For the last couple of month's I have been thinking about getting a 3D printer, I did not want to spend too much money and the 3D print playing field is a minefield.

I plumped for a second hand Dremel 3D20 which was the first Dremel offering in the 3D print World back in about 2014. The machine is based upon a Flash Forger Dreamer but has Dremel branded software and only a single extruder and non heated bed.

I bought the machine on Ebay, it had been in a school and only had 2 hours print time on it (there is built in run time clock),

The machine printed a supplied sample piece on the first time of asking, I printed a further two sample pieces and then went with my own designs.

The two parts on the left of the photo are mounts for a pulse jet engine on a control line speed model, these are only for mock up purposes as the pulse jet heat will melt the PLA plastic.

The item that looks like a clip is in fact for holding the wings on a small chuck glider of the style of North Pacific types. Basically the two 1/16" balsa wings push in either side and the clip also has dihedral designed in, then the assembly pushes onto the 1/8" balsa fuselage, worked great, done 10 of these for chuck gliders at a children's party we held last weekend. The wall thickness of the clip is 0.7mm and to be honest the finish is fantastic, it just looks like an injection moulding.

The final item is a control horn to pick up on an aileron torque rod in a new Q40 pylon race model that I am building, the two holes for the clevis to pick up on are 1.6mm diameter, so that gives you an idea of scale.

I am blown away with the quality of the parts produced so far, they exceed my expectations by some margin and that is not easy !!

Regards

Barrie
