Layered Labs 3D Printer Design Challenge

Medium

Layered Labs challenges you to help design a new 3D printer!

3D Printers could very well change the World. They've already helped in the design process of countless Engineers and Designers. Having your CAD model in your hand rather than an abstract model is vitally important, and 3D Printers make the process easier. For consumers, a 3D printer means 'download-and-print' is a possibility instead of 'going-out-and-shopping'. For small businesses and workshops, it means small production runs of small new or low-demand products are doable and completely profitable.

For the first time, the GrabCAD Community has the opportunity to design a 3D Printer. This design challenge is open ended to allow for substantial creative freedom. Your work will ultimately help set the design language for an entire brand of products. Good entries will be designs that are easy to manufacture, elegant in form, and that satisfy as many of the design requirements as possible.

Aesthetically, the look captured needs to be unique and help define the brand. It needs to be compelling, and able to showcase a really cool, new technology effectively, without being brash or overstated. It needs to do this while also being approachable to the average consumer - all of the existing 3D printing designs we have seen from any company are inadequate in this regard. We recommend looking at Leica cameras and Apple products as good examples of appealing industrial design, but do come up with your own original concepts.

Competitors are encouraged to submit sketches at first to be able to ask questions to see if they are on the right track and get feedback from the sponsor.

PLEASE NOTE THAT ALL THE ENTRIES HAVE TO BE PRIVATE. SEE RULES AND PICTURES BELOW FOR MORE INFORMATION.

Requirements

  • The STEP file shows a prototype version of the machine with mounted panels that are bolted onto aluminum extrusions. The ENTIRE design needs to be CHANGED from a bolt-together chassis to an elegant stamped and folded SHEET METAL design with good structural characteristics and manufacturability kept in mind.

    PLEASE SEND AN E-MAIL TO challenges@grabcad.com for getting the STEP file.

  • The holes for the linear rods, the stepper motors, and channel cutouts inside of the inner shell must be maintained, and a spacing of 25mm from the internal shell of the machine, to where the outer panels mount, is needed for routing wires inside the machine. The linear rods and motors are load bearing, so the mounting points need to be able to withstand up to 100lbs force without issue.

  • The electronics will be housed at the bottom of the machine, and power will be brought in from the rear - a shelf 125mm tall and comprising half the length of the machine is needed for mounting everything.

  • There need to be four chambers for filament spools, that are accessible from the outside of the machine, that are environmentally sealed. The filament will feed through a tube to an extruder motor of which a STEP file of a mockup is included, which needs to be mounted inside of the machine close to the filament chambers. The filament spools need to be able to rotate easily inside the chambers - resting atop ball bearings is recommended.

  • The machine needs to have a large door with a viewing window to be able to see the model while it's being built. It needs to be weather sealed so the interior environment is fully isolated from the exterior during printing. An exhaust fan 80mm to 120mm needs to be included on either the top of side of the machine with room for a 6mm thick air filter to slide in tightly.

  • The front of the machine will also have an LCD, and on/off switch. The rear will have a standard computer power inlet. The design should focus on stamped sheet metal, with consideration given to cost when choosing metals (IE: Brushed stainless steel is nice, but fairly expensive in comparison to aluminum or powder coated steel). Covers for the filament chambers can be made from injection molded plastic, if desired.

  • The machine is equipped with a 4.3” Diagonal LCD. The LCD module is 67.3 x 105.34 x 4.15 mm^3, with a 53.86 x 95.4mm^2 viewing area, and should have 20mm of clearance behind it for mounting electronics.
    There is a standard ATX Power Inlet at rear of the machine.
    Spools are 200mm OD, 51mm ID, and 73mm thick, and weigh about 2.5 lbs. Take this into account when designing your mounting point so you don't warp or bend the metal.
    Native CAD files required at the end of the contest.
    Marketing grade renders are the end of the project are appreciated.
    If your design is chosen as the grand prize winner, we will likely require some minor changes to be made to accommodate actual parts prior to sending the design off for prototyping.

    i disagree with your comment that apple is a good example of industrial design. everything they make today is dysfunctional. their priority is self promotion - at the expense of end user experience. apple products represent all that is wrong with industrial design.

    Hello Ricardo - the concept sketches are recommended so you can receive early feedback on your design before getting too far into it, but are not necessary. The models, in their native format as well as STEP, will be required at the end. High quality 3D renders would be appreciated before the contest closes so that we can better visualize your design.

    The most important part, though, is to create a good, solid mechanical and industrial design based on the criteria above. Good luck! :)

    In the model I see support arms, but no tray or nozzle etc. It would be nice for rendering to add these but you dont want to give away too much detail of your product? What are the sizes of the filament spools and where to they go approximately? Where is the STEP model of the extruder motor?

