A buyer’s checklist for sand mold and core printing – build envelope, sand and binder, accuracy, throughput per shift, post-processing, and machine versus service.

Printed sand molds cut lead time from 2-8 weeks to hours and remove pattern tooling entirely. Compare cycle time, cost by quantity, tolerance and design freedom.

Casting defects diagnosed by location rather than guesswork: gas vs shrinkage porosity, blowholes, hot tears and sand defects, with causes, fixes and a 22-row reference table.

3D printed sand casting vs investment casting compared: cost, surface finish, tolerance, part size, materials and lead time – plus a decision rule for choosing between them.

The complete guide to 3D sand printing defects: gassing, veining, metal penetration, friability, warpage and surface finish – with causes, prevention, and fixes for molds and cores.

Sand 3D printer buyer guide for British foundries: pricing, 6-8 week delivery to UK ports, compliance, export strength and net-zero casting, and 3DPTEK vs ExOne vs voxeljet.

Practical sand 3D printer maintenance: daily, weekly and monthly checklists for printheads, humidity control, recoater blades and binders – the habits that protect uptime.

Sand 3D printer buyer guide for Spanish foundries: pricing, 6-8 week delivery to Spanish ports, CE certification, growing market and AZTERLAN research, and 3DPTEK vs ExOne vs voxeljet.

Sand and binder selection for 3D sand printing: silica vs chromite vs ceramic sand, AFS grain fineness, furan vs phenolic vs inorganic binders, and the economics of binder loading.

voxeljet vs ExOne sand 3D printers compared: build volumes, price positioning, delivery and material systems – plus where 3DPTEK fits in the same size classes.
