To print, we need files in either an .stl or .obj format. Most CAD packages should be able to handle this. Sketchup Pro needs the addition of an .stl add-on.
With the Ultimaker S5, we can print to just under 330 x 240 x 300 mm. However, a typical item printed to take full advantage of this volume would take some 50-100 hours to print out. The longest print we’ve so far done ran for three and a half days. This was a 15cm high copy of a bird statue which required a lot of support material. See below.
Three and a Half Day print
For recent eight hour prints, we have been dealing with objects measuring 90*70*45mm (a toy), or 110*55*25mm (a relatively uncomplicated architectural model)
2 hours could involve a toy of 50*40*25mm or the architectural model of 60*30*15
A 27 hour print involved a building measuring 165*65*70
We can speed printing by switching to a coarser nozzle, which can give perfectly decent results for many jobs.
For more delicate results, we can switch to a finer nozzle, which will double print times.
If you need to print beyond our 330*240*300 mm limitations, it is possible to break designs down to print in pieces.
We can print in PLA, which is a biodegradable plastic optimised for 3D Printing (good surface finish etc). If you need an item which will go into a serious working environment, then we can offer other materials, including nylon, resins and various high-performance co-polyesters.
Layer depth can be as fine as 60 microns. On the x/y axis the limit is probably around 250 microns
fine lettering gets increasingly difficult as we scale down
We find it hard delivering quality printing as elements get down to the 1mm range.
When designing, bear in mind
Overhangs of more than 60% may involve support “scaffolding” which will slow printing and may involve some post-print processing
Stable printing is helped if a design has a substantial base. Tall items on an insubstantial footprint can slip out of vertical when printing, at which point the prints have to be aborted.
One subtle issue is that designs done at real-life dimensions (several metres and upwards) which are then scaled down for printing can sometimes become unprintable because elements become too fine for printing. If we’re using our standard .4mm nozzle, elements should be bigger than that (walls, columns etc).
This is a particular problem with architectural practices seeking to reduce their designs down for printing display models
If this happens, you would need to tweak your design to make it printable.
We aim to match prices found on national comparison sites - with a small "Cornish" surcharge to reflect the personalised service and advice we aim to offer.
Many hobbyist jobs come in for around £10.
Smaller commercial ones will often fall in the £15-50 region.
Multi-day commissions, involving high-performance filaments will be significantly more expensive than that.
