Mistake 1: Printing With the Wrong Resolution
The resolution of your 3D printer significantly affects the quality of your 3D printed minis. A common beginner mistake is printing at a very high resolution, believing it will result in a better quality print. While this might be valid for large-scale models, it is not the same case with miniature models.
By printing minis at a high resolution (lower layer height), the printer will produce more layers, thus more opportunities for errors to occur. Plus, the added time can notably increase the likelihood of filament issues, like jams or breaks. Ideally, you should print minis at a resolution between 50 and 100 microns. This will give a good balance of surface detail and structural strength, with a reasonable print time.
Mistake 2: Ignoring Support Structures
When it comes to 3D printing minis, neglecting support structures is a prevalent error. Novices often assume their models will print seamlessly without the need for these supports. However, with 3D printed minis, overhangs and complex geometry can cause the filament to sag, leading to a lack of definition and warped minis.
Always examine your 3D model thoroughly before printing, making sure to add necessary supports, particularly under overhangs. There are two primary types of support: tree-like supports ideal for intricate designs, and block supports, which are better for larger, sturdier sections. Learning to add appropriate supports is crucial to achieve high-quality 3D printed minis.
Mistake 3: Incorrect Bed Leveling
Failure to level the print bed correctly leads to a host of issues that compromise the quality of 3D printed minis. If the bed is too low, the initial layer may not adhere properly, leading to prints coming off during the process. Conversely, if the bed is too high, it can end in blocked nozzles or poor print quality.
Regularly check to ensure that your 3D printer’s bed is leveled before initiating your print. This simple practice can significantly reduce the likelihood of printing problems, contributing to a much smoother, less problematic 3D printing experience.
Mistake 4: Wrong Filament Type
Choosing the wrong filament material can ruin your mini’s aesthetics and durability. Popular filaments like PLA and ABS have different properties suitable for different designs. PLA is excellent for beginners due to its ease of use, but it may not offer the strength needed for intricate designs. ABS, while stronger, requires careful temperature management to prevent warping and shrinkage.
For intricate miniature designs, consider using resin printers which provide greater detail than filament printers. Whatever material you choose, make sure it is appropriate for the task at hand, taking into account factors such as design complexity, intended use, and the capabilities of your 3D printer.
Mistake 5: Inadequate Post-Processing
Post-processing is crucial for achieving a great finish on your 3D printed minis. This includes removing any supports, smoothing rough surfaces, and applying paint or finish. Neglecting this step can result in an unprofessional appearance, with visible print lines and rough patches.
Use tools like needle files, sandpaper, and cutting pliers to gently remove support structures and smooth the model surface. If you’re painting your model, priming it will make sure the paint adheres better and lasts longer. Make sure you undertake post-processing in a well-ventilated area, use protective gear, and clean up any residue to ensure safe and effective results.
Mistake 6: Rushing Prints
Impatience is a common blunder among novices in 3D printing. Wanting to see finished products quickly often results in setting higher printing speeds. Unfortunately, this can negatively impact the quality of the minis, causing issues like layer misalignment, extrusion errors, and poor surface finish.
Remember that 3D printing is a gradual process. Premium quality minis require time and meticulous attention to detail. Economizing on time often equates to compromising on quality. For beautiful, quality 3D printed minis, it is recommended to set your printer speed between 30-50mm/s.
Conclusion
Avoiding these six common beginner mistakes can greatly enhance the quality of your 3D printed minis. Along with these, it’s equally paramount to familiarize yourself with your 3D printer’s specific build, interface, and calibrations. Consistently creating appealing and durable minis requires patience, but the reward of holding your very own, error-free, 3D printed creation makes it all worthwhile.