    The step file I received contains only two nema17 motors and one nema23 motor. I guess those three are for x, y and z movements. In that case the extruder motor is missing. Is it in a separate STEP file and if it is can you please share that file as well? Are we supposed to position the extruder motor and thus the chambers anywhere we want? Do you permit changes to the inner shell? Is the inner shell made out of sheetmetal?

    Hello Everyone,

    You should be receiving some updated files here soon. The answers to the questions posed so far are below:

    The placement of the extruder is up to the contestants. Filament from it is delivered via a 4mm OD tube to the top center of the machine to a mounting point that cannot be shown currently, but is on level with the horizontal rods. The length of that tube needs to be minimal (so don't mount the extruders at the bottom of the machine and send a tube all the way to the top). You can see the tubing in the actual photograph of the part.

    Filament spools are 200mm OD, 51mm ID, and 73mm thick. There are four of them on the machines. We leave the mounting point flexible to the contestants, though we originally envisioned two spools on each side of the machine inside isolated canisters that functioned more or less like a Nikon lens cap, or being behind a sealed door. The filament tube would extend into the canister for loading, up to the motor drive, and then from the motor to the top middle of the machine.

    The inner shell of the machine can be modified (And should be! We want a stamped sheet metal design, not a bolt-together open frame, after all!). The only important portions there are the relative positioning of the holes and motors from one another (where rods, motors, etc. mount), and the build envelope to be maintained. The key with the mechanical design is manufacturability - something that's relatively easy to create by machine and isn't heavy on manual labor during final assembly.

    If anything is unclear do let us know!

  • Layered Labs

    Layered Labs over 1 year ago

    Tien Phuoc Nguyen: If I understand your question correctly, yes. There is one extruder drive for each filament spool.

    Nebojsa Djuric: There will likely be some changes that have to be made at the end of the challenge to accomodate real world parts, but submitted designs should be manufacturable - we'd like to be able to take the design and be able to run a prototype of it as is after the challenge.

    Aimo: Are you looking for a bend radius?

    Miguel Riego: Naturally we're only at liberty to discuss things related to the design challenge directly.
    I don't understand your question regarding the filament housing - the spool dimensions are posted above, and you can choose were to place them, be it on one side (or sides).
    The 25mm gap is for routing wires out of the bottom of the machine to the motors - provided that you have a means of doing this, you'll be OK.
    The larger motor can stick down into the electronics shelf.

  • Layered Labs

    Layered Labs over 1 year ago

    Tamas: In the STEP file it's part of mounting point for the horizontal rods, etc., and keeps the build area delineated from the rest of the machine. Provided you can still mount the parts shown in the same places you can replace it however you'd like. Remember that this is supposed to be changed from a bolt together frame to a stamped and folded sheet metal interior.
    Tien Phuoc Nguyen: You don't have to design any of the mechanisms for extrusion, just the full mechanical framework and exterior industrial design with the necessary mounting points preservedv

  • Layered Labs

    Layered Labs over 1 year ago

    We've gotten a lot of questions regarding the use of materials. You are not limited to using sheet metal only, per se. You can put in injection molded parts, extruded metal, and and any other such processes, but keep in mind that tooling for this kind of manufacturing can get expensive fairly quickly, particularly if first articles need modification and the tool needs to be redone. If you propose something particularly exotic be prepared to suggest how to get it manufactured effectively.

    There's a lot of design freedom given here - just follow the general criteria in the design brief and work towards coming up with something easy to manufacture, easy to assemble, and compelling in industrial design. :)

    "The assembly STEP file has been updated - two plates were missing which gave the impression of motors floating in free space, which have been restored. Note that the four blocks hanging off the side of the machine at the top are extruder drives - they are there just to show possible mounting arrangements, not because they need to be there specifically - place them however it is convenient for your designs.

    Harrel Holloway: The objection to a plastic shell is the cost of tooling for a mold of the size needed for this machine - we're not interested in using bolt on cut plastic panels as an alternative.

    Woodstock: There should be sufficient information in the model posted already to complete the design - we cannot provide the mechanics of our drive or extrusion mechanisms, unfortunately, but they don't have an impact on this portion of the design.

    @Layered Labs a little respect for the engineers and associates, those that worked hard on this project might be appreciated. 12 hours (on the day the "winner" is to be announced) might be appreciated. SOME response would be nice, at least an ACKNOWLEDGEMENT since you basically have 2 hours until the "END" (cst) OF 4/6/13.....

    @Layered Labs 12 HOURS since the last "contestant" asked when the winner would be announced.

    we all entered this contest under the assumption that you would (according to the agreed terms of the contest) declare the winner NO LATER than April 6th 2013. At least some acknowledgment that the contestants are inquiring about this "guarantee" to declare winners would be appreciated.

    I'm not upset, or angry. I'm simply stating that they have not followed the rules of their OWN competition. In doing so they forfeit the rights to work submitted - as this work was submitted with an expectation of propriety on the part of both parties.

