The MakerBot MinFill is the all new print mode in MakerBot Print, MinFill prints 30% faster using 30% less filament. This is a breakthrough slicing algorithm and it means you can take your ideas from inspiration to innovation faster, as a new print mode in MakerBot Print, MinFill prints models that have a larger internal volume faster without sacrificing surface quality.


How MinFill Works


Infill is the support structure inside your 3D print model that’s printed as a pattern. Most objects cant be 3D printed without it, the infill holds up the outer layers of your print, as well as the final roof layers. The more infill you have, the more solid and durable your 3D print will be, however the more printing with infill the more filament needs to be used and the longer it will take.


With most 3D printing software out there you can adjust the percentage of the infill, however infill is always printed evenly throughout the entire object, meaning it’s even printed in areas that don’t necessarily require infill for structural support. This can make 3D printing very inefficient, so MakerBot wanted to challenge the idea that all prints must have an infill pattern. MakerBot developed the engine behind MinFill – it’s intelligent slicer algorithm.


MinFill streamlines supports inside your 3D print, this advanced algorithm automatically analyses a 3D model to learn where infill is needed. Depending on the geometry of your design, MinFill will build the smallest possible support structures inside your print. MinFill decides on the shape, placement and density of the infill, only printing in areas that require structural support, such as roofs and certain types of walls.


How MinFill differs to other infill settings is it decides if you print needs internal structures at all, if none are required, it prints none. MinFill will do so for each and every print without sacrificing surface print quality or appearance. MinFill is the only solution that applies to all geometries without requiring users to make manual adjustments in their printing software.


Faster and Cheaper!


As MinFill uses the minimum infill possible, its value lies in printing models with a larger internal volume. Smaller models are more likely to print fast with MinFill, but the greater the internal volume of a print, the more time and filament you can save.


Based on MakerBot’s testing, MinFill on average prints 30% faster using 30% less filament.



Faster Iterations!


MinFill further accelerates the design process by dramatically speeding up iterations that are part of early concept modelling, with each iteration you can print models faster and quickly evaluate your designs. With the added speed and cost savings MiniFill is ideal for printing iterative form study models. You are able to evaluate the fundamentals of a design, such as its overall form, size, proportions and surface quality. For these types of models print speed is more critical than structural strength, each iteration only needs to hold up to the very minimal pressure of the designer holding the model, as a result it’s unnecessary to fill the entire model with infill.


In a busy environment, the faster you can print, the more projects a team can complete.
