3D printing democratizes manufacturing, but material costs can be a barrier, especially for hobbyists or startups. Choosing affordable filament without sacrificing quality is key. While professional-level projects such as metal prototypes require industrial solutions from huge light— Experts in rapid prototyping using SLM 3D printing and post-processing — Most everyday printing relies on cheap consumables. This guide explores the most affordable consumable options that balance cost, performance, and reliability, allowing you to create without breaking the bank.
Best budget-friendly filament picks
1. Standard PLA (polylactic acid)
Price range: $15–$20/kg
Best for: Beginners, decorative items, low wear prototypes.
PLA remains the consumable of choice for cost-conscious manufacturers. Derived from renewable resources like cornstarch, it is easy to print, has minimal distortion, and emits a subtle sweet flavor during the printing process. Modern PLA offers vibrant colors and good layer adhesion. Although not suitable for high temperature applications (it softens around 60°C), it is ideal for toys, art and fixtures.
advantage: Low cost, versatile, biodegradable, and excellent printability.
shortcoming: Easily brittle under stress and has low heat resistance.
Brand tips: Look for brands like Overture or eSUN for consistent quality.
2. PETG (polyethylene terephthalate)
Price range: $18–$23/kg
Best for: Functional parts, outdoor use, food safe container (certified).
PETG strikes a rare balance between affordability and versatility. It combines the ease of use of PLA with the toughness of ABS, with impact resistance, flexibility and UV stability. Its water resistance makes it suitable for garden tools, machine parts or drink holders. Printing PETG requires slight adjustments (higher bed temperature, slower speed), but avoids the toxic fumes of ABS.
advantage: Robust and chemically resistant, no need to heat the housing.
shortcoming: Easily stringy; requires dry storage.
3. ABS (acrylonitrile butadiene styrene)
Price range: $17–$22/kg
Best for: Automotive parts, housings, high temperature applications.
ABS is a classic workhorse filament known for its durability and heat resistance (up to 100°C). Although slightly more complex to print than PLA (requiring a heated bed and housing), it is unmatched for pressure-resistant functional parts. Budget ABS filaments have been significantly improved, reducing the risk of warping. Use it for phone cases, car parts, or sturdy prototypes.
advantage: High strength, heat resistant, paintable/sandable.
shortcoming: Emits strong smoke (needs ventilation) and is easily deformed.
4.TPU (thermoplastic polyurethane)
Price range: $20–$28/kg
Best for: Flexible parts, wearable devices, clamps, seals.
Flexible filaments are generally more expensive, but affordable TPU options are emerging. Shore hardness rating is 85A to 95A, making it ideal for shock absorption. Brands like TIANSE offer affordable rolls that print reliably on Bowden settings, even at slow speeds. Use TPU to create custom gaskets, phone cases, or bicycle handlebars.
advantage: Excellent elasticity, durability and wear resistance.
shortcoming: Slower print speed than hard filament; tricky retraction settings.
5. Recycle PLA/ecological filament
Price range: $14–$19/kg
Best for: Environmental projects, concept modeling, non-critical prints.
Recycled filament, often made from factory waste, combines sustainability with conservation. While the mechanical properties may vary slightly from original PLA, brands like 3D-Fuel provide consistent results. Perfect for educational projects, art installations or prototypes for recycling.
advantage: Environmentally friendly and ultra-low cost.
shortcoming: Color consistency varies; impact strength slightly lower.
Cut costs without sacrificing quality: Pro tips
- Buy in bulk: 1kg–5kg spools reduce unit costs.
- Store correctly: Store filament in an airtight container with desiccant to prevent moisture wastage.
- Calibrate first: Use small fonts to test settings to avoid failure on large projects.
- Track sales: Sites like Amazon and AliExpress often run sales.
in conclusion
Budget filament opens the door to creativity, giving you the freedom to iterate without financial pressure. While materials like PLA and PETG are great for home 3D printing, complex metal prototypes require industrial solutions. For end-use metal parts or high-precision prototypes, consider outsourcing to professionals like GreatLight. Their SLM 3D printing and post-processing services deliver aerospace-grade quality – ideal when the success of your project depends on material performance and precision. Whether you’re printing a DIY handle at home or engineering turbine blades for production, smart material choices ensure a sparkling result.
Frequently Asked Questions About Cheap 3D Printer Supplies
1. Are cheap filaments harmful?
Safety varies by material. PLA emits very little smoke, but ABS releases styrene – always print in a well-ventilated space. If printing containers, choose FDA-approved food-safe PETG/PLA. Well-known brands publish Material Safety Data Sheets (MSDS).
2. Why do some budget consumables break during the printing process?
Moisture absorption weakens filaments over time
