The 3D Printing Revolution

March 13, 2016

This is a very special post!  A guest post!

Barry Hand from Reify has been kind enough to collaborate on an article about 3D printing. Barry is an expert in the field of 3D printing and his company Reify has printed dozens of models for LS3P over the last few years.

In this post I will share how 3D printing has been a game changer for our practice: saving our clients money, saving us time and improving the overall quality of our presentations.  And Barry will answer the following questions:

  1. What are the the most common types of 3D printers?

  2. How much does 3D printing cost?

  3. How does the process of 3D printing work?

  4. Should you own a 3D printer or outsource?

 

How 3D Printing Became a Game Changer

Before I let Barry take the reins, I want to briefly describe how we use 3D printing at LS3P.

During my first 5 years at LS3P Charleston we rarely used physical models.  The rare occasion would be for presentation purposes such as an interview presentation or for a Board of Architectural Review meeting.   

Although model making was once a revered trait for an architect, the art and craft of model making has slowly dwindled.  In our office, it had become a dreaded task because it took a ton of time and nobody was particularly good at it.  In fact, the chore was usually handed down to the lowest ranking intern.  The last one in the door policy.

Cue the violins......

But then..........in 2013, we decided to try our hand at 3D printing.  The price for the technology had become much more reasonable and the quality was excellent.

We got hooked up with Barry's company Reify and began to outsource 3D printed models.  We were already digitally modeling our buildings in Revit, so there were only a few extra steps needed to get the Revit file ready to print.

We found the 3D printed models to be very effective and in 2014, LS3P purchased our own 3D printer.  We are now the proud owners of a MultiJet printer.  More on the different types of projects below.

We now print about half of our projects in house and outsource the rest to companies like Reify.

It has been a real game changer.

Rather than dreading the cumbersome handmade model, we now look forward to the opportunity to see our abstract digital creations come to life.  

 

Why should architects use 3D printed models?

  1. $$$ Cost

  2. Quality

  3. Time

I should point out that the model on the left was one of the best hand made models I could find in our office.  And it still doesn't approach the quality of the 3D printed model.

Also, it should be noted that the cost would be the cost for the client.  We don't pay our interns $85 per hour!  Haha.  I wish.

The timing is hard to compare.  Our outsourced models typically take 5-7 business days, but can be rushed at an up charge.  If we print in house we do have the availability to have something the next day.  

The key point is that once we send the digital model into the interweb, we don't have to do anything.  So the timing is irrelevant. 

At this point I am turning the article over to Barry Hand.  Take it away Barry!

The world of architectural model building is seeing a revolution of sorts.

Traditional methods of fabricating in-house models using balsa wood, foam, and foam core board can be very labor and material intensive.  A model constructed at a professional model shop can run in the 4-5 figures for a single model.

3D printing offers a digital solution that can save you time and money, and let you pursue revenue generating activities instead of long hours building a model.

3D printing (also known as additive manufacturing) creates models by putting down layers of material in patterns created by 3D computer aided design software (CAD). Each layer is a “slice” through the digital model, producing a very accurate representation of the original design.


What are the most common types of 3D printers?

  • MultiJet: binding powder with resin

  • SLA: liquid resin hardened by UV light

  • FDM: extruded plastic filament

  • Material jetting: multi material

MultiJet 3D Printer:  Architectural models are most often made using the Multi Jet process, also known as Color Jet Printing (CJP), because the printers use ink-jet like printer heads. CJP can print in color for little additional cost, produces models that look and feel like sandstone, and can reproduce fairly detailed surface features.  (This is the type Steve uses at LS3P)

SLA 3D Printer:  SLA yields the highest resolution, producing very fine detail and smooth surfaces. However, it can’t print in color, and is usually more expensive for larger models.

FDM 3D Printer:  FDM produces crude models which can be perfect for context or massing models. They are monochrome and have multiple color options.

Material Jetting Printer:  Material jetting is relatively new on the market, and can print in multiple materials and colors. However, this is an expensive process and should be used only when high detail or accuracy and color are required.

How much does 3D printing cost?

There are two main factors in calculating the cost of a 3D printed model:  

  1. file repair or conversion

  2. printing cost

Many CAD files can have hundreds of thousands, even millions, of “facets”. Facets are triangles created by software that represent every piece of the surface of a model, both inside and out.

Sometimes, these facets have errors that make the files un-printable. Talented designers with special software can repair and convert those files, which costs money.

The main printing cost is based on the volume of the material used to print the model.

For a 9” x 3” x 3” MultiJet model that required minimal repair and scaling, the final model cost would be approximately $800. On the other end of the spectrum, a 24” x 18” x 4” model with a lot of detail that has to be printed in multiple pieces and assembled would cost over $4000.

As stated earlier, color adds little to the printing cost. If you have texture files you can send them together with the CAD model. It is also possible to apply color to the model using graphical renderings, which adds to the file preparation time, and therefore the total cost of the model.

