🧵 About Our 3D Printing Filament – RS3D

Welcome to RS3D’s comprehensive guide to 3D printing filament. We believe in not only offering high-quality materials but also helping our customers make informed, eco-conscious decisions about the filaments they use.

Whether you're crafting toys, prototypes, home décor, or functional parts, we use the best filament types for your needs — with options that are biodegradable, durable, flexible, and even recyclable.

🧪 What is 3D Printer Filament?

3D printer filament is a thermoplastic material, typically 1.75mm in diameter, fed through the hotend of a 3D printer where it melts and is layered to form a physical object. Each filament type has its own print characteristics, strengths, finishes, and environmental impact.

🔍 Filament Types Used by RS3D

We carefully select our filaments based on print performance, safety, customer usage, and environmental impact.

---

🌱 PLA (Polylactic Acid) – Biodegradable & Easy to Print

Source: Made from renewable resources like corn starch or sugarcane.

Eco Impact: Bioplastic – industrially compostable but not suitable for home composting.

Print Ease: Low warping, no heated bed required, little to no odor.

Strength: Moderate — brittle under high stress.

Finish: Matte to semi-gloss, available in many colors and effects (silk, rainbow, glitter).

Best Uses: Toys, display items, miniatures, cosplay, classroom models.

 

---

💪 PETG (Polyethylene Terephthalate Glycol) – Tough & Recyclable

Source: Glycol-modified version of the same plastic used in water bottles.

Eco Impact: Recyclable in many areas (#1 plastic) if clean and sorted.

Print Ease: Less brittle than PLA; resistant to UV and moisture.

Strength: High — more flexible and impact-resistant than PLA.

Finish: Smooth, slightly glossy.

Best Uses: Mechanical parts, enclosures, vases, food-safe containers.

 

---

🧼 TPU (Thermoplastic Polyurethane) – Flexible & Shock Absorbent

Source: A flexible plastic with rubber-like texture.

Eco Impact: Not easily recyclable curbside; special processing required.

Print Ease: Challenging for some printers due to flexibility.

Strength: High — elastic, durable, and wear-resistant.

Finish: Matte, rubbery texture.

Best Uses: Fidget toys, phone cases, wheels, gaskets, impact-resistant parts.

🎨 Specialty Filaments

We also use various specialty filaments for custom jobs or specific customer requests:

Silk PLA – high-gloss, smooth texture, ideal for trophies and decor

Glow-in-the-Dark PLA – phosphorescent prints for night visibility

Wood-Filled PLA – infused with real wood fibers for natural appearance and scent

Carbon-Fiber Reinforced Filaments – lightweight but extra strong

♻️ Recycling & Environmental Responsibility

♻️ Is 3D Printer Filament Recyclable?

 

Spools: Most RS3D spools are made from recyclable PET or ABS plastic.

Scrap Prints: We encourage customers to sort scraps by material and check with local recycling programs or third-party services.

Popular Filament Recycling Options:

Filabot or ReDeTec: In-home filament recycling systems

Printerior (USA): Send in waste plastic in exchange for credit

KiwiFil (NZ): Recycle old spools or prints for store credit

🌿 RS3D Sustainability Practices

We’re not just printers — we’re parents, creators, and advocates for a better planet. Here's what we do to reduce our environmental footprint:

✅ Use biodegradable PLA and recycled PETG whenever possible

✅ Offer low-waste packaging and spool return options

✅ Minimize failed prints with optimized slicer profiles

✅ Include misprints as free gifts in qualifying orders

✅ Reuse shipping boxes and packing supplies when clean

✅ Group print jobs and shipments to reduce power & carbon usage

✅ Exploring solar and filament regrind systems in-house

💡 Tips for Eco-Friendly 3D Printing at Home

Use tree supports and minimal infill

Don’t toss failed prints — use them for tests or batch recycling

Separate PLA and PETG — mixing ruins recyclability

Save empty spools for rewinding or recycling

Donate unwanted prints to teachers, hobbyists, or STEM clubs
