Which Technology is Best For 3D Printing Miniatures ?

 3D printing technologies have come a long way, with a proven ability to provide small features with high-quality detail. This has led gaming communities like Dungeons & Dragons and war hammer 40K players, to start adopting 3D printing to create personalized pieces.

These epic role-playing tabletop games typically include vaarious terrains, unique structures, and small character pieces shoscasing intense and intricate details. Whilemany consider these board games fun and entertaining, the game pieces can be pricey, meading serious gamers to shell out hundreds (if not thousands) of dollars on miniatures ans accessories.

Wheter you're a gamer wanting to add some unique pieces or are in the production industry and need to produce hundreds or thousands of a single unit, shoosing the correct 3D printing technology will help you get the highest quality of print necessary without breaking the bank.

Note. Although there are many different 3D Printing technologies, this article will focus solely on FDM and Resin-based equipment.

WHAT4S THE DIFFERENCE BETWEEN, FDM, PROGRAMMABLE PHOTOPOLYMERIZATION, SLA & POLYJET ?

Fused Deposition Modeling (FDM), is an additive manufacturing technology developed by Scott Crump, co-founder of Steatasys. FDM technology uses a continuous strand of filament of various thermoplastic materials, and fed to the heated extruder head to be extruded in thin layers (around 200 microns) driven by a computer-controlled coordinate system to create the desired model.

Resin 3D printers use a liquid-based composition of various thermoset epoxies and/or acrylics that, when exposed to UV light, rapidly convert to a solid polymer. Resin 3D printers also print layer by layer, but deliver parts with more detail thinks to a much higher layer resulution (about 50 microns).

The Origin One DLP resin 3D Printer (powered by Programmable Photopolymerization technology) uses a tightly synchronized print process with pneumatic controls to reduce pull forces during production, producing parts with exceptional surface quality.

Large stereolithography resin 3D printers, likde the Neo 450 and 800, can build hundreds of miniature pieces in a single build. These resin technologies are particularly useful for prototyping parts intended to be painted (like miniatures and terrain), becouse the models can accept the same materials and processes as the ennd product.

Polyjet technology offers similar benefits with similar materials, but prints with even higher resolution (about 25 microns) and supports full-color printing without the need to paint. BUT THAT4S A SUBJECT FOR ANOTHER ARTICLE.

CONSIDEERATIONS

PRINT QUALITY

What are you trying to print and how much detail is needed ? The scale of the object will also affect the amount of detail the printer is capable of. FDM machines typically have a bigger build volume, are amount of detail the printer is capable of. FDM machines typically have a bigger build volume, are easier to use, and come with a more entry-level price tag. While a properly tuned FDM printer can offer grear detail, you will still see the layer lines and stepping from the inherent resolution of the technology.

PRINTING VOLUME & TIME

If you don't need high-quality details with small features, such as large trees or building structures, you can save money going with FDM.

Resin printers often have smaller build bays than FDM, but they typically print at nearly the same speed, regardless of the number of parts ---decreasing the overall price-per-part when printing multiple miniature characters at once. And, large Stereolithography printers can produce hundreds of parts on a single build tray

MATERIAL TYPES & COSTS

PLA and ABS are two commonly used FDM materials due to their useability and affordability.

Consumer FDM filament spools of PLA or ABS can be purchased for as low as 20 $ for a 1 Kg spool, up to 100 $/Kg or more for production quality material.

General purpose consumer resin is found to be about 50 $ fir a 1L bottle, ranging to 100 $/L for professional grade materials. However, resin printers often have other associated costs that must be addressed, such as replacing a resin tank, having a large supply of iIsopropyl alcohol, as well as UV lamps and other protective equipment.

WORKING PROCESS

Both FDM and resin technologies require support structures to ensure part quality, wwhich must be removed after printing. FDM supports may be removed by hand and discaded, but some support materials are dissolvable in water or detergent for hand-free removal. This mrocess is similar for resin technologies, whech rely on scaffold structures made of the same model material: carefully remove as much as possible by hand and with tools, then soak the parts in an ultrasonic cleaning solution tank that disolves the remaining support material.

WHICH TECHNOLOGY IS BEST FOR PRINTING MINIATURES ?  

For large parts, FDM printers are very capable of producing impressive detail when build parameters are properly estabilished. If you are new to 3D printing, you may want to consider an FDM machine like a MakerBot Method becouse of the lower cost and ease-of-use. For commercial/industrial purposes, Strataysys offerss a host of large reliable and precuise printers.

For next-level detail, large volumes, and fine-tuned models, DLP and Stereolithography resin teechnologies deliver every time.
