I have a delta with 3 extruders suspended from the top by 3 cables and counterweight system. A video at Printing perimeters at 30 mm/s infill at 60mm/s and travel at 120 mm/s Motors Nema 17 - 70 oz-in More pictures of the printer with only 1 extruderby Xabbax - Delta Machines

QuoteOttoBunge How did you guys solve the delamination problem in tall slim prints? (with a good infill I can avoid any serious delamination) Layer height: 0.2 print speed: 30mm/s ABS temp: 235°C HPB temp: starts at 90°C goes to 110°C Increase speed, increase temperature to 245 or more depending on the filament and enclose print in heated chamber without any draughts.

Quotedave3d Thanks Xabbax. Yes, can you post the OpenScad code. That would be useful. The tubes look to be at about 45 deg. Is that right? 30 deg from verticalby Xabbax - General
Quotedave3d Thanks Xabbax. I visited your website. I like the welding nozzles idea. Couple of further questions:- - what is the centre hole in the heating block for? - is the water cooling by natural convection or forced circulation with a pump? If so what kind have you used? I would like to build one. I have tried twin nozzles with a Bowden setup on my OrdBot. The problem was getting them lby Xabbax - General
QuoteFeign This thing is absolutely brilliant by the way, I love it and would like to see more. More pictures on my websiteby Xabbax - General
Quotedave3d Wow. This has got to be the way forward. So light and compact. Questions: - are there no PTFE liners in the tubes? - I assume you are using 1.75mm filament, are the stainless tubes 2mm id? - are the tubes a press fit in the hot end? - I can't see what the central tube does. You are using 3 colours, right? Looks like 2 stage heating element. Is it soldered to the brass fittings onby Xabbax - General
Some images to see how to make your own hotend. With the latest release of Repetier-Host V1.0.3 it is easier to handle different colours in a printby Xabbax - General

Any open source software available for colour mixing of 3 or more colours? I know Repetier is working on a solution - - Anyone else? I got my 3 colour hotend on a delta working - now for colour mixing.by Xabbax - General
Another idea for the towers may be the traditional 2 rods per tower of the Kossel but instead of steel use 2 glass tubes ( neon light tubes of various sizes are available ) Print a glider with holes at the right places - insert 4mm ptfe tubing and two screws for fine tuning.by Xabbax - Delta Machines
I like it - clever design. Idlers on the corners of the motor and you have a compact setup. This concept will be handy with a Cablebot design ( )by Xabbax - Developers
QuoteWildcard Looks nice! I enclosed my printer in a case made of Lexan and wood. It doesn't add much weight, but to make the entire setup more stable, it is all attached to a table via bolts. Is yours attached via bolts to the table? If it is not attached to the table do the weights keep it stable, or if it is attached to the table are the weights used just to counteract any rocking that occurs?by Xabbax - Delta Machines
Quotersenas the weight of this structure and the quality of parts made stands compared to its previous. Hugs. It is a heavy structure with the six 900x300 glass panes, the ceramic tile and the 2 boards at the top and the bottom. Prints are better but the best is that I do not get lift of corners of big partsby Xabbax - Delta Machines
Scalable low cost delta printer with a 4mm window glass structure to enclose the printing area for a heated chamber. Want to be able to print ABS without de-lamination and lifting from bed problems. The glass held in place by 6 x 5mm bolts and 20 mm T sections glued at the corners with silicone. One or two glass panels free to slide at the front. Top and bottom - 16 mm builders board.

Quoteibpsrs I think it quite differently, sharp teeth will bring grip, but they have the terrible side effect of grinding the filament (see in the post below). Square teeth are better in this way. I found a problem with torx round teeth too: they need really high idler pressure, much higher than i thought.... I found another design, MoonCactus hobbed bolt, it is really easy to make with a dremeby Xabbax - Plastic Extruder Working Group

QuoteDougwar Hi, I'm trying to do a filament extruder and I get this; too many bubbles in it, temperature were 190C, do you have any suggestion? what's the dimension between the nozzle and the auger? Thanks I think the temperature may be a bit high hence the bubbles. Distance between the augers tip and the nozzles inner surface: 80-10 = 70 mmby Xabbax - Plastic Extruder Working Group
Thank you for the hard work and sharing of the idea. This can also be used for the rotation of the printhead when you have a rectangular hole in the nozzle. One side of the nozzle can then follow the direction vector of the nozzle. Will be handy for the printing of concrete and other similar materials. Can also be used to add stuff like carbon fibre to a print for added strength.by Xabbax - Wire and Thread Embedded Extrusion
QuoteArnold Hi all, what do you use for successful sticking ABS to heatbead ? Iam not successful with hairspray, it is good but not enough. When I print just frame (wall with 1mm thickness) always one side lifts up like on the picture. Is it better kapton tape with aceton/abs mix, or hairspray ? Actually what is the best, or how to prevent to lift ABS up ? Nozzle: 230°C Bed: 110°C I also had thby Xabbax - Printing