    @Sara Sigel

    Thanks for posting those sara. But the fact remains that breach occurred, deleting my message so MORE people won't see it doesn't negate this fact. My demand still stands. As I'm not one of the "winners" anyway - I don't see how it should be much of a problem for Layered. However, if you would like to make this a "fight on principal" I'll be happy to oblige.

    Please Advise. If you would like to do so in private, feel free - as you have my email address. Rules are Rules - you expect us to live up to them - - why should you not be held to the same standard? The answer is: YOU SHOULD.

    @Grabcad ... I've noticed earlier a post from Bradley Abbott when he asked that you should release the IP for our competition entry and destroy the documentation that you received, due to not respecting YOUR OWN rules and deadlines specified in competition description. Now, that post is gone. As I can (clearly) remember, it was nothing injurious or offensive in it, so I can't see a reason for censoring one's words. Can we get an answer why a decent post was removed?

    @Phuoc Nguyen

    This is not an issue of justice for ME... it's an issue of the fairness of competitions hosted by GrabCAD.com. They (and the "competition hosts" like Layered) expect "contestants" who are basically just under-paid contractors (in some cases like this one) to produce according to a set of rules. But they THEMSELVES do not adhere to their OWN RULES. And when asked about it - feel empowered to act cavalier and ignore the "rules". When we asked about the winners, Sara told us: "we will announce the winners in a few months when we unveil the product" --- EVEN THOUGH THIS IS A DIRECT BREACH OF THE IMPLIED CONTRACT BETWEEN US AND THE SITE (as the rules specified a specific HARD DATE for this announcement).

    It's not "justice for me" - it's an issue of fidelity and adherance to the "rules" - FOR ALL PARTIES INVOLVED. Further - does anyone else here realize that according to the "GrabCAD TOS" - even though Layered (the Host) may not "choose" your project as the winner, ALL intellectual property you submitted becomes THEIRS REGARDLESS? This is basically unlawful according to UCC (for several reasons, not the least of which is a lack of "consideration" tranferred between the parties). More importantly however, their material breach of the agreement between the "submittor" and the "host" has provided grounds for invalidation of this transfer of property rights.

    I find it pretty wrong that they are "deleting" comments made that might cast their actions in a negative light - even though these comments do not violate the TOS. Censoring a user simply because he/she points out your bad behavior is the kind of thing you'd expect in an authoritarian regime - not on a "community website". This type of behavior further demonstrates the willingness to act in a deceptive manner - with total disregard for their OWN rules. I'm sure they will delete this message too.

    @Bradley Abbott, I don't know much about the US law, but I'm totally agree with you! and everybody will be agree with you! so. I have been seen all of past PRIVATE challenge, the 1st winner is a newbie (than me) had received the prizes.

    We do not allow threatening or harassing statements as part of our Community code of conduct. You, as Challenge participants, deserve to know who wins - so on April 6 we contacted the winners and posted them publicly as soon as they responded. If I won something, I would want to hear from Layered Labs personally congratulating me and not from a comment on a Challenge page. We do this out of respect for all of your hard work. Again, I apologize for the delay in our public announcement. I followed up with @Bradley.Abbott via email to respect his privacy. He may delete his work whenever he chooses without fear of Layered Labs using it. I recommend that others keep it as part of their portfolio and thank you for participating!

    People, let's try to be professional on this site. There have been some blatant arguments that really aren't necessary (ie, they don't add any value to the site and make us all look bad). I've noticed this from the start of the competition. Being constructive is what's important here.We should all try to get along in a professional manner and stop trying to 'prove' each other wrong, especially when it's with direct communication with the facilitators of the competition. They are trying their best and are providing an opportunity for all of us. Please be courtious and respect everyone. Thanks and congrats to the winners.

    Hello Every One (Including GrabCAD staff and Layered Labs). I would like to suggest something new for the projects which are held privately. All my suggesstions will improve the transparency of the competition as well as improve the design knowledge amongst the participan Following are my suggestion :
    1) After the private project winners have been announced(i.e. not before the winners announcement), all there private winning entry design concepts should be revealed during the time of announcement, this will lead to a more transparent competition results and will also help the runners up of the competition to know tthe shortcomings of there concept design(i.e. what made there design not a winning entry)
    2) The revelations of the winners design concept should include the pictures as well as notes on the uniqueness of there designs (i.e. what made there design a winning one among the competitors design.

    Thanks ... Congratulations to all winners !

    @Sara Sigel do know what is this company Layered Labs doing in the market now. Its been a year since they haven't launched there 3d printer in the market. There is no such name as layered labs in the 3d printer manufacturing company. Are they still in the process of manufacturing a 3d printer or they just didn't got the right design solutions from the grabcad design entries. If you find any website of layered labs then please do let me know asap ! Thanks
