parts without a steep learning curve. The reviewer found it especially useful where stiffness and low weight matter, while noting a few handling and strength nuances reported by other users.

Key Features

• Low density: The filament runs at about 0.9g/cm3, allowing lighter final parts compared to regular PLA for weight-conscious builds.
• PLA compatibility: It prints with the same nozzle and bed temperatures as standard PLA, simplifying setup and avoiding a separate profile for many printers.
• No foaming during print: Unlike some lightweight PLA options, this material does not foam while extruding, which reduces common print defects.
• High rigidity and layer adhesion: Prints come out stiff with reliable layer bonding, which is useful for structural or radio-controlled model parts.
• Matte finish and color consistency: The bright orange spool delivers a matte surface that conceals layer lines and accepts paint well.
• Packaging and handling: The spool is dried, vacuum-sealed with desiccant and wound to minimize tangles for easier use.

Who It's For

The filament suits hobbyists and makers who need lighter-than-normal PLA parts but want to keep standard print settings; examples include RC modelers making stiff, low-mass control surfaces and prototype builders trimming overall assembly weight. Its matte finish also makes it appealing to those who will paint or finish parts after printing.

Those seeking extreme flexibility, maximum toughness, or an ultra-lightweight open-cell foam effect should look elsewhere, because this product trades some impact resilience for rigidity and does not foam during printing. Users who need extremely consistent ultra-light density across many batches should test a sample before committing to large prints.

Pros & Cons

Pros

• Lower density reduces part weight without changing print temperatures.
• Good rigidity and layer adhesion produce stiff, usable parts for functional applications.
• Matte surface and consistent color conceal layers and take paint well.
• Well packaged to reduce moisture and tangles out of the bag.

Cons

• Some users report variability in perceived weight and occasional brittleness on delicate prints.
• Stringing was noted by a minority of users, so tuning retraction may be necessary.

Specifications

Our Verdict

Polymaker Light Weight PLA in bright orange is a solid choice for makers who want lighter, rigid parts without changing printer settings, offering good bed adhesion and a paint-ready matte finish. It's good value for functional models and RC parts, though those needing maximal toughness or ultra-consistent ultra-light density should validate with small tests first.

Frequently Asked Questions

Does this filament require special slicer settings?
No, it uses the same nozzle and bed temperatures as regular PLA, so most printers can use existing PLA profiles with minor tuning.

Will it foam during printing?
No, this lightweight PLA is formulated to avoid foaming and the related print defects.

How should I store the filament?
Keep it in the resealable vacuum bag with the desiccant and avoid nodes by holding the filament tip when unspooling.
