    • Simplify3D: Simplify3D offers a comprehensive “Print Information” panel that includes estimated filament weight.

    Tips for minimising filament waste and reducing print costs

    • Optimise print settings: Reduce infill density, wall thickness, and support structures to minimise filament usage.
    • Use infill patterns: Choose infill patterns that provide structural integrity while minimising filament usage.
    • Design efficient models: Design models that require minimal support structures and optimise for printability.
    • Calibrate your printer: Properly calibrated printers produce fewer errors and reduce filament waste.
    • Recycle failed prints: Failed prints can be recycled into new filament, reducing waste and saving money.

    Beyond filament cost: considering other expenses

    While filament cost is a significant factor, it’s essential to consider other expenses associated with 3D printing.

    • Electricity costs: 3D printers consume electricity, which can add up over time.
    • Maintenance costs: Regular maintenance and replacement of parts are necessary to keep your printer running smoothly.
    • Post-processing costs: Post-processing techniques, such as sanding, painting, and finishing, can add to the overall cost.

  • Silk 3D Printer Filaments: Are Expensive Filaments Better Than More Affordable Alternatives?

    3D printing enthusiasts are always on the lookout for materials that enhance both the visual appeal and functionality of their prints. Among the many filament options available, silk PLA has gained significant popularity for its glossy, metallic-like finish that makes prints look premium straight off the printer. But when it comes to purchasing silk filaments, many users face a dilemma: Is it worth paying for more expensive silk filament brands, or will budget options suffice?

    What is silk PLA filament?

    Silk PLA is a modified version of standard PLA (polylactic acid) filament, infused with additives that enhance its sheen, smoothness, and overall finish. These filaments are known for their ability to create visually striking prints with a reflective surface, making them ideal for decorative objects, figurines, vases, and artistic models.

    Compared to standard PLA, silk filaments often have slightly reduced strength and may require adjustments in printing settings such as slower speeds and lower temperatures to achieve optimal results. However, their aesthetic appeal makes them a favourite for projects where appearance matters most.

    Expensive vs. budget silk filaments: what’s the difference?

    With a wide range of silk PLA options available, prices can vary significantly. While some brands charge a premium for their filaments, others offer more budget-friendly alternatives. Here are some key differences to consider when deciding whether to invest in a pricier silk filament:

    Print quality & consistency

    Premium brands like Polymaker, Prusament, and eSun often provide better colour consistency, reduced stringing, and improved layer adhesion. Lower-end brands might suffer from uneven extrusion, which can cause inconsistencies in the final print’s appearance.

    Material composition & strength

    Cheaper silk filaments might have higher concentrations of modifiers, which can weaken prints, making them more brittle. More expensive filaments often achieve a balance between glossiness and durability, ensuring prints are not just beautiful but also functional.

    Diameter tolerance & printing reliability

    High-end silk filaments maintain tighter diameter tolerances (e.g., ±0.02mm), reducing the chances of clogging and ensuring smoother extrusion. Budget filaments may have less precise tolerances, leading to inconsistent feeding and potential nozzle blockages.

    Colour & visual effects

    While both expensive and budget silk filaments offer vibrant colours, premium brands tend to provide richer hues, unique blends, and multi-tone options. Some advanced silk filaments also offer dual-colour or rainbow effects that change appearance based on the viewing angle. Additionally, multi-colour silk filaments are available, providing stunning gradient effects that enhance the visual appeal of prints.

    Is it worth paying more?

    If you’re printing decorative models where appearance is the top priority, investing in a higher-quality silk filament can save time and frustration, reducing post-processing and ensuring better results. However, if you’re printing simple objects and don’t mind occasional inconsistencies, a budget silk filament can still provide excellent results with proper settings.

    Ultimately, the choice depends on your needs, printer capabilities, and budget. If reliability, smooth extrusion, and vibrant colour depth matter to you, premium silk PLA is worth the extra cost. If you’re experimenting or printing non-critical designs, budget options can still deliver great-looking prints with some fine-tuning.

    Choosing the right filament for your project

    Selecting the right filament depends on your project’s requirements, budget, and printer capabilities. Ask yourself:

    • Is strength a priority? Nylon or carbon fiber may be the best choice.
    • Need something beginner-friendly? Start with PLA.
    • Printing functional parts? ABS or PETG offers durability.

    Caring for your filaments

    No matter which filament you choose, proper storage is key. Most filaments are hygroscopic, meaning they absorb moisture from the air, leading to poor print quality. To maintain filament quality, store them in airtight containers with silica gel packets. For long-term storage, use filament dryers.

  • Battle in the Bargain Bin: Which Cheap 3D Printing Filament is Best?

    Selecting the right filament is crucial for achieving quality prints. However for amateur ethusiasts and professionals alike, money talks. Here we compare five low-cost filaments available in 1kg spools, focussing on both price and performance.

    Polylactic Acid (PLA) filaments dominate the 3d printing bargain bin as they are relatively cheaper to manufacture than other filament types. PLA is derived from renewable resources such as corn starch or sugarcane, making it more sustainable and cost-effective to produce. In contrast, filaments made from other materials are petroleum-based, which makes their production costs more sensitive to fluctuations in oil prices.

    Some of the cheapest filaments available are listed below.

    One user commented:

    “I see a lot of comments out on the net with advice to steer clear of stuff like this. It’s cheap and of course has to be rubbish because of that.

    Being the adventurous sort on a tight budget I ignored common advice and bought some. That was three years ago. Since then I have purchased several more rolls and a a few of these multipacks (when they are available).

    To be fair to Amazon they don’t make any claims to this being premium PLA. Are there better ones? Absolutely there are. For many you pay quite a bit more as well. On a budget, this PLA is just fine. I get perfectly satisfactory prints with high detail and reliable replication across different prints… So far, I have found this PLA to be one of the most consistent and reliable at this price range.”
