How We 3D Print A Tower’s Dome

When was the last time you went for a property search, especially new property launches?

Architecture Model

We often scout around the models, checking if the facilities are built as per promised. Checking the traffic around the vicinity, direction and coordinates for the best Feng Shui. These property models are typically handmade from card boards to wood, or even acrylic as these are precise manufacturing methods, however, they are taking at least 1 – 2 months for the production and may cost up to hundred thousands for a simple model with LED lightning etc.

 

With the understanding that models need to be explicit, one client approached and requested for us to test print the highest part of a tower – a Dome:

File Source: Client
Technology: Polyjet
Printer:  Objet Design Series
Materials: VeroWhite Plus, VeroClear, Fullcure 835
Build Time: 7 hours and 7 minutes

Screenshots prior printing:

Outcome:

Implications:

  • We printed this model with Polyjet technology at 30 microns or 0.03mm for the precision. Noticed that it has some windows in between the dome itself?
  • It was in glossy finish (hence you would notice the surface is shiny). While the image quality may not be good or it appears to be, rough finishing (blame our phones), it actually has a pretty smooth surface and can be enhanced if needed.
  • Traditional model making methods may require assembly and take major time on refining the minor details on the dome. This was printed in mere 7 hours with no touch-up.
  • The best part is the material cost is way cheaper than traditional method, contact us to understand more about the costs and ROI.

Seeing AM as a different way to tackle traditional model making not only allows a better ROI, it also allows a better flexibility in terms of man-power. Best part is, you get better quality product as well!

3D Printed Heart Model - Full 2

We Printed An Actual Human Heart

It’s real. We 3D printed a heart.

Hold your horses on questions and listen to us for now.

The ultimate goal in medical field  is to 3D print a fully functional heart however, with many technical considerations such as tissue condition, implantation, sustainability and etc, 3D printing technology is still lacking in these areas albeit advancing at a steady pace.

This 3D printed heart in particular belongs to a patient. Our client intended to study his/her heart to understand how the surgery can be done, as well as using the heart model for explanation. As we’ve mentioned on our Facebook and LinkedIn, this is one of the best study materials you can have prior a surgery.

Here is the file source & technology we used:

File Source: Rapid Model Development Sdn Bhd
Technology: Polyjet
Printer:  Objet Design Series – Connex 3
Materials: VeroWhite, VeroCyan, VeroMagenta
Build Time: 11 hours and 52 minutes

Screenshots prior printing:

Outcome:

Implications:

  • We used Polyjet (or Connex 3 in particular) in this case as it offers multi-material and multi-color capabilities. This heart model in particular, requires a lot of precision to print out blood arteries as well as rubber-like texture.
  • Some may ask, why not print this in a go? Yes we can, not an issue at all. However to allow doctors and patient to understand the heart structure in a detailed manner, we made the model in assembly format.

We hope that this model will aid surgeons in their surgery understanding, as well as helping patient to understand better of their own heart condition.

3D Printed Motorcross Helmet - Front

Motorcross Helmet in Action

This week we printed something different, something that racer boy would yearn for – Motorcross Helmet. The best part is right after the model was printed, we had the opportunity to showcase this during Innovating Malaysia Conference 2014.

Here is how we did the printing, and some underlying reasons of material & technology selection:

File Source: Rapid Model Development Sdn Bhd
Technology: FDM
Printer:  Fortus 380mc, uPrintSE
Materials: PC-ABS (Black), ABS (Red)
Production Time:

Fortus 400mcuPrintSE
Build Time86 hours 24 minutes 7 hours 44 minutes
Assembly Time30 minutes
Support Removal Time16 hours6 hours

Screenshots prior printing:

Outcome:

Implications:

  • Traditionally, the production material for helmet is polycarbonate (PC) for best endurance and heat resistance. However, as we wanted the helmet in black and red which is not in the range of our PC material, we opted for PC-ABS instead.
  • PC-ABS combines the best of both materials (PC & ABS) – the superior strength and heat resistance of PC and the flexibility of ABS.
  • For drop testing and pressure testing etc, this prototype will serve as a good gauge for improvements as compared with existing product.
  • Noticed how the black helmet base was printed in a go but we had to print the decor separately? This is due to FDM does not support multi-material modelling as that is under Polyjet’s feature.
