How to choose between resin and filament 3D printers?

Understanding the basics of resin and filament 3D printers

If you’re stepping into the realm of 3D printing, you’re likely weighing your options between resin and filament printers. Each has its own set of quirks and perks, catering to different needs and projects. Resin printers, also known as SLA or DLP printers, use a liquid resin that hardens when exposed to light. This method is renowned for its ability to produce highly detailed prints, making it ideal for applications where precision is paramount, such as dental or medical models. The resin cures layer by layer, allowing for incredibly smooth finishes.

On the flip side, filament printers, often referred to as FDM printers, use spools of thermoplastic filament that are extruded through a heated nozzle. This technique is more about building up the object layer by layer and is typically the go-to for larger prints or when working with robust materials like ABS or PLA. Filament 3D printers are beloved for their versatility and ability to produce functional prototypes and parts, making them a favourite in industries like automotive and aerospace. Understanding these fundamental differences is the first step in your 3D printing journey.

Cost comparison: Resin vs filament printers

When it comes to cost, both initial investment and ongoing expenses come into play. Resin printers generally have a higher upfront cost due to the technology involved. The resins used can also be pricier than filament, especially if you’re looking for speciality resins for specific applications. However, they often justify the cost with the level of detail and quality they provide.

Filament printers, on the other hand, can be more budget-friendly to start with. Filaments are usually cheaper and more readily available, making them an attractive choice for hobbyists or those just diving into 3D printing. That said, the cost can vary widely depending on the printer’s capabilities and the type of filament used.

Print quality and detail: Which is better?

When quality and detail are the top priorities, resin printers often take the cake. They excel in creating intricate details and smooth surfaces, thanks to their high-resolution capabilities. This makes them perfect for applications that demand precision, like jewellery making or miniatures. The layer lines are virtually non-existent, providing a finish that’s hard to achieve with filament printers.

Filament printers, while not as finely detailed as their resin counterparts, are continually improving. They offer a robust solution for larger objects where minute detail might not be as crucial. With advances in technology, filament printers can still produce high-quality prints, especially when paired with the right settings and materials. It’s worth considering your project’s specific needs and whether the detail level is a deal-breaker.

Ease of use and maintenance

Ease of use can be a significant deciding factor, especially for beginners. Filament printers often win points here, as they’re generally more straightforward to set up and use. The process of loading filament and starting a print is typically less messy and more intuitive. Maintenance is also relatively low-key, involving routine cleaning and occasional part replacements.

Resin printers, while offering higher detail, come with a steeper learning curve. Handling resin can be tricky, requiring careful attention to safety and cleanliness. Post-processing is also a must, as prints need to be washed and cured after printing. Maintenance involves regular cleaning of the resin vat and ensuring the printer’s optical path is clear. For those willing to invest the time and effort, the results can be well worth it.

Environmental and safety considerations

Safety and environmental impact are important considerations in today’s world. Resin printing involves handling chemicals that can be hazardous if not managed properly. It’s crucial to use protective gear, like gloves and masks, and ensure adequate ventilation when working with resin. Disposal of unused resin and washed liquids needs to be done responsibly to minimize environmental harm.

Filament printers generally pose fewer safety risks. The primary concerns are the fumes emitted when printing with certain filaments, which can be mitigated with proper ventilation. Filaments like PLA are biodegradable, offering a more eco-friendly option. However, it’s essential to consider the full lifecycle of the materials used, including production and disposal, to fully understand their environmental impact.

In wrapping up, whether you’re leaning towards a resin or filament 3D printer, it boils down to your specific needs and preferences. Resin might be your best bet if precision is key, while filament could be more fitting for larger, functional prints. If you’re still on the fence, why not get in touch with us at Ergometa?
