We have built one of the largest and fastest 3d-printers in the world. We call it The Box and it can build almost anything between the size of a pinball and a complete kitchen table. The bed area can fit details with a size of up to 1500x1100 mm with a maximum height of 1500 mm.
The Box uses FDM (fused deposition modeling) and granulates to reduce material costs whilst giving a wider range of plastics to choose from. It enables for a large variety of extruder heads to give the user more control over the printing resolution.
The Box is our new product and our vision of what the future should look like.
At BLB Industries, we feel that a 3d print should not be regarded as complete when it exits the machine. We would rather see the machine quickly sketch the print and leave the finer details to be treated afterwards. This is from an economic point of view.
For this comparison we will use the 1000% #3DBenchy that we have previously printed as a comparison product.
With a 0.3mm nozzle you would get every detail and a smooth surface finish. With this nozzle, the benchy would take 230 hours to print with a cost of approximately €13 000.
With a 1mm nozzle you would get all the details but with a rough surface. With this nozzle, the benchy would take 30 hours to print with a cost of approximately €1 700.
With a 2mm nozzle you would still get all the details but with a slightly more rough surface. With this nozzle, the benchy would take 9 hours to print with a cost of approximately €500.
With a 6mm nozzle you would start to loose a lot of details and the benchy would recieve a very rough surface.
The time to print as well as the cost continues to drop with increasing nozzle size all the way to a 6mm nozzle after which the price levels at €150.
We would recommend the 2mm nozzle since it is cheaper than the smaller nozzles without making a big difference to the surface finish.
If a smoother surface is required, this work could be performed manually after the print. Considering the price difference of around €12 500 between the 2mm nozzle and the 0.3mm nozzle in our example above, treating your prints rather than to having them ready from the machine could result in the savings of thousands of euros.
That is why we at BLB Industries believe that it is better to treat your prints rather than to having them ready from the machine.
Fused Granular Farbication (FGF) is an additive 3d printing method in which the 3d model is being printed layer by layer. FGF works by melting granular plastics and feeding the resulting mass at a constant speed through a nozzle onto a platform. By changing the nozzle, more or less plastic can be outputed at a time resulting in higher printing speeds or finer details.
For each layer printed, the printing platform is lowered, allowing for the next layer of the model to be added. When needed, a supporting structure can be printed to allow for overhang in the model. This method is most commonly used for the creation of prototypes and afterprocessing of the model, such as grinding, may be required to achieve the desired results.Read more about FGF (swedish)
