How to Save Money When Buying Pla Film

We’ve already shown you a few tips on how to use every last meter of filament. For example, not long ago, we ran a contest on Printables.com, where you uploaded great projects using the last 5 (or less) meters of filament. We think that this topic is full of potential so we decided to compile a list of several useful tips to save material (and money) that you might be interested in. It makes sense that some of the following examples will be used in very specific ways but it’s still good to keep them in mind to save the environment and your wallet.

Herofu supply professional and honest service.

1. PrusaSlicer settings

PrusaSlicer is a powerful tool for printing both visual and technical parts. We definitely recommend learning how to use Expert mode – with it you should be able to print both great-looking and functional parts with minimum errors. Anyway, we don’t want to overwhelm you, so we’ll share the essentials of saving filament when printing visual parts. First, go to print settings, reduce the number of bottom layers and choose infill that saves material. PrusaSlicer 2.5.0. (and newer) has Lightning infill which is by far the best type of material-saving infill. If you don’t like this type, there are others that work almost as well as the lightning infill – support cubic, for example. Keep in mind that both of these infills are suitable for visual models only – technical parts need stronger internal support. And be aware that saving infill, in general, may lead to print failure. Printing some structures (or materials) may cause material build-up that gets in the way of the nozzle. If you print large and complex models, don’t decrease infill at any cost, you don’t want the print to fail in half.

The lightning infill may not look nice but it saves a lot of material

2. Try printing without supports

Print supports combined with complex models significantly decrease print speed and consume a lot of material. Many 3D models can be easily printed without supports by rotating them the right way or cutting them in two (or more parts) in PrusaSlicer. A model cut in half can be easily glued together and visible seams will disappear with postprocessing. After all, plenty of visual models are being sanded and painted anyway so masking any seams isn’t going to add much hard work to it. But if you still insist on printing the model in one piece, we suggest using the paint on supports function in PrusaSlicer. This powerful tool lets you make supports only where it’s really needed.

3. Print a detachable print supports

This cool trick we’ve already covered in one of our previous articles uses the color change (pause print) function to give you an option to insert reusable print supports. This might be useful for printing large quantities of models with overhangs over and over again. You simply print a support structure with another material and set a pause print function right before printing the overhangs. Then, you add the structure to the model. But be aware that if you print the support structure with the same material, it will adhere too much to the model and you won’t be able to remove it. We suggest combining tough filaments with flexible supports (and vice versa) with a layer of stick glue.

4. Don’t waste filament on useless stuff

Yes, you’re reading it right. Owning a 3D printer at home should come with some responsibilities. One of them is resisting the temptation to print every stupid little thing that is available online. And yet, almost everybody prints something useless from time to time. This leads us to a simple question you could perhaps ask yourself before every print – is this really something I need or want so much? Now, we don’t want to pose as a moral authority here, especially when we also like to print stuff just for plain old fun from time to time. On the other hand, there’s a clear line between “Oh, this is a bust of my favorite character, I want it!” and “I haven’t printed anything in two days. I. MUST. PRINT.SOMETHING.” It would be a shame if your 3D printer turned into an expensive garbage generator.

5. Give unused models a second life

This requires some creative thinking but try to reuse failed prints, print garbage and unused prints. Even the simplest models can be reused for another purpose. It may be even something as simple as a blob or MMU2S wipe tower melted by heat gun (see LARP gadgets article). There are so many ways and all you need is to be creative. And if you’re out of ideas, try to give or sell the models to someone else. You may not be able to reuse it but other people may have some ideas on what to do.

Blobs and melted MMU2S wipe towers may be used as sci-fi props for LARPs, various games and movies…

6. Fix failed prints

Everybody deals with failed prints from time to time, nothing and nobody is perfect. But don’t worry, some failed prints can be fixed quite easily. For example, if you print a visual model that will be painted lately and all of sudden the printer nozzle gets clogged, it’s not the end of the world. You can simply measure the height of the printed part, then slice the model in PrusaSlicer and print the rest of the model. Then you can glue it together, and use putty and sandpaper to mask the failed part. After the paint job is done, no one will notice anything.

7. Use every last meter of filament

There’s one great thing about the Original Prusa 3D printers and that is the filament sensor. If it’s plugged in and calibrated, you can use it for finishing all filament leftovers you have at home. We use it all the time, mostly for printing large models that are about to be painted.

