  • Page 43 WuxnSlicer Tips How do I print larger models? To print larger models, break them down into smaller parts and connect them using fasteners, joints, or adhesives. Utilize WuxnSlicer to divide the model by positioning it below the build surface. Select the 'Slice' option to generate a G-code for one portion of the model, then repeat the process for the remaining parts.
  • Page 44 WuxnSlicer Tips What is Support Material? As a 3D part is printed layer-by-layer the filament must be supported or it will fall due to the force of gravity. We can enable Support Material as a sacrificial part to “prop up” the geometries that form bridges or overhangs. WuxnSlicer automatically pinpoints the areas of your 3D model that require support material, and highlights them in red for easy identification.

  • Page 45: Materials

    Materials In FDM (Fused Deposition Modeling) 3D printing, filaments are the thermoplastic materials that are used as the "ink" for the printer. The filament is loaded into the printer and is melted by a heating element, and then extruded through a nozzle to build up the object layer by layer.
  • Page 46 Materials PLA (Polylactic Acid) PLA is a biodegradable thermoplastic polymer made from natural resources such as corn starch, sugarcane, or other types of starch. PLA is the most widely used filaments in 3D printing because it is easy to use and produces high-quality prints. PLA filament is non-toxic, has a low melting point, and produces minimal odor when printing.
  • Page 47 Materials PETG (Polyethylene terephthalate glycol) PETG is a type of thermoplastic polymer filament that is commonly used in 3D printing. It is a strong, durable, and has high thermal resistance. One of the main advantages of PETG filament is its strength and flexibility. It is stronger than PLA and is also more flexible, which makes it a good choice for parts that need to withstand high stress and pressure.
  • Page 48 Materials (Acrylonitrile Styrene Acrylate) ASA is a thermoplastic filament that is becoming more popular. It is known for its weather resistance, high UV resistance and high impact strength. ASA has similar printing characteristics to ABS but with improved resistance to environmental factors such as sunlight, heat, and moisture.
  • Page 49 Materials ABS (Acrylonitrile Butadiene Styrene) ABS filament is known for its toughness, strength, and heat resistance. It is a good choice for various 3D printing applications including toys, phone cases, and automotive parts. However, ABS filament is known to produce unpleasant odors during printing. Also, ABS filament is difficult to print with because it is prone to warping and layer separation.
  • Page 50 Materials (Thermoplastic Polyurethane) TPU filament is a type of flexible and durable thermoplastic material. It is known for its high elasticity, impact resistance, and toughness. It is often used to create flexible parts such as phone cases and footwear components. TPU filament is also resistant to oils, chemicals, and UV light, making it a versatile material for a range of applications.
  • Page 51 Materials PA (Polyamide) Polyamide (PA) filament, also known as Nylon filament, is a thermoplastic material commonly used for 3D printing. It is a strong and durable material that is often used for industrial applications where high strength and impact resistance are required.
  • Page 52 Materials PC (Polycarbonate) PC filament is a strong thermoplastic characterized by its excellent impact resistance, high rigidity, heat resistance, and fire retardancy. It is ideal for harsh environments where materials are put to the test, meaning it can withstand extreme temperatures and pressures.
  • Page 53 It's worth noting that composites can be more abrasive and wear out your brass nozzle faster. We suggest upgrading your Wuxn WXR to a hardened steel nozzle to mitigate this. Some examples of composite materials are: PLA carbon fiber-reinforced - This material will print just like traditional PLA but offer improved strength.
  • Page 54 Material Storage Moisture from the air can affect 3D printing filaments, leading to brittleness, increased stringing, and voids in printed parts. For best results, store filament in a dry box with vacuum sealing, desiccants, and optional heating. If a dry box is not available, an oven can be used to heat the filament and remove moisture.
  • Page 55 Maintenance & Care Every Wuxn WXR is thoroughly inspected, fully assembled, and tested prior to shipment to ensure that it is ready to run straight out of the box. However, all mechanical systems will degrade over time and maintenance is required to keep your 3D printer functioning properly.
  • Page 56 Maintenance & Care Linear Guide Rail Lubrication The second most common item thats needs regular maintenance is the X and Y linear guide rails. It is best practice to lubricate the linear guide rails every 2-3 months with low viscosity oil. We highly recommend using Lucas Extreme Duty Gun Oil because of its low viscosity and needle nozzle applicator.
  • Page 57 Maintenance & Care Adjusting Belt Tension For best performance of the Wuxn WXR, certain belt tensions are required. Improper belt tension will result in layer shifting, ringing, or inconsistent sensorless homing. The belt tension for both the X and Y axis should be checked every 3-4 months.
  • Page 58 Maintenance & Care Z Wheel Tensioning The Z-axis motion of the Wuxn WXR is achieved with six “V” wheels. The inner wheel on each side has an eccentric nut that is used to adjust the tension. Use a 10mm wrench and turn this nut until you are just able to move that wheel smoothly with your finger.
  • Page 59 Maintenance & Care Replacing the Nozzle The Wuxn WXR comes standard with a 0.4mm brass nozzle. This nozzle will wear down over time and reduce the print quality. The nozzle should be replaced after printing with 100 - 200 kg of filament. When printing with composite materials we recommend upgrading to a hardened steel nozzle.

    This will result in a “wavy” like extrusion of filament. Solution: Use the Wuxn Wizard items “PID” and then “E-Steps” to calibrate the temperature and flow rate. This list is not exhaustive of all the print quality issues that may arise.
  • Page 62 Print Quality Issues ● Over-extrusion: This occurs when the printer extrudes too much filament, resulting in the printed object having thicker layers than intended. Solution: It can be caused by the extrusion multiplier being set too high, or by the nozzle being too close to the build plate. ●...
  • Page 63 Common Mechanical Issues Lead Screw Separation An issue that may occur with the Wuxn WXR is “lead screw coupler separation”. The lead screw coupler is composed of three components that may separate during shipment due to excessive forces and vibration.
