Windsor 3D printer filament selection guide
Pick the right filament
New to 3D printing or just dialing in a new project? Here’s a plain-English guide to the filaments we carry — what each is best at, and the temperatures to start with. Some specialty materials are stocked seasonally or available by request. Not sure what to pick? Bring your project by the Windsor shop — we’re happy to help you choose.
PLA+ (Everyday workhorse)
Best used for: Display models, prototypes, toys, signage, decor, and anything that lives indoors. The easiest material to print.
- Easiest to print — great for beginners
- Minimal warping, no enclosure needed
- Sharp detail and bright colors
- Low odor, biodegradable base
- Softens in hot cars / direct sun
- More brittle than PETG or TPU
- Not ideal for outdoor or load-bearing parts
Silk PLA (Show-stopper finish)
Best used for: Decorative prints, gifts, vases, and craft-show pieces where a glossy, metallic sheen makes the model pop.
- Lustrous, metallic-looking surface
- Prints almost as easily as PLA
- Hides layer lines beautifully
- Slightly weaker than standard PLA+
- Best printed a touch hotter & slower
- Shows stringing if under-tuned
PETG (Tough & weather-ready)
Best used for: Functional parts, brackets, outdoor items, water-resistant pieces, and anything that needs more durability than PLA.
- Strong, slightly flexible — resists cracking
- Good heat & UV resistance for outdoors
- Food-contact friendly grades available
- More stringing than PLA — needs tuning
- Sticks hard to the bed (use a release)
- Slower print speeds recommended
TPU Flex (Bend, don’t break)
Best used for: Phone cases, gaskets, straps, grips, wearables — anything that needs to flex, stretch, or absorb shock.
- Rubber-like flexibility & impact resistance
- Excellent grip and durability
- Won’t shatter like rigid plastics
- Trickiest to print — print slow
- Needs a direct-drive extruder for best results
- Not suited for rigid structural parts
ABS (Heat-tough & durable)
Best used for: Automotive parts, enclosures, tool handles, and functional pieces that see heat or mechanical stress. Can be acetone vapor-smoothed for a glossy finish.
- High heat resistance — survives hot cars
- Strong and impact-resistant
- Smooths and glues easily (acetone)
- Warps easily — enclosure & heated bed needed
- Fumes require good ventilation
- Harder to print than PLA or PETG
ASA (Outdoor-proof)
Best used for: Outdoor signage, planters, automotive trim, and anything left in sun or weather. Like ABS, but built to hold up to UV.
- Excellent UV & weather resistance
- Strong and heat-tolerant like ABS
- Holds its color outdoors
- Warps — enclosure recommended
- Fumes require good ventilation
- A bit pricier than ABS
Carbon-Fiber Reinforced (Stiff & pro-grade)
Best used for: Rigid functional parts, jigs & fixtures, drone frames, and brackets that need stiffness with low weight. Available on PLA or PETG bases.
- Very stiff and dimensionally stable
- Premium matte finish
- Lightweight strength
- Highly abrasive — hardened steel nozzle required
- More brittle than its base material
- Best with a 0.5mm+ nozzle
Glow-in-the-Dark PLA (Lights-out fun)
Best used for: Night signage, toys, Halloween & cosplay pieces, and novelty decor that glows after soaking up light.
- Charges under light, then glows in the dark
- Prints much like standard PLA
- Fun for gifts and craft-show pieces
- Abrasive — hardened nozzle recommended
- Slightly weaker than plain PLA
- Glow fades over time and needs recharging
Wood-Fill PLA (Real wood look)
Best used for: Rustic decor, picture frames, signage, and gifts that should look and feel like real wood.
- Looks & smells like wood
- Can be sanded and stained
- Warm, matte natural finish
- Abrasive — hardened nozzle recommended
- Can clog — use a 0.5mm+ nozzle
- More brittle than plain PLA
