Filament does not extrude to tip of logo

Hi guys,


The bottom white line of the A does not turn out great.
On the sliced part the infill finishes at the blue line and has left a gap to the tip of the logo, is there any way to fix this?
Thanks

Assuming you have grouped the elements as an Assembly ('do so if you have not) then the order they are displayed affects this.

Move the white layer below the others.

Think:

  • Black
  • Blue
  • Grey
  • White

Top-down in this order, the white is then printed first and should take priority over the other layers that meet in the same spot.

I started out using white first, but on color change the printer would error out with clogged extruder (which was not the case), I will give that another shot…thanks

You are welcome.

Assuming that is a coaster, I designed and uploaded 189 coasters over several themes - that came up a lot!

What do you recommend for Coasters, does PLA+ take the heatr or need to use ASA ec?

I have ONLY created them with PLA and PLA+, the early ones were PLA.

A mug of hot coffee doesn’t affect them in the slightest.

Amazing thanks for quick reply, I haev lots of PLA+ and PLA META so will give that a shot.

Sounds like someone needs to simply print all of mine rather than spend time creating your own designs.

May I suggest the App Icon Collection, the Angry Emoji’s Collection or the Sickies Emoji’s Collection to name just a few?

It would be my honour for you to use up all that spare filament.

:smirk:

OT: Would you mind sharing what software and technique you use to create these coasters and flags? I would sketch something like this with Fusion, perhaps using a downloaded image as a template, but there are so many ways to do this.

I started out using Fusion 360 with the coaster and inserted the svg logo, I wanted a flush coaster but could not get it flush with Fusion, I am sure it can be done.
I decided to use Bambu Studio and used a cylinder to create the coaster and setting the logo at 0.4, my goal is to also have another small logo on the other side of the coaster.

This is the short version.

You need the artwork in a suitable format for your CAD software as this is where you would create the extrusions of the shapes that make up the design.

A vector editing package like Adobe Illustrator or Affinity Designer (there are loads of others) will let you create the artwork if it doesn’t exist or edit pre-existing artwork to get it ready.

The main idea is to get the artwork broken up into like colours. If the logo is red, green, and blue on a black background you need to separate the red into one SVG, the blue into a different SVG, and the green - you guessed it, into another SVG.

With those three SVGs, you would import them into your CAD software. Fusion 360, OpenSCAD, whatever you prefer.

You then extrude the shapes to the depth you require. Add a base circle (presuming your coaster is a cylinder) and extrude that. Move everything where it should be once printed as the positioning matters.

In my experience, the following values make for a good coaster.

  • Round base 100mm diameter
  • Square base 100mm wide and deep
  • Base thickness of 2mm (doesn’t sound like a lot, but it is)
  • Your artwork shapes should be 1mm thick
  • Print from the bottom up
  • 0.2mm layer height

Export all of those four objects as individual STLs.

Import all four STLs as one selection into BS, when prompted, say ‘yes’ when asked if you want them as one assembly.

If you wish to print the coaster upside down to take advantage of the textured or smooth plate surface - in BS, select the assembly, right-click, and mirror on the X-axis. Repeat for the Z-axis. (Ignore all of this step if you want the top surface printed up.

If you are printing the coasters upside down, change the top layers to 3 and the bottom layers to 5, this will make the eventual top surface have the best quality colours, particularly if you used white.

Select the Assembly from the Objects panel and expand the parts. Make the assembly the same colour as the base, then change all the colour parts to their respective parts. Tip; I always suffix the filename of the exported STLs (and vectors) with the colour name, it makes it easier when you get here and you have many to process.

Order the parts so the most important part is at the bottom and in decreasing priority moving upwards. When you preview the sliced results, your coaster should look great (if you printed it base up, look from underneath the plate).

ALWAYS preview each layer of the sliced design as you may have confused the order of the parts and colours you thought would print, simply do not appear.

If you look through my library, you will come across some that I have printed one colour below another colour to produce a tint or a shade (lighter or darker). This is achieved by creating a single 0.2mm layer shape and placing it below the top surface by one or two layers. It depends on the colour above and how translucent it is. Testing is a must.

Some of my coasters have design objects that are not 1mm deep and some that require a single colour to be broken up into more than one part so you can order the layers better.

Download some of my models to see what I mean.
