WEAK INFILL

WEAK INFILL

Infill is an important parameter to consider while printing. If not carefully managed, it can cause problems in 3D printing. The infill density and pattern play an important role in the strength of the parts. It also dictates the stability & shape of the model. So, it is important that the infill is carefully selected and used.

Check out the following 3D printing troubleshooting tips to know how to resolve a weak infill problem in 3D printing.

• Set Optimum Print Speed

This is one of the first troubleshooting solutions, for a weak infill. It is widely known that print speed is an important factor affecting the infill. Generally, new users do not ascertain enough importance to the infill and tend to print the infill at faster speeds. This is a grave error on the part of the user. As mentioned above, the infill serves many purposes and it should be printed with as much precision as the other layers. So, the print speed should be adjusted and generally printed at low speeds. This can be easily resolved through a trial & error method. Remember that a strong infill will add to the strength of the printed part.

• Check Extrusion Width

Extrusion width settings can really be leveraged when printing infills. Users make the mistake of not playing with the extrusion width. Generally, the extrusion width is ignored and kept the same for the entire print. This robs the users of a very powerful tool to improve the print strength. By printing the infill with larger extrusion width, the infill can be substantially stronger.

This again is a trial & error method as there is no ideal figure for the width. Just remember that increasing the infill extrusion width will also increase the amount of material deposited and so if the model is small then the infill pattern may overlap. So, it should be tried only with bigger models.

• Use Appropriate Infill Pattern

Experiment with the infill pattern. Some infill patterns are stronger than others while others are easy to remove. So, experimenting with the available infill pattern in the slicing software will also help in eliminating the problem of weak infill.
