Our project involved designing and printing multiple 3D printed parts. Since we wanted to build a spectrometer, designing it ourselves gave us a lot of flexibility on how we could use it.

Here we attach the protocol we used and a PDF of the same to design the ‘Cuvette holder’ and ‘Grating Lens Mount’.

1 Introduction

3D printing is a revolutionary and convenient technology for the production of complex structures that are difficult to construct by hand. The reliability of the process has increased rapidly in the past, to the extent, that it is now used as an industrial production tool too. We decided to leverage the advantages of 3D printing for the construction of our spectrometer too. The workflow is detailed in the sections that follow.

2 Workflow

2.1 Design

This involves creating a 3D CAD(Computer-Aided Design) model. Various software is available for this- AutoCAD, Solidworks, TinkerCAD, etc. We did our designing in Solidworks. The spectrometer consists of the following parts:-

Cuvette holder → It’s used for holding the cuvette containing the sample.

Grating lens mount→ It’s used as a mount for the grating and the lens.

• Slit mount→

​​

  • Smartphone mount

Once the design is ready, it is saved in a format determined by the software used. Solidworks saves the file in ‘SLDPRT’(solid part) format. An ‘STL’ file can be exported for slicing later.

2.2 Slicing

Slicing involves the conversion of the ‘stl’ file into a ‘gcode’, a standard language for most 3D printers. ‘FlashPrint’ and ‘Ultimaker Cura’ are some common software used for slicing. Important precautions during slicing include:-

• The model orientation should be kept such that a minimum amount of support is printed.

• The model should lie flat on the base.

The slicing parameters we used are as follows:-

Infill Density: It’s the density of the filament to be used for printing. For larger models, one can decrease the infill density to save filament. In general, an infill density of 15% is good enough.

Support Infill Density: It is one of the most important parameters. Some- times the model can be complicated and delicate and need support. In these cases, it can become difficult to remove the printed support. So we may decrease the support infill density so that removal of support after the print is easier.

2.3 Printing

This is the final part of our workflow. Once the ‘gcode’ has been obtained, it can be fed into a 3D printer either using an SD card, via a direct connection to a computer, or over a network.

2.4 Pitfalls we faced

  • Sometimes, the base may get detached from the printing bed. It can happen due to the large size of a model, bad quality of the bed, or low temperature of the bed.
  • Sometimes the filament gets brittle. So while printing, the filament stops coming out from the extruder. In this case, we have to clean the nozzle and reload the filament.
  • Sometimes the filament may get stuck in the spool and break. In that case, we have to reload the filament and restart the print.
