    I found your info via Instructables. My boss at Huge Design asked me to look into a 3D printer for our firm. We are an Industrial Design Firm, we do mostly consumer electronics. The only thing I know about 3D printers is how cool they are. We requested and received a quote for the Stratasys Demension SST 1200 es. Now we think we need to research further, maybe to lease instead of buying.

    I’m hoping that you may shed some light and provide some information on how to even start looking into this. Anything you can do to help is greatly appreciated.

    All the best,


    p.s. do you do any designing? or know of anyone? we are hiring! :)

    I?m impressed, I need to say. Actually hardly ever do I encounter a blog that?s both educative and entertaining, and let me tell you, you will have hit the nail on the head. Your concept is outstanding; the difficulty is one thing that not enough persons are speaking intelligently about. I’m very completely happy that I stumbled throughout this in my search for one thing referring to this.

    Great printer! Once fully operational and optimized would you be interested in building one for me for fun and profit? Let me know what it would take to have one built. I am a master goldsmith and have designed a line of jewelry that has small modifications for each piece, which makes it a pain for hand carving but perfect for a 3D printer. E-mail me and let me know.

    Are you planning an selling kits a/o fully assembled printers. If so what time frame and estimated cost? I have no experience with the electronics and programming so building one from scratch myself is unrealistic, though putting together a kit may be feasible. Also if you need someone to cast your jewelry prints, I would be happy to. I’m a master goldsmith and do both centrifugal and vacuum lst wax casting. I really want to get started printing my own jewelry designs.

    @Daniel Hello!

    Your casting experience would come as a great help for me too. I am currently delivering test samples of resins to PZ and other DIY printer users. I have just finished preparing a couple of wax-filled resins for PZ to test investment casting, but another person with good background in this field could prove helpful. Would you like to participate in the R&D? If yes, contact me at spacecaptain at gmail dot com

    Hi there. I am working as part of a group interested in designing and building a 3D printer that utilizes DLP projector technology. I am a computer engineer and my responsibilities are focused currently on researching the slicing process. I am very new to this technology and have spent much time trying to learn all I can about STL files and how to generate layer images to be passed to the projector. You mention that you use Freesteel Slicer. I came across this software sometime ago and was having trouble implementing it properly. I would greatly appreciate any insight you can provide. I would have preferred to send you an email but did not see it posted anywhere on your website. Thanks for your time!

      Hi Vincent, I try to answer all comments here, so people can see the relevant updates. You can contact me via any of the services ( tweeter/Facebook/YouTube/ ) and also the Yahoo group.

      There is a new version from Martin of the slicer @Freesteel.co.uk. It had some bugfixes and now it is even better. I use it as a command line utility to slice the STL. There is an excellent information when you run it. but here is the parameters I use:

      slice -z 0,20,0.025 sphere.stl -o temp\output.png -w 1400 -h 1050

      Make sure you have created the temp ( or whatever you use ) directory.
      Glad to help. The license of the freesteel slicer is:
      “Slice is free to use and distribute in its binary form as a command-line utility. It can be aggregated with Free Software.”
      just to quote the author.

    Hi. I am working with Vincent on the DLP 3D Printing project and I am currently responsible for testing the resin to determine the right materials to use for the build platform and base. Currently we are using a quartz plate for the base but are having trouble with the resin sticking to it after it is cured. We are also trying to determine what material will be good for the build platform. I was looking through your blog and from what I can tell you initially used borosilicate glass for the base but are now using plexiglass. I also noticed some discussion of soda-lime glass. Can you please describe which materials you are currently using for the build platform and base and your reasons for choosing them? Any insight you have will be much appreciated.

    • Printer
      February 17th, 2012 at 10:59 | #21

      Hi Tim,
      Quartz was way to expensive for me. I ordered a borosilicate window 150mm X 150mm and 150mm X 200mm , but since I tested soda-lime glass and it works I saw no reason to waste the borosilicate on trials. Regular green glass works for the POC ( Proof of Concept ) and is readily available, and I can cut it myself to the sizes I need. Lately I have been using Plexiglas VAT for safety reasons since I cracked 5mm thick VAT during a test and did not want to have resin all over my projector or shards of glass. It is as a safety precaution that I use it for. Who knows, maybe it will be a permanent thing.