8. Use recycled filaments for printing

Have you heard about our Prusament PLA and PETG recycled? If not, it may be about time to read our release articles (PLA and PETG) and perhaps try printing with them. Our recycled Prusaments are made from waste that is being generated during the Prusament manufacturing process. Thanks to this process we’re able to make high-quality filaments that are cheaper than regular Prusaments.

9. Fix your prints with a 3D pen

Do you have a 3D pen that works with the same materials as your 3D printer? That’s great, you can use it for fixing broken or failed prints!

10. Place a recycle mark on the print

In some situations, it might be quite useful to have a recycle mark on the print. If you eventually decide to throw away something 3D printed, someone can use that mark to identify the type of filament and re-use it. Unfortunately, 3D printed materials (even marked ones) are being sorted as non-recyclable and incinerated in the Czech recycling plants. However, there may be some projects that may be able to use 3D printed materials. And who knows what will happen in the near future? The technology might finally make a big step forward – and suddenly, the 3D printed parts will be recyclable. So we definitely recommend placing a recycle mark on your model before slicing in PrusaSlicer.

In case you don’t know how to do it, here’s a short guide: The recycle mark can be added to your model in PrusaSlicer as a part, modifier, or negative volume (recommended). Simply click on the selected object with the right mouse button, then choose “add negative volume” and pick an adequate recycle mark from the gallery.

Finally, there are many other ways of reducing the price and environmental impact of 3D printing. However, the most effective methods are rather complicated in home conditions. And yet, there are people who are able to make their own recycled filament out of failed prints. It might be a good idea to contact a local “lab” or workshop, where people often work on various projects that are too large or difficult to do at home. Plus, these facilities are often well-equipped for advanced projects. Some of them may even have various projects for collecting and reusing waste from 3D printing. For example, one of such projects turns waste from 3D printing into stylish furniture. Here in PrusaLab, we work on several internal projects but we’re always working on something new and if it turns out to be good for the public, we’ll let you know for sure.

Examples of various ways to recycle 3D printing waste: Furniture parts and recycled skateboards.

Unfortunately, recycling is quite difficult in the world of 3D printing. Rather than focusing on reusing garbage, it’s better to prevent making garbage in the first place. Still, it requires some creative thinking, which is obviously something that the whole community excels in. If you have any ideas, make them happen and share them with others. Every idea counts!

Happy printing!

In the world of 3D printing, filament is like ink for your printer. The choice of filament can significantly impact both the cost and quality of your 3D-printed objects. With many filaments available, each with unique properties and price points, understanding the factors that influence filament pricing can help you make informed decisions.

The Basics of 3D Printing Filament

Before diving into filament pricing, let's understand the basics of 3D printing filament. The filament is the thermoplastic material melted and extruded by your 3D printer to create objects layer by layer. It comes in various types, each with distinct properties and characteristics.

Common Types of 3D Printing Filaments

Some of the most common types of filaments include:

• PLA (Polylactic Acid): Known for its ease of use, biodegradability, and wide range of available colors.
• ABS (Acrylonitrile Butadiene Styrene): Offers durability, impact resistance, and heat resistance, making it suitable for functional parts.
• PETG (Polyethylene Terephthalate Glycol): Combines the benefits of PLA and ABS, providing good strength, flexibility, and chemical resistance.

These are just a few examples from the wide range of filament options, which also include specialty materials like flexible, composite, and conductive filaments, each with unique properties and applications.

Filament Diameters and Compatibility

Filament comes in different diameters to fit various 3D printers. The most common diameters are 1.75mm and 2.85mm (also known as 3.00mm). Choose the correct diameter compatible with your printer to ensure smooth and reliable printing.

Factors Influencing 3D Filament Cost

Now that we understand the basics of 3D printing filament let's explore the key factors influencing its cost.

Material Type of 3D Filament

The material used to make the filament significantly affects its price. Standard materials like PLA and ABS are more affordable than specialty filaments like flexible TPU, composite materials with carbon fiber or metal particles, and conductive filaments. These specialty filaments often have a higher price due to their unique properties and advanced manufacturing processes.

3D Filament Diameter and Tolerance

Filament diameter can also affect cost. 1.75mm filaments are typically more expensive than 2.85mm/3.00mm ones. Filament tolerance, which refers to the consistency and accuracy of its diameter along the spool, impacts print quality and price. Higher-quality filaments with tighter tolerances tend to be more expensive.

