The Problem: When Improvements get in the Way of Art
One of my first lessons from the Wivenhoe Print works was using AKUA intaglio ink for relief printing. This ink helps to get better detail in the final print as it does not get clogged in the plate. This created a new problem of highlighting the layer lines of the 3d print process which is not good for the final print.
The Solution: What is 3D Print 'Ironing'?
I decided that I needed to experiment with the ironing setting in Bambu studio to create a smooth final surface. Ironing is a setting where the printer goes over the surface with a heated nozzle and reduced flow rate to smooth the surface.
The Experiment: Finding the Sweet Spot
I could do lots of sanding to try and remove the layer lines but decided to experiment with the ironing settings to find the optimum for the grey PLA that I use for my print plates.
I designed a test plate with the types of detail I like to use. I printed a grid of these tiles varying the nozzle speed and flow rate to establish the best combination of smoothness and detail retention. This first grid highlighted some settings that were getting good results so I refined around those and did a second iteration.
Finding this 'sweet spot' was incredibly satisfying—it feels like I am mastering this part of my process so it can truly serve the art, rather than dictate it.
The Result: Ready for the Next Piece
This technical win means the final prints you see in the shop will have the crisp, professional finish that make the prints pop