One important thing to note is that there is no added cost for complexity.  Therefore having a building with lots of ins and outs and organic shapes would not drive up the printing cost.  This is especially beneficial compared to hand made models where these types of complexities were extremely challenging to model and would translate into additional labor.

Get it printed!  The process of outsourcing your 3D printed model.

The idea of trying that first 3D printed model can be intimidating to many people.  Relax!  We have provided some simple check lists outlining the process.

Here is as helpful checklist for making sure your CAD model is as printer-friendly as possible:

  • Check your model to be sure that it is structurally intact. Detached roofs are the most common error.
  • Hide any features/layers you will not see: interior walls, staircases, cabinets and doors, etc.  Remember that you pay for material, so no need to print money inside of your model.
  • Consider the desired final model size and determine the scale of the model. Keep in mind any landscape details.
  • Separate each building into separate models. Don’t combine multiple context models into one file. This allows the printer to nest the models in the most efficient manner.
  • Remove any potentially delicate features that are not important in the final model. Sometimes lamp posts or railings are insignificant. But balcony rails may be critical to the visual perception and acceptance of the design.
  • Consider any coloring desired and have texture files or color renderings available.

Step-by-Step Process

  1. The first step is generally a phone call. You will discuss the project goals and timeline, as well as defining the CAD software you use. Most software can generate files that can be used or converted for printing.
  2. Upload your file through a portal, like www.reify.biz. This is a secure upload and can handle very large files.
  3. Getting a cost estimate is free and can typically be turned around in 1 business day or less. You should be sure to review the quote carefully to confirm the desired outcome. The final cost may be slightly higher or lower, but no more than 10% typically.
  4. Place your order! Include any last minute updates. Remember that large structural additions or subtractions will affect the final cost.
  5. The file is reviewed by a designer and converted to an STL (surface tessellation) file that is compatible with the printer. Some details may be too small to preserve after the walls and other thin elements are thickened for structural integrity.
  6. Printing is most efficient in batches, so models are printed simultaneously if possible. Printing can take 1 hour for every ¾” (19mm) of height.
  7. The model is cleaned up and additional bonding agent is applied, then allowed dry.
  8. Models ship very well. Your model can be shipped directly to you at whatever rate you choose.

 

Should you own a 3D printer or outsource?

Owning a 3D Printer

  • Many 3D printers are office friendly, while others require venting and special work space for post processing. 
  • The decision to purchase a printer must include whether there is space and power available for the printer and post processing, personnel to attend to the printing (typically one trained technician can handle a few machines), and dry storage for materials.  Many resellers offer maintenance packages, spare printing supplies and training.
  • Today there are ways to improve the fabrication of architectural models. The technology has improved a great deal in recent years and will continue to get better and less expensive. With a large enough volume, purchasing a printer might be right for you. There are many types of printers and they require some skill to operate.

Outsourcing 3D Printing

  • For some, outsourcing may be a wiser choice particularly if volume is small and personnel resources short. As you can see from the list above, the return on investment can be lengthy if you are not keeping a machine busy 24/7.
  • Outsourcing can also be a very cost effective solution.  The benefits include fast turnaround, highly detailed model features, and ability to change designs at low cost. Companies like Reify can help you find the best fit for your application and provide a turnkey service for your firm. 


Thanks to Barry from Reify!

Much love to Barry Hand from Reify.  I have been wanting to write a post on 3D printing for a while and Barry was kind enough to offer his expertise.  If you have any questions or are in need of 3D printing, give Barry a shout:

Steve's Final Wrap Up

Still not convinced?

The models pictured above are 3 iterations of the same project.  Over a couple of months we changed the design of the front facade and printed a model at each step.  

If we had somebody in our office model the same building 3 times by hand they would go nuts.  In fact, on one occasion our cleaning crew accidentally threw away a bin full of printed models.  It sucked, but at the end of the day it was pretty easy to have the models reprinted.

3D printing has saved our clients money and has saved our architects a ton of time.  Perhaps the best part is that the quality of the models is superb. 

If you have any other questions about 3D printing shoot me an email or reach out to Barry.  And remember.....sharing is caring!

Cheers!

Good morning from Elliott Street!  This handsome devil is a newish building that has some great brick details.  How about some brick terminology?  At the heads of the windows and doors at the 2nd and 3rd floor you will see what is called a ‘Jack Arch’ or some call it a ‘Flat Arch.’. Rather than a typical round arch the jack arch angles the bricks to create a keystone effect in which it can actually support the wall above.  Look up at the top of the building and you will see banding.  This banding is created by gradually stepping out the brick like a game of jenga.  This stepping of the brick is called corbelling or one may say brick corbels.  One last 🧱 term, this brownish colored brick is referred to as Savannah Grey and is very common in the Low-country.  And there you have it folks.  #themoreyouknow🌈

