Exploring Cost-Effective Options for Filament in the World of 3D Printing

The 3D printing industry is experiencing a surge in low volume manufacturing, a practice that differs from traditional mass manufacturing due to the production of smaller quantities of parts. While large-scale approaches may be financially infeasible for low volume manufacturing, 3D printing offers an ideal solution with its ability to print parts right away without the need for tooling. This, coupled with the availability of affordable desktop FFF 3D printers, has led to the emergence of numerous small-scale manufacturing operations.

Despite the relative slowness of individual 3D printers, an array of these printers can collectively produce significant quantities of parts through parallel operation. This contrasts with mass manufacturing, where a few injection molds quickly create parts, but the cost of creating those molds can be prohibitively expensive. As a result, small 3D print farms have surfaced in various locations, some catering to requests from those in need of parts, while others focus on producing their own parts in larger quantities.

Take, for instance, a craft designer on Etsy who utilizes 3D printing to create parts on demand for their online shop. This growing trend has given rise to new software solutions crafted specifically for managing arrays of 3D printers. Among the notable industry players in this field is 3DQue, with their software suite designed to support 3D printer farms. In fact, 3DQue’s service integrates seamlessly with popular e-commerce platforms like Shopify and Etsy, highlighting the tangible reality of this phenomenon.

Once a 3D print farm is established, the major ongoing cost, besides acquiring the machines, is acquiring materials. Therefore, it becomes crucial to source filament at the lowest possible cost. Fortunately, there are two viable approaches to achieving this goal.

The first approach involves finding the lowest cost per kilogram of filament. Online sources now offer filament options of reputable quality starting as low as US$15 per kg, a significant drop from the prices of only a few years ago, which ranged between US$20-25 per kg. This approach is suitable for individuals or small-scale operations with a single 3D printer.

The second approach involves purchasing filament in larger quantities, assuming there is a level of confidence in its usage. However, most online sources only sell filament in single spools, primarily catering to individual customers. Nevertheless, outlets specializing in bulk filament purchases do exist, and a select few consumer-oriented shops offer volume discounts.

One such outlet is Matterhackers, where their house filament can be purchased for as low as US$16 per kg when buying more than 12 spools. Another option is IC3D, which offers 10kg spools at a lower per-gram cost compared to 1kg spools. For those consuming large quantities of filament, 3D-Fuel provides discounted pricing starting from 10kg per month, with potential savings of up to 35% for orders surpassing 1000kg per month.

Moreover, it’s worth exploring the possibility that sources selling individual spools may have hidden offers for bulk purchases. It never hurts to reach out and inquire about such possibilities. By uncovering untapped resources, small 3D print farms can optimize their costs and enhance their overall efficiency.

In conclusion, the world of 3D printing presents several avenues for reducing the cost of filament. Whether it be by finding the lowest individual cost per spool or purchasing larger quantities from specialized outlets or even seeking out potential bulk discounts, there are viable options available to support the sustainable growth and success of 3D print farms.
