Hello everybody,

the parcel from Holland got there faster than I thought, and of course it was opened immediately. And already the first glance through the two bags onto the Combos looked very promising and pleasantly surprised me.



And even after unpacking I was very impressed by the sight,



whereupon I took a closer look, here first a Combo-R,



as well as here a Pair (R/L) lying next to each other,



and here in the installation position in the Truck.



Now all 16 Combos that are required for the Crawler have been completed, which was made possible by the spontaneous helpfulness of my ARC friend Pascal (bubble) went faster than I could have imagined.



Nevertheless, I then took a closer look, and here is the comparison with the last printed Combo Pair (XSFDP) which was printed in the best print orientation, the contours of which unfortunately cannot be recognized better, due to SW's well-known Print look.



Therefore, for a better comparison, here is a larger macro shot in the installation position,



and here still with a look at my Scratch prototype, which looks a bit more filigree in some details like the stiffening struts because I made them from Styrene (0,15 mm), which corresponds to the paper thickness used in the Paper Kit (MicroArtwork), but what cannot be realized in 3D printing due to the minimal wall thicknesses > 0,3 mm, as requested by SW.

On this point, Paper modeling is plain and simple superior to 3D printing, what my friend Joe (crackerjazz) honestly admitted right at the beginning of our modeling efforts.



Before I go into a few more details (i. a. painting) of the Resin Combos and the quality of the last SW prints, I would like to underline in a first résumé that I can imagine the Crawler with these Resin combos very well and that I presumably can save the printing of further SW-Combo-Pairs by SW.

Thanks Marcell for your compliments and stay tuned, it's worth it, the journey continues ...

Hello everybody,

today in a follow-up I would like to take another look at the Priming of the Resin combos, because on closer inspection I noticed certain differences in quality.

In the unprimed state immediately after printing, the details of the combos were still clearly pronounced, as one can see here.


Source: arcforums.com (bubble)

Then my friend Pascal (bubble) allegedly gave them a thin layer of a gray primer with MoTip Primer (04054) from a spray can.

The following comparison makes it easy to see the different layer thickness of the primer. While the details come out relatively well with the left combo, with the right combo they are quite heavily covered by the primer, which doesn't look that great, but is still quite acceptable.



I had already observed similar results myself when priming/painting models from the spray can and have since been rather skeptical about this method of applying paint, as the amount of paint cannot be dosed evenly and finely enough and the risk of leveling details is relatively high.

On the other hand, these problems can be largely avoided when using good Airbrush equipment, in which the paint application can be dosed much more finely.



Nonetheless, I can use the Resin combos for my Crawler with a clear conscience, as I can choose in which places on the trucks I install the 'less good' combos, especially since they in the installed state can hardly be seen between the trucks anyway and then also only the upper sides of the combos with the Propel motors.

Dear friends,

in weeks of painful grief I want to try to slowly come to my senses and bring myself to continue working on my project ...

For this purpose I took the last printed Gearbox-Pair (XSFDP) from Shapeways and examined it once again more closely, because in retrospect I noticed some things that are not entirely plausible to me and do not really want to please.

In order to minimize the wax residues remaining despite Shapeways' cleaning after printing, we had let print this pair in the best possible print orientation (standing upright), which we had been previously recognized,


Source: ARC Forums (crackerjazz)

which has the following support wax arrangement.


Source: ARC Forums (crackerjazz)


Source: ARC Forums (crackerjazz)

At first glance, the Combos (XSFDP) look clean on the outside, only there are wax residues in the inner cavities of the gear case and on the underside of the motor, which, however, are not so important for the later priming/painting, because one can hardly see these areas in the installed state anyway.

However, clearly visible longitudinal grooves on the surfaces are noticeable, which I cannot explain to myself due to the selected print orientation, which is why I asked Shapeways for a statement.
These grooves are clearly felt and have after all a distance/width of approx. 0,4 mm.



These two SW Combos I have now tried to clean so that they can then be primed and compared with the Resin combos, which I'll use for the crawler.

This time the cleaning was not done in the dental laboratory but by using my small Ultrasonic cleaning device,



based on the conditions proposed by BANDELIN at that time by using TICKOPUR R 60.


Source: bandelin.com

Since my US bath has no heating, I filled the trough with 50°C hot water and added 20% TICKOPUR.

But since the Combos swam up and didn't want to sink,



I've held them down with tweezers and cleaned them approx. 2 h by turning over several times at intervals of 10 minutes.



Then they were rinsed in water, dipped briefly in 2-Propanol and dried under the hair dryer.



As one can see, the cleaning time of 2 h is not enough to completely remove the wax residues out of the inner cavities, but which is no longer important to me.





Both on the underside of the engine, as can be seen here,



as well as inside the case there are still considerable wax residues.



So I want to leave it at that for now and will now prime both combos in this state and also my scratched prototype in order to be able to compare them with the primed Resin combos.

Hello everybody,

in response to my complaint about the grooves, Shapeways has sent the following statement:

Hey Manfred,

Let's start off by saying sorry! We work hard to make sure you are 100% satisfied with your purchase. Unfortunately sometimes we mess up.
To make sure you are completely satisfied we just placed a new order for you at no charge.

Your new order will ship by: 2021-10-25

Well then, let's wait and see the new MotorGearboxCombo-Pair in Smoothest Fine Detail Plastic (XSFDP), I'm curious.

They're a class act to be sure! And just to sure there's no mistake, here's Merriam-Webster's definition:
Definition of class act



: an example of outstanding quality or prestige