    February 17th, 2012 at 06:55 | #22

    Thank you! That information was very helpful in creating the slices. The one thing that concerns me is that the color of the images is inverted in reference to what I would like (i.e. black where I would like white and white where I would like back). For the printing process you would want the part of the layer you want cured to be white. I saw you had achieved this in one of your demonstration videos. I know it is not difficult to achieve by hand, but I was wondering if you are using a program or script to automate through all of the layered images. Perhaps it is part of the PowerPoint macro? I have not tested that yet.@Printer

      Hi Vincent,
      I’m using a utility called “Imagemagick” http://www.imagemagick.org . It can invert the images and save them to another format, if needed. It is a command line utility, just use:
      convert -negate filename (wildcards).

    How are you determining the thickness of the glass bottom of the build well, it seems to me that you need to find a refractive index that directs the UV image to be as perpendicular to the build platform as possible. I guess you could adjust the angle of the projector. I think looking into a transparent material with the properties of the fiber optic like Ulexite as the bottom of the build well. Also is this going to infringe the EnvsionTec patents??

    • Printer
      February 28th, 2012 at 23:15 | #25

      The thickness is determined by using the Snell Law and also http://www.atoglas.com/literature/pdf/81.pdf. The thickness does not make much of a difference. The projector angle is controlled via the XY position setting internal to the projector and also the refractive index of Plexi is very close to regular Soda-lime glass. For this POC it is not taken in consideration.

    I have read almost all of this site and I am still trying to figure out how this is different than the original envisionTec printers. I think it is cool if you are just trying to build one for yourself, but I find no new art this, or nay solutions for some of the issues inherent in the EnvisionTec design. I have used numerous EnvisionTec printers and there are issues that would really like solutions.

      February 28th, 2012 at 23:36 | #27

      It is very different. Do you know what a Reindeer/ Caribou looks like? Well a crocodile looks absolutely nothing like a Reindeer. LOL I used Part from the Hardware store and Envisionec used some high quality and CNC cut parts and both can do 25 micron ( and both can do even less). Were you expecting to find anything different between Roman Bricklaying and 3d Printer Voxels? How is the Coil Pottery technique different from a RepRap FDM? I have not used any 3D printer up this point and if you have problems with the Envisiontecs please share them and your concerns. Maybe I can help you fix your printer. Your other options are limited to only one: Call Envisiontec, wait for them to send you (a as a rental )some equipment to calibrate or rather compensate for a problem and keep loosing money and paying $7000 yearly + Monthly + $1500 for a $100 light bulb and not to mention the MSRP of the printer itself.
      Hope to hear from you with the problems you have with your printers.

      Here is the full Caribou joke:

      - Did you see a zebra?
      - I saw.
      - And what it looks like?
      - You’ve seen reindeer?
      - We have seen.
      - Well, like a deer, only black and white.
      - A giraffe did you see?
      - I saw.
      - And how it looks?
      - You’ve seen reindeer?
      - We have seen.
      - Well, like a deer, but with very long neck and spots.
      - A crocodile saw it?
      - I saw.
      - And what it looks like?
      - You’ve seen reindeer?
      - We have seen.
      - Well, the reindeer has nothing to do with the crocodile.

    All Joking aside, no matter how you move your build platform, the IP of Envisiontec is all about the use of a DLP projector projecting “masks” that solidify a photo-reactive resing in layers to build up 3D parts. Your project seems to use the same technology.
    For example Apple computer shut down every attempt to repackage their MAC computers by 3rd party manufactures, unlike the PC world where anyone can put together the parts, and sell the computers, they could even build one to look like a zebra, but if that zebra ran the Apple system their attorneys would be down on you very quickly. I am very interested in this, if it is possible then anyone can do it and so can I. But I don’t want Al’s attorneys after me.

      That is the difference! The software is open source and demo, except XP and PowerPoint. E-tech does not (Yet) own Bosch-Rexroth or patent for Dell Projectors, or bolts and washers, or Steppers and drivers, or plexiglass. It is more than 99% different from theirs. They can have their IP and me, mine. Also They can hire me( it would be much less expensive ), instead of shutting me down . So it is not running Envisiont*c OS or code. Following your logic, you cannot fix your car with another part or bolt, or wire that is not branded/approved from your car manufacturer, or even drive it since you do not have permission/contract from/with the manufacturer.
      Keep watching…for further developments (Pun intended)… ;-)

    March 3rd, 2012 at 05:28 | #32

    I must really not understand IP laws, I am under the impression that you can copy whatever you want for your own use, but you cannot do so to sell it. You don’t need to be running their code but if you are using their concept without new art you violate their IP. Maybe you can use the same overall method but design your own software and hardware to accomplish the same effects, not sure how that plays out. As far as 3D Systems, the courts decided that the Envisiontec method was new art and could go forward. On the 3D Systems website it says they won the judgement but really they won nothing, Envisiontec was not using their method. I am really interested in the law here, because when I first saw a EnvisionTec machine in 2002 in Chicago, I got a look inside and told my clients to go ahead and buy them, because even it the company went out of business the machines were very simple to fix or rebuild, or build for that matter. So I am curious to see if you can commercialize your machine.

