3D printing workshop at the IFIB

If you need a part for a laboratory machine or if you want to print a model of a molecule that you are working with, you can do so with us. Printing will take approximately 1h per cm3, varying significantly with the level of detail and quality of the desired model.

Preparation

First you need a 3D object. This will usually come in the form of an STL file encoding a 3D object. You can download many pre-made models from repositories or you can create your own using any 3D design software. Once you have your STL file, you need to load it into Cura which will turn it into printer instructions. With this software you will be able to see your 3D object, select the printing options (speed, thickness, filling, etc.) and save the printing procedure in Gcode to an SD card. With your object in Gcode on the SD card, you are ready to go to the Ultimaker2 3D printer.

Printing

This is what will happen next. The printer will first warm the extruder and the bed. Once both have reached the designated temperature, the printer will extrude a little molten filament to prime the nozzle. Then the printer will start to print a skirt (a small perimeter around the base of the object) to ensure regular flow. Use this opportunity to check the quality of the printing (homogeneity, attachment to the bed). The print will then proceed layer by layer as written down in the Gcode. When the print is finished, the bed will be lowered automatically.

Finishing

Costs

IFIB lab and faculty members print for free with standard PLA filament up to 1 roll per year. If you need to print more or if you require more expensive specialty filaments, please purchase the material yourself. We are currently getting our filaments from 3DPrima (Sweden) because of a combination of competitive prices and variety of material.
