FDM 3D Printing Tutors & Freelance Services: 1-on-1 Training

When handling resin in 3D printing, ensure you wear nitrile gloves and protective eyewear, work in a well-ventilated area, avoid direct skin contact, and immediately clean any spills with isopropyl alcohol. After printing, cure the resin model properly and dispose of waste resin and contaminated materials according to local regulations.

FDM 3D printers commonly use materials such as PLA, ABS, PETG, TPU, and nylon, while resin 3D printers typically use photopolymer resins, including standard, flexible, tough, and high-detail resins.

For FDM prints: 1. Check the filament for tangles or breaks. 2. Ensure the print bed is level and clean. 3. Verify that the nozzle is not clogged. 4. Adjust the print temperature and speed settings. 5. Confirm filament type matches the print settings. 6. Look for any loose hardware or belts on the printer. 7. Update printer firmware and slicer software. 8. Calibrate the extruder steps per mm. For resin prints: 1. Ensure the build

Choose FDM (Fused Deposition Modeling) for larger, functional parts and projects requiring durability and lower costs; opt for Resin (SLA/DLP) 3D printing for highly detailed, intricate designs, smooth finishes, and projects where precision is critical.

FDM printers typically have lower print resolution, usually around 50–200 microns, while resin printers can achieve much finer details, often providing resolutions as low as 25–50 microns.

For FDM prints, start by removing the print from the build plate and carefully pealing off any support structures with pliers. Use sandpaper of varying grits (starting coarse and moving to fine) to smooth the surface, optionally applying a primer and paint for a polished finish. For resin prints, detach the model from the build platform and remove any supports using snippers, then wash the print in isopropyl alcohol (IPA) to remove uncured resin. Cure the model under UV

To level the print bed on an FDM 3D printer, follow these steps: 1. Preheat the bed and nozzle to printing temperature to account for thermal expansion. 2. Disable the stepper motors to allow manual movement of the print head. 3. Use a piece of paper or a feeler gauge to check the distance between the nozzle and the bed at each corner. 4. Adjust the bed height at each corner using the leveling knobs until you feel slight resistance while moving the paper or

The time to complete a 3D print with FDM or resin printing can vary widely depending on the size, complexity, layer height, and infill density of the model, but typically ranges from a few hours to several days.

FDM printers require regular calibration, nozzle cleaning, and bed leveling, while resin printers need consistent cleaning of the resin vat and build plate, as well as periodic replacement of the FEP film.

To calibrate your FDM 3D printer, you should: 1. Level the bed using the manual adjustment screws or an automatic bed leveling sensor. 2. Adjust the nozzle height using feeler gauge or paper to ensure it's at an optimal distance from the bed. 3. Calibrate the extruder by ensuring filament flow matches prescribed settings; measure and adjust using the printer's firmware. 4. Perform test prints and fine-tune parameters such as temperature, print speed, and retraction settings to