    I’d very much like to build one of these to use in my business. I’d like to be able to print small model ship parts that can be as small as 1mm cubed. However, the THK slide is way out of my affordable range. Is there a slide that you could recommend with similar specs but much less expensive?

    Another question? Would you be interested in taking print orders? If I sent you an STL file, for example, for model ship belaying pins that are about 1/2″ long, say 20 of them on a sprue, would you be interested in printing them for a fee and on a routine basis? Probably not but doesn’t hurt to ask.

      Hi Bob Hunt,
      What is the matter with you??? I have not deleted a single post, I just have not gotten to approve some comments. Keep in mind there is a time difference between continents EUROPE and AMERICAS, not to mention Holidays or (God forbid) should I be someplace without Internet for couple of days. Are you aware you are not the only one asking questions and needing time to answer? If it is out of your budget, it is not my problem (It is out of my budget too, but I have made some sacrifices to save money to get it or sell some( 5 )DVDs @ $120 a pop). Wonderful historic city you are in. BTW – Congratulations on becoming a S Corporation! ( makes me wonder how a small, teeny, tiny THK KR20 linear slide is out of your budget since you have experienced such exponential growth and converted to such a conglomerate, multinational and global “S” Corp. Gasp!).

      Have respect for others that have a hobby, as you had and started the same way.

      Now onto business…
      I could say I have no obligation to give you any alternative recommendations, but there you go: check with BOSCH, DELTRON, Parker-Daedal, Aerotech. I’m sure that after you check with them, THK in comparison will seem like a cheap Hundai. Check the prices for Hi-win for a budget price, but keep in mind you have an accuracy grade to watch out for with all manufacturers. You could make your own or have friend/friends that can help you with it.
      It is not an open source – it is just OPEN period. If you want to help with something e-mail me your skills and what you can help with ( money is always be nice ) if you are so eager to get answers. I have shared “this kind of information” with everyone and I have not received complaints that THK is expensive.
      I don’t feel insulted or offended for not deleting your post, so why are you?

      Grab some Jack’n’Coke or your choice of tranquilizers and relax a little.
      I’m on a glass of “Bloody Mary” myself.

      Hi Bob, To set the record straight from my point of view: I did not accuse you of being a liar – Maybe you did not see the “Your comment is awaiting moderation.” on top when you posted. All posts go through a SPAM filter and then I also approve them. The comments are visible only to you and when you close the page they are what you consider GONE (and it is not about the cookies or browser), but they are not. You would not believe the amount that gets posted by bots and SPAM. You can still find the answers and ask questions, I’ll gladly answer them, but for the tone you set from the third message…never mind, we’ve spent/wasted enough time… start over on the right foot…

      I gave you more than enough to go on. Check with ebay/craig list/local automation dealer/telephone directory/websites. I have no list of cheap/expensive suppliers and prices. As I’m not in the US I cannot do the legwork/ebay bidding/ or make the phone calls for you. Distributors in different countries have different price policies. I have picked a reasonable product for my needs and went with it. The Z axis is made up by an item called “Linear Slide” / “Linear Module” model KR20 from THK. I have mentioned it in the blog a lot as a term. Couple those with the manufacturers I’ve mentioned and you can get a long list from ebay. Since you knew it was too expensive for your budget I assumed you searched and found the prices in ebay/craig list…

      Keep bothering me, but do not expect an answer right away. When I have time ( we have families/responsibilities/holidays/Unplug time – no internet/fishing and so on ) I will answer as I have done to everyone. I know the speed of life in the US can falsely give you the impression that everyone is obligated to answer in 10 min, but in some countries ( Italy for example, hope no offense is taken ) I waited 2 weeks to get an answer about some item and prices.

