  • Creality LD-002R LCD Resin 3D Printer

    Features

    • “BUILD AND MOTION: Great emphasis is being placed on the LD-002R’s robust build quality and the components of its motion system, which is underpinned by a ball screw and single linear rail for the Z-axis.
    •  ANTI-ALIASING: MSLA 3D printers use an LCD screen to mask an image of a layer over a UV light source. Comprised of hundreds of thousands of pixels, each a little rectangle itself, this tech leaves a telltale sign of the edges of these pixels on the print surface. Often barely visible, this effect can be lessened through the use of a digital processing called anti-aliasing, which interpolates between these edges, smoothing the effect out.
    •  QUICK LEVELING: Quick leveling in the sense that the machine will lower the print plate to the vat for you, yes the LD-002R is quick leveling. Four hex screws feature on the print plate — loosen them before dropping the plate, and it will align to the level of the screen. Tighten and you’re good to go. Standard MSLA fare.
    •  PERFORATED PRINT PLATE: Something of an oddity on a small desktop MSLA machine, the Creality LD-002R 3d printer has a perforated print plate. Typically seen on larger bottom-up machines where larger prints present additional pull that might dislodge an improperly adhered print, it’s unusual, and perhaps even distracting overkill, to see it on a smaller machine. It’s not a bad thing, but it makes you wonder why they did it.
    •  AIR FILTER: A small box at the rear of the print chamber contains a pouch of activated carbon. This should help to remove part of the stench of exposed resin from the air.
  • Creality Ender 3 Neo FDM 3D Printer

    FEATURES-

    • 1. CR Touch for Easier Leveling- Self-developed CR Touch empowers auto-leveling by adjusting the height between the nozzle and platform, making leveling easier and more accurate.
    •  2. Enjoy Quiet Printing- With a silent mainboard, low decibel has less impact on study or work, creating cozy printing atmosphere
    •  3. Quick Heat Dissipation- The corrugated heat sink enlarges the radiating area. Quick heat dissipation vastly reduces the risk of tube blockage.
    •  4. Full-metal Extruder for Smooth Feeding- The full-mental extruder is more durable. The stronger extrusion force enables smooth feeding.
    •  5. Hands-on Fun: Independently assemble the printer and have fun. Modify a 3D printer, enjoy DIY.
    •  6. Reliable Printing with Durable Build Surface: Durable carborundum build surface featured by even heating reduces the risk of warping. Strong adhesion ensures the stability and quality of the print.
    •  7. Steadiness Enhanced by Mold Springs: Alloy steel mold springs of good toughness give better support to the platform, guaranteeing the printing quality.
    •  8. No Fear of Outage: The resume printing function can accurately record the data and can resume the print from where it’s left off, avoiding printing failure and material wasting.
