Frequently Asked Questions
I want to know, what makes your printer different ?. Iv'e seen a lot of 3D printers pop up on Kickstarter lately but I want to know what sets your printer a part.
Our Open Source printer is based on a delta robot, known for it's use in pick and place operations. Due to the light end effector, it can move very fast. All heavy parts such as motors are stationary, as is the part being printed. The frame is self-aligning by design and very easy to assemble. Being very sturdy, the printer does not require frequent calibration. Also, a reduced numbers of components, good cable management and good design practice leads to a machine which looks good in a design office. As materials ABS and PLA have been tested, with the machine accepting coils up to 1kg from any manufacturer. Finally, the use of quality components, such as German made Igus linear slides, ensure durability and a reliable operation. The focus with the printer has been for out right performance, high quality, and pleasing aesthetics, with the cost factor being of secondary importance.Last updated:
So far, the highest speed we have been printing at is 150 mm/s for infill speed and 250 mm/s for travel speed.Last updated:
You will need several tools to complete a comprehensive kit:
- cross head (pozidriv) screw driver
- small allen (hex) keys
- terminal screw driver
- multi meter
Optional, but recommended:
- Electric drill and/or electric screw driver plus pozidriv bit.Last updated:
The build area is 275mm in diameter and 250mm + high. If you were to print a rocket, the highest point of the rocket could be a bit higher than the 250mm.
Without the coil holder, the printer is 491mm wide, 500mm deep, and 758mm high. The detachable coil holder can be mounted on the top or the side, making the printer higher or wider.Last updated:
The kits will come with a 0.3mm nozzle AND a 0.5mm nozzle, so you can choose yourself which one to use.Last updated:
That would be our company logo. The 'wonky cross' is the nordic rune 'Nauthiz', which represents necessity. As necessity is the mother of all inventions, it fits in well with the design-driven and solution based approach of Tegelbeckers Ltd.Last updated:
After the Kickstarter finishes successfully and you would receive a kit, you will be able to choose between having the printed parts made by us, or alternatively you can choose to receive some of our high quality material for printing by yourself!Last updated:
Earlier this month we showed off our printer on the Develop3D live event in the UK: http://www.develop3dlive.com/ At the event, the suggestion was made that we would be able to sell the printer for double the price. At some stage someone walked up to us and said: 'so this is the stupidly cheap printer everyone is talking about'. By seeing the printer in real life, it can be appreciated for what it is, which is also the reason we ended up bringing it to the exhibition.
The Bill Of Material for the initial plywood prototype can be found in step 6 of my Instructable: http://www.instructables.com/id/DeltaTrix-3D-Printer/
The offered printer on Kickstarter differs in several ways, amongst others:
- The frame material is now treated Valchromat.
- The electronics are now based on the RUMBA board, being a higher spec alternative to the earlier RAMPS solution.
- New stepper drivers are now 1/32 microstepping.
- The stepper motors now have double the resolution, ie. 400 steps per revolution.
- Carbon fibre rods and tension springs replace steel rods and rubber bands.
- The square bed has been replaced with a round bed, featuring a purpose made silicon heater pad. This upgrade in itself costs us in the order of £50.
- The power supply is now a 400Watt unit, featuring our own purpose-made cover.
- Improved LCD surround.
- Proper connectors are used for the quick change print head and the new heated bed. As proper crimping tools would be needed for fitting the connectors, we will supply complete cable looms for Kickstarter.
See the following links to get an idea of the costs involved for some of our components:
Igus rail (600mm long|) and carriage, 3 off.
Male rod ends for carbon rods, 12 off.
RUMBA electronics, 1 off.
ReprapPro Hot end, 1 off + extra nozzle.
A lot of our cost is in the CNC machined frame components, which we are offering for £125 as a separate set. If we are only meeting our minimal target, we would only just be able to break even on this as there are setup costs involved and CNC machining is not the cheapest option for producing stuff (see CNC machined ibook for reference...). As the resulting frame is very sturdy (no shaking during high speed printing!) and the finish is so stunning, we feel it is well worth the expense.
The price of our printer kit is higher than the cheapest around as we use high quality components and we do not cut corners on any aspect. Anyone in the market for the cheapest printer possible should skip ours. We would like to target the most demanding maker and the professional design engineer, who appreciate high performance, quality, and inspiring design.Last updated:
