Alfred" chair (true to scale)

*Genuine German furniture measured and digitized by hand. *

The "Alfred" chair with its curved milling work and the turning on the front legs reflects the typical design of period furniture from the 70s. A wide chamfer that does not start at the ends of the legs makes the legs appear less angular and rounds off the whole thing harmoniously. To top it all off, the acorns on the top of the chair back complete the furniture to create a magnificent specimen.

A piece of furniture with history is now ready for your 3D printer. They can embellish their model world with different scales.

Scale

All my furniture models are true to scale. With the 2 preconfigured scales you can make your scale diorama.

If you already have your own scale, you can use the 1:1 scale file to reduce it to your individual scale.

History of the original

My grandfather Alfred bought the chair in the chair in the 70s, as old Super 8 recordings testify. That's how it got its name. He owned the chair until the 2000s. After my grandfather bought a new one for his living room in May 2004, we got the chair, which was initially in the kitchen but was later moved to the conservatory.

This model is part of my collection "The Struckmann file"

Instructions for loosening the support structure

if you have a dual extruder, use water-soluble support structure. Because loosening conventional support structure is tricky. Otherwise, here is a procedure that I use:

Removing the fixed support structure on the seating furniture models:

Removing the support structure requires a little patience and dexterity. Depending on the size of the scale, the support must be removed piece by piece.

First remove the object from the print bed with a sharp spatula. Then remove the brim from below. Do not hold the model by the chair legs but by the edge of the seat or the support structure. These could break off at small scales. The brim must be completely removed until the chair legs are no longer connected to the support structure.

Important Hold the chair by the seat

Carefully cut or pull off the supports that have formed on the sides above the chair rungs in the direction of the layer if possible.

Then use a small side cutter to make individual vertical incisions in the tree support structure from below and then carefully remove the support structure layer by layer.

Once you have almost reached the bottom of the seat, lever off the rest with a narrow spatula and make sure that the support structure does not push the chair legs to the side, as something could break off just before the finish.

Reworking

Remove the pimples on the lower edge of the chair back with a half-round key file or a pointed carving knife. Always work with the knife away from the body due to the risk of injury.
