Step into the fantasy world of  Guido Mandorf: a mini world full of scaled models.

Since it’s ‘prime gray month’ at i.materialise, Guido is the perfect designer to feature on the blog. For his models he 3D prints in this material and paints the models afterwards.

Can you tell us a bit more about yourself?
«I live with my family in Düsseldorf. After my studies- Mathematics and Informatics I started working  for the university of applied science in Düsseldorf. Next to that I’m the head of an education center in Düsseldorf.»

When did you start being interested in scaled models?
«I started 3d modelling about 2 years ago. Before that I made scratchbuilt models and models made of brass.»
«I get the inspiration for my models from historic cars in Düsseldorf and around. But also from books and old pictures. »
«The community of model tram enthusiasts is not very large. Here in Germany many people know each other. Via Facebook I met people from other countries, who have the same interests.»

When did you start to 3D print your collection?

«I started 2 years ago. I read about the 3d printing technology on the internet and thought that this might be a great idea to realize my desired models.»

Did it change your view on designing?
Oh yes, completely. Usually I built my models as scratchbuilding from others but now I construct everything for myself. I only buy bogies, axles, motors and bow collectors.»

Where can we find more of your work?
You can find more of my models on my webpage www.tramspotters.de (only in German) or on Facebook: www.facebook.com/tramspotters.de »

How do you see your future?
«I think 3d printing is great for all model builders. I hope the materials will get smoother on the surface and that it will be possible to print smaller parts that are thinner than 1 mm. »

Green means ‘go’.

No worries if the winter is coming..

  • Excellent work, from design to painting. Would like to have seen something to get a sense of scale.

    Thanks, Glenn.
    All my models are scaled in 1:87 (H0). The model on the first pic has a length of about 13cm.

    Hi Guido, I have been admiring your work on the Tramspotters” Facebook page. I especially love your OEG cars. I had been thinking of trying to make the big OEG cars I saw in the Hannover Tram Museum last July. However I am originally from Blackpool (although I live in Northern Ireland now) so I”m focussing on Blackpool trams.
    I am very much a newcomer to this field and I”m not nearly as proficient as you in creating models. I have been experimenting with CAD and using Shapeways but they are very expensive. I use their frosted ultra detail because they will allow thicknesses down to 0.3mm and for very old trams that is needed for the handrails. Have you any advice for me?

  • Guido Mandorf

    Hi Stephen,
    thanks for your comment.
    I think PG is the best material for modelling, because it has smooth surfaces and it´s strong. It´s pity that you need at least 1mm as thickness for PG . I make handrails with thin wire made of brass (0,3 or 0,5mm). That´s much better.

  • Hello Guido
    I noticed you are printing your models in the “normal” orientation. I have had some success in getting a smoother surface for models with a curved roof, by printing them on their side. (I also use Prime Grey). However, this also means printing in two sections to avoid getting supports on the visible, outside surfaces. I have just done a new version of my diesel locomotive in two sections, and the surface quality is much better on the curved surfaces.
    I have only been doing 3D modelling for about 8 months, so I am still learning.

    Hi Richard,

    thanks for your comment. Do you have some pics where I can see the difference in the printing orientation?

    Thanks
    Guido