Spool Size and Weight

Filament is sold in spools, and the size and weight of these spools influence the overall cost. Common spool sizes range from 0.5kg to 2kg, with 1kg being the most popular. Larger spools often have a lower price per kilogram than smaller spools. Consider your usage requirements and storage capacity when deciding on spool size.

Manufacturing Quality and Brand

Manufacturing process quality and brand reputation also impact price. Premium brands invest in advanced production techniques, strict quality control, and extensive research and development to create high-quality filaments, contributing to a higher price compared to budget options. Strike a balance between cost and quality, as low-quality filament can lead to poor print results and potential printer damage.

Average Prices of 3D Filament

The average prices of filament vary depending on the material type, brand, and other factors discussed earlier. Here's a general overview of the price ranges for some popular filament types:

• PLA: $15 to $40 per kilogram
• ABS: $20 to $55 per kilogram
• PETG: $20 to $40 per kilogram

These are rough estimates, and prices can fluctuate based on market trends, seasonal promotions, and other variables.

Price per Kilogram vs. Price per Meter

When comparing filament prices, consider both the price per kilogram and the price per meter. The price per kilogram provides a general idea of the overall cost, while the price per meter takes into account the filament's density and diameter, giving you a more accurate representation of the actual cost per printed object.

How to Calculate Your 3D Filament Needs and Costs

To make informed decisions about filament purchases, estimate your filament usage for typical projects and calculate the associated costs.

Estimating 3D Filament Usage

Consider the size and complexity of your 3D printed objects, as well as the infill percentage and layer height settings you typically use. These factors will impact the amount of filament needed for each print.

Software Tools and Resources

Various software tools and online resources can help you estimate filament usage and costs. Slicing software often includes features that calculate the amount of filament needed for a specific model based on your print settings. Online filament calculators can also provide quick estimates based on the dimensions and settings of your print.

Tips for Minimizing 3D Filament Waste

To reduce expenses, it's important to minimize filament waste. Some tips include:

• Properly calibrating your 3D printer to ensure accurate extrusion
• Optimizing print settings to minimize unnecessary filament usage
• Using support structures sparingly and designing models to minimize the need for supports
• Recycling and reusing filament scraps when possible

By following these tips and using estimation tools, you can better understand your filament needs and costs, helping you make informed purchasing decisions.

Where to Buy 3D Printing Filament

When purchasing 3D printing filament, you have several options available.

Online Retailers vs. Local Suppliers

Online retailers offer a wide selection of filaments from various brands, often at competitive prices. They provide the convenience of shopping from home and the ability to compare prices and read customer reviews easily.

Local suppliers, such as 3D printing stores or hobby shops, offer the advantage of seeing and touching the filament in person before making a purchase. They can also provide valuable advice and immediate support if needed. However, local selection may be limited compared to online options.

How to Save Money on 3D Filament

While quality should be a top priority, there are several strategies to save money on filament without compromising your 3D printing results.

Purchasing in Bulk or During Sales

Buying filament in bulk or during sales events can result in significant savings. Many retailers offer discounts for larger orders or periodic promotions, like QiDi's "Buy 2, get 15% off; Buy 3, get 20% off" deal. Look for these opportunities to stock up on your preferred filaments at a lower cost.

Joining Maker Spaces or Community Groups

Joining local maker spaces or 3D printing community groups can provide access to shared resources and bulk purchasing opportunities. These communities often negotiate group discounts with suppliers, allowing members to benefit from lower prices on filament and other supplies.

Recycling and Reusing Filament Scraps

Don't waste filament scraps! Many enthusiasts find creative ways to recycle and reuse leftover filament, such as creating multicolored prints by fusing scraps together or using them for small test prints or calibration objects. Repurposing scraps can help you get the most value out of your materials.

Beyond the Price Tag - Value Considerations

While cost is important when choosing a 3D printing filament, consider the long-term value and impact on your 3D printing experience.

Filament Quality and Print Success

High-quality 3d printing filaments can significantly improve the success rate of your 3D prints. Poor-quality filament can cause issues like inconsistent extrusion, clogging, warping, and poor layer adhesion, resulting in failed prints and wasted time and materials. Investing in reliable, high-quality filament can save you from frustration and additional costs.

Long-Term Costs of Low-Quality Filament

Low-quality filament may seem like a cost-saving option upfront but can lead to higher long-term costs. Frequent print failures, reduced print quality, and potential damage to your 3D printer can result in increased expenses over time. Consider the total cost of ownership, including potential replacements, repairs, and lost productivity.