Good morning from South of Broad!  Another photo where I can't remember the street.  I believe it was either Church or State?  #punny  This #singlehouseoftheday has got something that is very rare in Charleston.......a front yard!  One of the biggest differences between urban design and suburban design is that in the city, the buildings are right up on the street, whereas in the burbs the buildings are set back from the street.  This is certainly the case in Charleston.  It is one of the things that makes are streets so beautiful.  The buildings line up like soldiers (soldier buildings we call um) and form an urban wall that makes the street feel like a room.  Now, occasionally there is a home that bucks the system and has a front yard like this guy.  And good for them! Yards are awesome.  When I am on my urban safaris I am often enamored by the landscaping and hardscaping of these little yards and driveways.  Buildings are cool...but so are gardens and even driveways if done well.  In fact, when I give folks tours South of Broad I find them most amazed with the driveways and mini-gardens.  #gardensarecool

Good morning from King Street!  You know that it is @sewechs weekend when you see a fella carving a wood duck in front of the @audubonsociety gallery.  Head over to Marion Square this weekend to see all the cool wildlife and neat things.  And if you are like us 8 years ago, walk by @mdumasandsons and accidentally buy one of the puppies in the window from @charlestonanimalsociety  Best accident that ever happened.  Cheers and have a great weekend !!!! #dailydoseofcharleston #sewe

Good morning from State and Chalmers!  This building is one of my favs.  It does a lot of things right but it it is also imperfect and quirky.  The proportion of the facade is 💯 Tall and skinny just looks good.  The aspect ratio of the facade is 2 to 1, which would be the height to width.  It has great balance, aka symmetry.  Each floor has a different window pattern which adds interest.  The stucco has that patina look that we all go gaga over.  Some of the quirks:  the 2nd floor window looks like it may have been a balcony at some point.  The front door seems too small and should be taller.  The proportion of the top window is wonky.  The banding at the 3rd floor line almost seems industrial.  But it still works.  It has character.  What do folks think?  #dailydoseofcharleston

Good morning from Broad Street!  This little guy is known as ‘Fast and French.’. The longer and much harder to pronounce name is Gaulart and Maticlet French Cafe.  I hadn’t stopped to look at this building before until last night when  I was down here with my @cpad12bull students.  About 20 minutes later we got caught in a crazy rain storm 😜 🌧..........but back to the building.  I am not a master of architectural styles but I might call this Greek Revival.  The pilasters on the corners and pediment look at the gable recalls a Greek Temple.  Thoughts?  One thing I can decipher is the form of the Charleston Single House.  If you look to the left you see a sliver of the  building that looks like it could have been a piazza (side porch). Maybe it was a piazza that was filled in at some point?  Because of that I am going to call it the #singlehouseoftheday

Good morning from Marion Square and the Hotel Bennett!  This brand new hotel is all everyone is talking about.  My favorite part of the exterior is this little bit here.  I love the large windows and especially love that they have this exterior seating area.  It is a great way to engage with Marion Square.  It reminds me of the great piazzas in Italy where the surrounding sidewalk cafes spill out into the space.  The roof deck at the top of the photo is another great way to connect.  I have not been inside yet.  Have you? #dailydoseofcharleston

Good morning from King Street!  These are a couple pix from yesterday’s Second Sunday on King.  For those not familiar with Second Sunday’s, from 1-5pm, the city closes King Street from cars leaving it as a pedestrian paradise.  If someone were to ask me about Charleston’s best public space, I would say King Street.  A good urban street should feel like an outdoor room and that is definitely the case with King Street.  Question: should they close King Street off from cars more than just one Sunday per month?  Twice a month?  Four times?  Every day?  #dailydoseofcharleston

Good morning from Archdale Street!  This #singlehouseoftheday is a big boy!  One of the tallest Charleston Single Houses you will find at 4 1/2 stories.  In Charleston we refer to a habitable attic as a 1/2 story.  Although it is hard to see from this angle there is a hip roof up there and we can guess it is habitable from the dormer window.  For scale purposes  look at the 2-story single house to the right.  This exhibits the versatility of the single house in that it can be scaled up or down.  This house has something that is now considered taboo.....can you guess?.........The piazza (side porch) has been filled in on floors 2 and 3.  Nowadays, the Board of Architectural Review (BAR) will not let folks infill their piazzas.  Although this infill looks pretty good, this sort of thing runs contrary to the preservation mantra we embrace in the Holy City.  The piazza is the most defining feature of the Single House therefore it is critical that we save these gems. #dailydoseofcharleston

Good morning from Tradd Street!  Yesterday was a white house with a red door. Today is a white house with a pink door.  Or is it salmon?  Or Coral?  Whatever it is, it works.  You may be thinking, is this a Charleston Single House?  It does have a Piazza (side porch). But a single house is called a single house because it is a single room wide.  I have not been in this house but it is clearly more than a single room wide.  Likely 2.  Is it a double house?  Double houses typically are 2 rooms wide plus a hall that runs down the middle.  A double house would be 5 windows wide on the facade.  So not a double house.  So what is it?  #dailydoseofcharleston
