From an idea to a physical object - the first steps in 3D printing
Printing the first model is an exciting moment - it's the moment when your idea becomes a tangible reality. Regardless of whether you are completely new to 3D printing or have already explored this technology, this guide will help you successfully go through the entire process - from model selection to the finished object.
1. Choose a simple model
For a first try, it's best to choose something simple:
- Cable holder
- Pendant
- Small figurine
- Desk organizer
Such models are quickly printed, do not require support and are easy to prepare.
Where to find them?
- MakerWorld - especially useful if you use a Bambu Lab printer
- Thigeverse
- Printables.com
2. Prepare the model in slicer software
Slicer is a program that converts a 3D model (most often in STL format) into instructions that the printer can understand (G-code).
For beginners we recommend:
- Bambu Studio - if you use the Bambu Lab printer, the software is simple, visually clear and automatically adjusts the parameters
- Cura – universal and free, with many supported printers
In the slicer you will:
- Import model
- Adjust the print quality (eg layer height - 0.2/0.16/0.12mm)
- Select material (eg PLA/PETG)
- Add supports if needed
- Place the model on the virtual surface
Most modern slicers have preset profiles for printers and materials, so you don't need to know the technical details.
3. Prepare the printer
Before printing, check the following:
- Is the printer leveled correctly?
Most modern printers, including Bambu Lab models, have automatic leveling. - Are the substrate and filament inserted correctly?
Insert the PLA roll and check that it is properly extruded through the nozzle. - Is the surface clean?
Remove dust or residue from previous prints. - Is the printer connected to a computer or application?
With Wi-Fi enabled printers, the file can be sent directly from the slicer.
4. Start printing
When you send the file to the printer, it will warm up and start printing. Follow the first few layers - that's the most important part. If the model adheres well to the substrate and the layers are even, the print will most likely be successful.
With printers that have additional sensors (eg Bambu Lab X1-Carbon), the system can automatically check the quality of the first layer and warn you if something is wrong.
5. Model removal and finishing
When printing is finished:
- Wait for the substrate to cool down.
- Carefully remove the model (use a spatula if necessary)
- Remove supports if any
- If desired, process the edges with sandpaper or a scalpel
6. What if something goes wrong?
Mistakes are part of the learning process. The most common are:
- The model does not stick to the substrate → check the leveling and use the "brim" option
- Finishing (stringing) → reduce the temperature of the extruder
- Deformations → use a quality filament and check that the nozzle is clean
Most problems are easily solved with basic tips and a little patience.
7. Next steps
Once you've mastered the first model, you can:
- Explore new materials (TPU, ABS)
- Learn 3D modeling (eg Tinkercad)
- Experiment with multi-color printing
- Share your work with the community
Conclusion
Printing your first model doesn't have to be complicated. With a good selection of 3D printers, simple software and a quality model, you can make your first 3D object today. If you use a 3D printer that is designed for ease of use - such as the Bambu Lab devices - the whole process will be even more enjoyable.