      Hi Daniel,
      I’m only providing information on how others can build a 3D DLP based printers. The electronics are not that complicated and the software is open source/freeware.
      I also worked in design and ended up building a printer. It is possible to build a larger size, but there is a physical limit ( I have not tested larger, but have tested smaller ) when the suction force will be too great to overcome and will break something. That is one reason to consider a top lit ( or the projector shining down in a deep VAT of resin. The down side is the cost to fill a 10 or 20 liter VAT considering the price of resin per liter.

    Thanks for your blog, its a very interesting read!

    I’m an engineering student in the UK and would like to build a DLP printer for a project. I’m pretty clear on most of the issues you discuss, however I don’t understand why movement of the vat (X and tilt) is necessary. Could you elaborate on why this is required?

      Hi Bruce,
      The X ( or whichever you designate to run the VAT ) is not necessary if you can get around the vacuum forces generated by the Z axis separating the cured layer.
      Some, like Mike from b9creator use sliding to overcome the forces following a release of a document from University of Texas . There, you can see the actual numbers of the tests.

    Hi Peter,

    I love the Blog. Been reading it all week and fascinated by all your progress and the details of your work. Its inspiring me to give it a try too. I had to questions I was hoping you can answer that I didn’t find on the blog. Is it possible to position your projector further from the vat and get a larger build area or is it where it is due to the image scale? Secondly, I’ve been playing around with the software and can’t figure out how you are doing what you do with Freesteel. Are you running it on Windows via the command prompt or on a Linux machine? Can you offer and advice on that or recommend a another program that will create the PNG images of the STL slices?

      Hi Dave,
      It is possible to move it further away and enlarge the build envelope, but you will have a lower resolution ( say 100micron instead of 50micron in XY).
      You also run into another snag – the larger build area also has a stronger suction force from the resin layers being separated from the VAT.

      As to FreeSteel – I’m running it from a DOS prompt and also I aggregated it in a small VB Utility to browse for the STL, Slice it and preview the slices before I assemble them. Then onto PowerPoint. You can look in the Yahoo Group “Files” section for Paolo’s(I think) “STL” slicer. Skeinforge does serve a purpose, but it is very slow in slicing STLs for DLP.

    Thanks for getting back to me. I haven’t found Paolo’s STL Slicer yet for trial, but I did try a few. Netfabb was first and looked impressive, however the free basic version would make and display slices, but unless you upgraded to the professional version and bought the slicer add-on then it would not let you export the SVG file. It was too expensive for me at this point when you consider that I don’t have a printer yet. Took a look at Slice and Dice next, but I don’t think it will work for me or at least I have figured it out yet. From what I read it sounds like earlier versions of it actual used the PNG format, but it was later changed. Next was slic3r and it did export layers to a single SVG file in which I was able to read using Adobe Illustrator. This seems like it will work for me with a massive amount of time, saving each layer one by one, editing each image, then arranging them into powerpoint. I was hoping for something that saved each slice as a separate image with a numerical sequence in the file name to keep them in order. I am sure there is an easier way, but at least I have a potential path to make the images I need to drive the printer. This was what I needed to do before taken the leap to build a printer of my own. I’ll figure out an easier way later or maybe someone will have figured out the software by the time I finish building mine.

    Thanks for the inspiration Peter,

      Hi Dave,
      I had some problems with the backend, but all resolved now.
      The slicer I use is the FreeSteel Slicer. It slices and saves the slices in PNG/BMP/SVG and some other formats.
      I then run them through ImageMagick if I need to change the backgrounds/enhance/Antialiasing.
      For now I have found that Freesteel seems to be running fairly fast and smooth.
      You can also try the Paolo STL Slicer in the “Files” section of the Yahoo Group:

      Look for STL_.zip

    Hi, I’m interested to build one of this 3D DLP printer for hobby and prototyping 3D designs.
    Are the files here meets the basic requirement for initial trial?
    If I could consult to you by email, it would help a lot.

    Dear Sir, please provide me your contact mail and Skype or phone number and appropriate time for conversation regarding 3DLP technologies. I was following your blog but after April this year dare is no new posts. I’m building one according your posts and i have some question regarding VAT and necessity of tilting process. Best regards Raca Sasha

      Hi Raca Sasha,
      I consider the project complete and do not feel the need to indulge you in showing you pictures of the printer enclosed in black plastic, so I do not have much to update.
      Contact me via one of the other services ( facebook/youtube) to share contact info.

      Hi Kacey,
      I have no blueprints per say. Everything is listed here.
