"U Forge: Layered Printing Tips and Tricks"

  • For most images, a layer height of 0.08 and 0.04 is recommended, with a 0.4 nozzle working well at 0.04, potentially needing to slow down on high-speed printers.
  • Utilize profiles for 0.5 or 0.7 layer heights if available on your printer, informing the software accordingly.
  • Complex images often require only seven or eight colors, with the possibility of reusing colors multiple times to create depth.
  • U Forge's layered prints resemble oil paintings due to their depth, enhancing the visual appeal.
  • U Forge's layer-based nature restricts the use of CMYK filaments for color blending, as colors cannot be stacked or rearranged within layers.
  • A printer allowing filament changes mid-print is essential for creating multi-colored prints, with an average of five swaps being manageable.
  • To start using U Forge, purchase the software for $118, import your image, assign colors, and adjust sliders to achieve the desired look before printing.
  • Commercial licenses for selling prints are available at different price points, with annual fees ranging from $45 to $100, or a lifetime option for $250.
  • U Forge users often embrace a contrasty style over photorealism due to medium limitations, with challenges in achieving realistic depth and accurate color perception.
  • The upcoming U Forge version will introduce a color match feature, allowing users to define colors and have the mesh built based on the closest matching colors in their palette.

"Outdoor Material Testing: PLA vs Carbon Fiber"

  • Experiment involved testing various materials for outdoor use, including PLA, PTGs, nylons, and carbon fiber, with observations on degradation and brittleness.
  • PLA materials were found to be brittle and degraded quickly, while carbon fiber-based ones were recommended for outdoor use due to their durability.
  • The experimenter used a standard chip design for consistency in testing, with controlled factors and simultaneous printing of materials for comparison, sharing results on YouTube and offering a detailed report for sale.
