Design based on 3DVerkstan Face Shield by Erik Cederberg
https://3dverkstan.se/protective-visor/https://www.youmagine.com/designs/protective-visor-by-3dverkstan

Remixed by Supercell

Key design additions:

  • Easier to print pins with more secure visor fit
  • Choice of options for different design requirements, such as extended visor distance from face, improved coverage of top cover or faster printing.
  • Cleaner overall design
  • STEP files available for any personal adjustments

Design Options:

  • Standard version similar to 3DVerkstan
  • Open version similar to 3DVerkstan but with open top
  • Cover version with widened top cover
  • Extended Cover version with extended distance from face and widened top cover
  • Extended Open version similar to extended cover version but with open top

Stacked Options:
One version contains adhesion supports to help provide adhesion between each band. This may give enough adhesion to prevent bands from warping, but I've added a version with no supports if needed.

Hole Spacing: Currently I have only made Europe 888 4 ring hole punch spacing and North America 6 hole 3 ring hole punch spacing.

Notes: For further information on spacing, templates or guides on assembly, please refer to the original 3DVerkstan design

  • First G-Code Stacked Print Test

    Supercell04/13/2020 at 00:30 0 comments

    First test of printing using a g-code print without any manual intervention in changing temperature and speed. Separation of the bands was fairly easy without the need excessive force. Delamination layer parameters were entered into the start and end of the layer using PrusaSlicer.  Parameters were mainly to turn on fan, lower the temperature of nozzle and lower the printing speed. Once the layer was completed, the printer resumed normal operation.

    Printed using a 0.8mm nozzle, 0.3mm layer height, 30-40mm/s speed, 1mm line width at 240C nozzle temperature for PETG. Parts are separated by a 0.3mm Z gap
    Slicing and delamination parameters done in PrusaSlicer
    Delamination layer parameters:
    Start layer -
    M106 S255   ;Turn on fan at max speed
    M104 S210    ;Hotend set to 210C
    M220 S60    ;Print speed set to 60%

    End layer -
    M106 S100    ;Set fan to normal speed
    M104 S240   ;Hotend set to 240C
    M220 S100   ;Print speed set to 100%

  • Stacked Print Success

    This might not be a new idea but I remembered that whilst I was printing PETG at 240C, I had horrible delamination problems between layers and had to turn up to 250C to get reliable prints. So considering that we wanted to stack prints, I wondered why not use this to our advantage.

    Here's a depiction of what I'm thinking:

    This method really depends on how well you are able to control the hot end temperature, what temperature the material delaminates at and what material is used. 

    I've experimented with PETG and it shows promising results that we can reliably get stacked prints that can be split apart easily by hand.

    Left print shows the bottom of visor 2 and the one next to it is the top of visor 1. The surface finish is quite good with minimal drooping of layers as the layer was fully supported with no separation distance between each band. This is only one test print but it could be possible to repeatably create stack prints that are easy to remove using this method. This method does vary from printer to printer and material to material so do be aware. If the temperature difference between normal printing temperature and delamination temperature is too great, you may need to make some compromises on certain layers so that the hotend can reach the target temperature quickly. 

    Currently, I haven’t yet seen a slicer implement a delamination layer operation but hopefully it will be added soon. There are workarounds with slicers like Cura but the effect may not function as well, due to how the nozzle takes time to change temperature.
