PolySmooth PVB Filament 1.75mm 0.75kg Orange - Smooths with IPA

Our review of the PolySmooth PVB filament finds it best suited for makers who want PLA-like printing with an easy smoothing path using isopropyl alcohol. Printed under typical PLA conditions, this orange PVB gives reliable dimensional accuracy and bed adhesion, and the single biggest reason to buy is its ability to be quickly transformed from a matte, layered print into a glossy, smooth part by spraying 99% IPA or using a Polysher. It is a practical choice for hobbyists and professionals who prioritize post-process finish over extreme engineering properties.

Key Features

• Easy to smooth: The outer layer dissolves with 99% IPA so prints become glossy and show minimal layer lines after light spraying or Polysher finishing.
• PLA-like printing: Prints under similar temperature and bed settings as PLA, making it simple to switch materials without extensive tuning.
• Tangle-free packaging: Filament is wound carefully, dried, and vacuum sealed with desiccant to reduce moisture before first use.
• Consistent print performance: Users report good bed adhesion, minimal warping, and reliable extrusion when the filament is dry and handled correctly.
• Dimensional accuracy: The material prints with consistent color and predictable dimensions for parts that need post-process smoothing.

Who It's For

PolySmooth is ideal for hobbyists, small workshops, and designers who want smooth, display-ready prints without sanding or complex chemical baths. If you plan to produce finished models, props, or visual prototypes and you have access to 99% IPA or a Polysher, this filament offers a straightforward workflow from printer to glossy object.

Those who need high-temperature resistance, structural engineering grades, or a moisture-tolerant material should look elsewhere; PolySmooth is more moisture sensitive than standard PLA and benefits from storage in a dry box to avoid print problems. Occasional users who cannot control filament humidity may see inconsistent results.

Pros & Cons

Pros

• Prints like PLA under similar settings for easy adoption on most printers.
• Smoothing with 99% IPA produces a glossy finish and reduces visible layer lines quickly.
• Vacuum sealed and dried packaging lowers initial moisture and tangling risk out of the box.
• Reliable bed adhesion and low warping when used correctly.

Cons

• More prone to moisture absorption than regular PLA, so a dry box is recommended to avoid printing issues.
• Some users report mixed filament quality and occasional breakage in the extruder when filament is not perfectly dry.

Our Verdict

PolySmooth PVB 1.75mm is a practical choice for creators who want a hassle-free path from printed part to polished finish; it prints like PLA and delivers impressive glossy results after IPA smoothing. Buyers who keep filament dry and accept that this is a finish-oriented material will find it good value for display parts and prototypes, while those needing moisture-robust or engineering plastics should consider alternatives.

Frequently Asked Questions

Can I smooth PolySmooth with ordinary rubbing alcohol?
Use 99% IPA for best results; lower concentrations will work less effectively and may require longer application or multiple passes.

Does PolySmooth need special storage?
Yes, it is recommended to keep the spool in a dry box or sealed with desiccant because it absorbs moisture more readily than standard PLA.

What printer settings should I start with?
Begin with a nozzle temperature around 200 C, bed at 50 C, and print speed near 60mm/s, then fine tune for your machine.
