This will likely not become a video but I have just achieved a great result doing this so I thought it best to tell the world before someone else demonstrates it and it becomes common knowledge. It is totally possible to have multiple colours in a resin 3D Print. The 3D printer I have used to do this is an LD-002R Resin 3D Printer. All the resin I use is quality and has been made from Creality.
The Process is as follows
- Start a resin print like normal.
- Pause it at the layer you want to change colour
- Remove the resin in the bath.
- Replace the resin with another colour.
- Adjust the printer settings for this new resin.
- Resume the Print.
Do this and you can have multiple layers of different colours to your resin prints. Below is a simple example of this process that I present to you. This is a digital scan of a relief found in Thorvaldsens Museum in Copenhagen Denmark and is of Priam pleading to Achillies for his Son Hector. It is only an inch and a half long wide and thus some of the finer face detail is lost because of it. Some finer tuning of the white resin and printing it larger would rectify this.
It is common knowledge in FDM printing that you can multiple colours in multiple layers by pausing the print and swapping out the filament. In fact, it is so commonplace that any slicing software worth its salt has the option to pause at a certain height. SLA and DLP printing software has a ways to go in this regard and no software (as of 20-05-2021) I have found will allow me to pause a print at a certain height. This leaves me with no choice but to stop the print manually at the height that I want to have the colours change to get this effect.
Another avenue I would like to pursue in this regard is combining resins that have different properties together. My concern for this is that the different resins with different properties will not adhere as well.
