Batman bust

Our filaments already look great when printed, but we get a lot of questions about post-processing. Not only materials where this is kind of necessary (like bronzeFill or copperFill), but also other materials are often the subject of some serious post-printing work to make the printed object truly unique. For this post, our technical development manager (and part of the Team colorFabb from the very beginning) Gijs Houdijk takes you by the hand to show how he post-processed this awesome Batman bust, designed by David Östman.

Design at MyMiniFactory

To begin with, we used our very own PLA Semi-Matte White as the basis for this print, using the standard PLA settings on the Makerbot Replicator 2. For this print we used a 0.15mm layerheight, lower layerheights equals less sanding to get smooth areas.

Well, this Batman bust already looks pretty great, but Gotham’s Caped Crusader can even look better! Below are the post-processing steps that Gijs took.

1. Primer & Sanding

I usually start with a couple of layers of primer. After this I’ll start with sanding, using 220 grit. Then add another layer of primer and continue with sanding. My goal is to smooth out af much as possible the exposed area’s, without loosing detail in the print. The smoother the exposed area’s are, the better they will look after Step 3 ‘Wheathering’.

2. Silver base coat

I used Vallejo Acrylic Metal Color for the base silver metal coat. Instead of using an airbrush I used regular brush to apply paint to the model. It’s a very thin paint which coats really really well. It also dries super fast and is very easy to get an even coat.

3. Weathering the model

After the base coat I apply black spray paint to the model and immediately remove as much as I can with a soft cloth. Don’t let the pain dry, you want to wipe it off while it’s still wet. You can do this one side of the model at the time. The smooth exposed area’s will be wiped clean, revealing the metal looking surface. All the nooks anc crannies will stay dark because of the black spray paint, creating a nice contrast with the metal looking surfaces.

4. Glue both parts together

I used LOCTITE® 3DP INSTANT BONDER. Great feature of this glue is that it hardly turns white after it’s set, which some CA glues do tend to have. Loctite is available in the colorFabb webshop.


PLA Semi-Matte White is a great material for architects and model makers looking for a different aesthetic. Our semi-matte PLA filament eliminates the glossy appearance seen on most PLA 3D prints. The highlights on the surface will be less visible, resulting in an overall cleaner and much higher quality look. This makes it also a good choice to use as a base for prints that need to be post-processed.

As with its black sibling PLA Semi-Matte White contains no fibers and prints at regular PLA temperatures and settings. The material is as reliable and easy to work with as any other PLA type material.

Back in June 2016 we announced steelFill to the world. In September we launched steelFill officially. Today we have printed an aptly themed object with steelFill : the Man of Steel logo.


Modelled by Filippo Panza, this design is based on the current Superman series and quite appropiate for our steelFill.

With steelFill we are added a fourth metal based filament to our portfolio after succesfully releasing bronzeFill in 2014, copperFill later that year and brassFill in early 2015. As with these other filaments, the key is post-processing and you can use similar techniques as with our other special metal based filaments.

You can find the full tutorial on how to print with steelFill here.

This part was printed on the Makerbot Replicator 2 with a 0.2mm layer height at 210 degrees C. steelFill is an abrassive filament and not kind to the standard brass nozzles.

For the nozzle we chose the Olsson Ruby nozzle 1.75mm version. the ruby nozzle retains the excellent heat conducting properties of brass, while being extremely resistant to wear. This means that you can print your standard materials as usual, but also very abrasive materials such as steelFill but also our XT-CF20.

The Olsson Ruby is a high-tech nozzle with a carefully designed ruby tip, which makes it have unique properties. The ruby nozzle is designed by Anders Olsson, inventor of the popular Olsson Block that is also part of the Ultimaker 2+ 3D Printers.

This nozzle was generously supplied to us by 3DVerkstan, our distributor and partner in the Nordic regiona and manufacturer of the Olsson Ruby Nozzle. For more information about the nozzle, contact 3DVerkstan:

There will be a separate blog about post-processing this piece later on. You can find more prints made with steelFill, which have been post-processed, here:

Yeah, we like our superheroes…

steelFill is available in our webshop and through our network of distributors and resellers worldwide.
